<para>
This document describes the use of mondo and mindi tools to realize disaster recovery backup of your systems. It provides information on installation, backup and restore modes, hardware and software requirements, and answers to some frequently asked questions.
The goals are to offer a general view of the functions and their best usages.
Mondo Rescue is a Disaster Recovery Solution which allows you
to effortlessly backup and interactively restore Linux, Windows and
other supported filesystem partitions to/from CD/DVD-+R/RW media, tape,
NFS, ... and Mindi Linux provides the bootable emergency restore
CD/floppy set which Mondo uses at boot-time.

<title>Purpose / Scope of this Guide</title>

<para>
This HOWTO serves to help people get started with using
mondo/mindi as way to backup/restore their system. This is a work
constantly evolving. It was started by Hugo Rabson and has
since been worked upon by a number of people. See the
'<ulink url="&WWWB;about.html#devteam">About</ulink>' web
page for a list of members of the development team.</para>

<para>There are many ways to contribute to the Linux movement
without actually writing code. One of the most important is writing
documentation, allowing each person to share their knowledge with
thousands of others around the world. This HOWTO is designed to
help you get familiar with how Mondo/Mindi works.</para>

<para>
Opinions expressed here are those of the authors.
Informations are provided in the aim to be useful to the readers.
However, there can't be, through this document, any warranty of any kind
on the way it works on your systems, nor the author could be responsible for any problem caused by the use of these informations.
However, software editors don't garantee you a lot either (re-read the contracts).

I am also willing to answer general questions on MondoRescue, the best I can.
Before doing so, please read all of the information in this HOWTO, and then send me detailed information about the problem, especially including the logs generated by the tools, or traces obtained (Did I say that already :-].

Choose from the list of supported backup media types. The media you
will use most often are CD/DVD-+R, CD/DVD-+RW, tape, NFS and hard disk. If
you want to backup/restore over a network, choose 'NFS'. If you
want to backup/restore to/from a local partition or if you simply
want to store the ISO images in a local directory until you have
time or facilities to burn them to CD's, choose 'hard disk'. If you
choose 'CD/DVD-R[W]' or 'tape' then in general your hardware will be
detected and configured for you.

        If you are backing up to CD/DVD-+R[W] then Mondo will ask you if your CD

Is your kernel sane? Red Hat, Mandrake, SuSE, Debian and Slackware users
should in general say 'yes' because these vendors are good at

The backup process will now commence. There are some pre-backup
tasks to be carried out first but the backup is essentially
underway. To simplify the backup process, you were asked a series
of questions. Next time, if you like, you could call mondoarchive
with various command-line switches to control its behavior, instead
of answering a series of questions. See the man page for details.

Mondo will make a catalog of all files to be backed up. This may
take up to five minutes. The list of files will be divided into
sets, approximately 4 MB (before compression) of files per set.
This typically takes one minute.

Mondo calls Mindi. Mindi generates bootable floppy disk images and
auxiliary data disk images which are based on your existing Linux
distribution and filesystem. That way, you can be sure Mondo's
tools will be compatible with your existing filesystems and
binaries: Mondo's tools are your tools. Mindi takes up to five
minutes to run.

Finally, Mondo begins backing up your computer. This process may
take a few minutes or a few hours, depending on how much data you
are archiving, how fast your CPU is, how much RAM you have, and so
on. It will backup your regular files and then your large files
(files larger than approximately 32MB). If you have opted to verify
your backups, Mondo will do that too.

Do you want to create a boot floppy at the end? Yes, if you're a
tape or NFS user. No, if you are using CD/DVD-R[W]'s and your computer
supports bootable CD's. Tape users only need one floppy but other
users may need more. Mondo will advise accordingly.

<para>The 'c' means you must be writing to CD-Rs, not CD-RWs (the
latter would require 'w' instead of 'c'). The '4' is the speed of
your CD writer. The string after -I is the path to be backed up.
The '-gF' means you are going to see the pretty yellow-on-blue
screen instead of the boring white-on-black screen. :) It also
means Mondo will not offer to create physical boot floppies for
you. It is assumed that you are able to boot from the CD which
Mondo has generated.</para>

<para>Note that you have to mount the NFS partition, backup to it,
unmount it, and create a boot CD to allow you to restore from

restore from the NFS share even if your PC is wiped, please boot
from the Mindi CD and type 'compare'. The on-screen instructions

<para>In this case, we assume Syslinux is incompatible with your
boot media. For some reason, some BIOSes just don't like Syslinux.
If you find this to be the case for your computer, please use '-L'
to force Mondo to use LILO instead of Syslinux as the boot loader
for its CD/floppies. (NB: This has nothing to do with which boot
loader your hard drive uses.) Also, it is a good habit to specify
your tape streamer with '-d &lt;device&gt;'. You don't usually need
to but it's good to be on the safe side. Some computers call your
tape streamer /dev/osst0, some call it /dev/ftape, ...</para>

<sect1 id="overview-mondorescue">
<title>Mondo Rescue</title>
<para>Mondo Rescue backs up your file system to CD, tape, NFS
(archives stored remotely) or ISO's (archives stored locally).
Mondo uses afio as the backup engine; afio is a well-respected
replacement for tar. In the event of catastrophic data loss, you
may restore some or all of your system, even if your hard drives
are now blank. Mondo Rescue can do a lot of other cool
things:</para>
<itemizedlist>
<listitem>
<para>You can use Mondo to clone an installation of Linux. Just
backup the crucial stuff and exclude /home, /var/log, etc.</para>
</listitem>
<listitem>
<para>You can backup a non-RAID file system and restore it as RAID
including the root partition (if your kernel supports that).</para>
</listitem>
<listitem>
<para>You can backup a system running on one format and restore as
another format.</para>
</listitem>
<listitem>
<para>You can restructure your partitions, e.g. shrink/enlarge,
reassign devices, add hard drives, etc, before you partition and
format your drives. Mondo will restore your data and amend
/etc/lilo.conf and /etc/fstab accordingly.</para>
</listitem>
<listitem>
<para>You can backup Linux/Windows systems, including the boot
sectors. Mondo will make everything right at restore-time.
(However, do run "Scandisk" when you first boot into Windows, just
in case.)</para>
</listitem>
<listitem>
<para>You can use your Mondo backup CD to verify the integrity of
your computer.</para>
</listitem>
</itemizedlist>
<para>Mondo's principal virtue is that it protects you from the
problems that can arise when you reinstall completely from scratch.
If you want to wipe and restore your system every year just as a
matter of 'good practice', Mondo is not for you. However, if you
want to get up and running again in a hurry after someone breaks
into your computer and wipes it (or if you accidentally wipe it
yourself) then Mondo is definitely for you. It will permit you to
roll back to a known-good installation in a very short period of
time, sometimes as little as twenty minutes. Even if you backup
large amounts of data to tape daily and do not want to add yet
another backup regime, please consider backing up the core
filesystem (i.e. everything but the directories containing your
huge database and your prizewinning novel) every month or so, just
in case. You will be glad you did.</para>
<para>What is Mondo not?</para>
<para>Mondo is not an everyday backup program. It is not designed
to replace tar, afio, kbackup, etc. Mondo is designed to make it
possible to recover from scratch if necessary. Tar and afio offer a
quick, convenient way to backup small sets of files, sometimes to
removable media.</para>
</sect1>

<sect1 id="overview-mindi">
<title>Mindi</title>
<para>
Mindi Linux creates a set of boot/root floppy disk images
that will let you perform basic system maintenance on your Linux
distro. The principal virtues of Mindi's boot disks are the fact
that they contain your kernel, modules, tools and libraries. You
can ask for additional binaries (or other files) to be included on
the kit. The libraries will be added for you.
</para>
<para>Whichever modules were loaded at backup-time, they are
reloaded at boot-time. So, in theory, you will boot into almost the
same environment as you were in when you backed up. If you want to
add files to your Mindi boot disks, edit '&lt;INSTALLPATH OF
MINDI&gt;/mindi/deplist.txt' and add the files to that list. The
added files and dependencies, will be spread across the data disks
at run-time.
</para>
<para>Mindi makes sure that Mondo has all the tools it needs at
boot-time. Mondo uses fdisk, mkfs, cat, less, more, afio, gzip,
bzip2, your keyboard configuration, your glibc libraries, your
other libraries, your kernel, your modules, ... a lot! Mindi takes
care of all that, so that Mondo can get on with the job of backing
up or restoring your data.
</para>
<para>Mindi is also handy for making boot CDs/disks which stand on
their own. You do not need Mondo. Indeed, if you like, you could
use another backup/restore program with Mindi. Just add it to
Mindi's dependency list (type 'locate deplist.txt' to find it).
Mindi will include your software on its boot CD/disks the next time
you run mindi.
</para>
</sect1>


<sect1 id="overview-linuxbackup">
<title>Linux Backup</title>
<para>Mondo Rescue and Mindi Linux are used primarily as Linux
backup and cloning tools. The fall in prices of CD-RW drives and
writable discs will allow current users to keep good backups and
future users to leverage the cloning capability.</para>
<para>Tape drives are more likely to suit your needs if you run a
larger installation (or have lots of MP3's). Warning! OnStream
drives do not play well with Mondo. I do not know why. It is, in my
opinion, something which OnStream should look into. Mondo uses
fopen(), fread(), fwrite() and fclose() to interact with tape
drives. That works for most drives but some drives just don't like
that.</para>
<para>I have tested it thousands of times on my own computer with
my own data and with no alternate backup regime. It worked for me.
Thousands of users testify to Mondo's stability and its ease of
use. However, please test it on your own system before you rely on
it. In fact, do not rely on any software until you have tested it
to see if it performs as expected.</para>
<para>To establish that Mondo will behave well in an emergency,
please be prepared. Run a test backup as follows:-</para>

<para>FYI, the subroutines to repartition and reformat your drives
are very stable. If you are a RAID or LVM user, you
might&nbsp;encounter some difficulties when wiping and restoring
from scratch because of the sheer range of filesystem layouts and
the impossibility of testing Mondo on every single one. If you have
trouble, just drop to the command-line and partition/format
manually. Then, call mondorestore, select Interactive Mode, and say
'no' when asked if you want Mondo to partition or format your
drives for you.</para>
<para>You see, even if you have trouble, you still have two hands
and most of the tools you need - lvchange, pvcreate, fdisk, mkraid,
etc. - to do it manually. After you have prepped and formatted your
drives manually (if you have to), just run mondorestore again and
say 'no' when asked if you want to prep or format your drives. What
could be easier?</para>

reflect the size and type of the partition. The user may not edit
that partition's size at restore-time (for obvious reasons).</para>

<title>Mondo Rescue and Mindi Linux
History</title>
<para>Mondo Rescue was created in December 1999 as a utility to
clone Linux/Windows installations. Norton Ghost would not do the
job, and my boss wanted to jump on the Linux bandwagon. So, I wrote
a few scripts and shoehorned them into the latest Linux-Mandrake
CD. Since that time, Mondo grew into a disaster recovery suite for
Linux and Windows. Mondo forced me to learn about the kernel, its
initrd initial ramdisk, modules, library dependencies, disk
partitioning, and the myriad differences between the Top 10 Linux
distributions.</para>

<para>The first formal release was made on February 18th, 2000.
Mondo is currently one of the top five Linux backup/restore
programs. Mondo has been compared favorably to ArcServe, Arkeia and
BRU. Although Mondo lacks the more advanced, enterprise-level
features of ArcServe and Arkeia, for workstations and small- to
medium-size servers it is ideal because it is small, fast,
efficient, stable, comes with source code, and is being actively
developed and supported.</para>

a CD-RW disk in it. (Use -Oc instead of -Ow if you are using
CD-R.)</para>

ending in '&amp;#732;', logs, temporary files, /etc/mtab,
/etc/adjtimex - then you know the archives are good. Your logs will
change over time, too. Bear in mind that a difference between the
backup and the live copy does not&nbsp;indicate a flaw in Mondo. It
indicates that you or your filesystem changed the files, so the
backup is no longer 100% up to date. However, that is inevitable,

<para>Imagine that your hard drives happen to be wiped,

</itemizedlist>
<para>That's it. The restoration process for tape or NFS users is
similarly easy: just boot, answer the on-screen prompts, and
wait.</para>
<para>Now, should something go wrong, you will be able to examine
/tmp/mondo-restore.log to see what happened. All is not lost. You
can fdisk and format the partitions yourself, using the tools that
come with the CD. You can then run mondorestore in Interactive Mode
and say 'no' when asked if you want Mondo to partition/format your
drives.</para>

</sect2><sect2 id="AEN40"><title>9.2.2. Interactive Restore</title>
<para>Interactive Mode is for people who have lost a subset of data
from their live file system, or perhaps who have lost some data
from their latest backup and want to restore a subset of data from
an earlier backup. If you want to restore only some files or if you
do not want to prep/format your drives, then you should boot into
Interactive Mode. The interactive mode will provide an 'Editing
mountlist screen' that allows you to setup a different disk
geometry.</para>
<para>To move up and down between partitions in the 'Editing
mountlist screen', use the Up and Down arrows. To move between the
main window and the buttons at the bottom, use the Left and Right
cursor keys. TAB shifts focus from one screen item to the other in
a haphazard fashion, owing to the complexities of the Newt
library.</para>
<para>If you want to restore selectively, just press &lt;enter&gt;
and follow the on-screen instructions. You will be asked to say
yes/no to a range of questions.</para>
<para>If you are planning to modify your partition table, you would
do well to read up on the partition layout and the use of fdisk, it
gives you some could pointers on how to best lay out partitions.

Restore to a different disk geometry</title>
<para>One of the nice things about Mondo is that it lets you wipe
your existing system and restore it in any layout you like (within
reason). You can move from non-RAID to RAID,install and utilize
additional drives, move from ext2 to ReiserFS, etc., all without
risking the loss of data.</para>
<para>If the user excluded a particular partition from backup and
specifically excluded it from the mountlist itself using -E then
Mondo will insert a small (32MB) partition at restore-time, in

etc.</para>

<para>If you want to move from ext2 to ReiserFS, you can do it here
(so long as your kernel supports ReiserFS). Ditto for XFS, JFS or
ext3.</para>
<para>Mondorestore will try to modify your /etc/fstab to reflect
changes you have made to the mountlist. If you are not using LILO,
you can still create your own /mnt/RESTORING/etc/lilo.conf and run
lilo -r /mnt/RESTORING to configure your boot sectors and Master
Boot Record.</para>
<para>Mondo (technically, Mindi on behalf of Mondo) creates a file
called a mountlist. This can be found on the ramdisk at
/tmp/mountlist.txt; it looks something like this:</para>

<para>This assumes that your old hard drive is /dev/hda and the new

<para>Or, if you want to add RAID support, create a new
/etc/raidtab on the ramdisk (which is beyond the scope of this
HOWTO) and then write a mountlist like this:</para>

<para>So long as your /etc/raidtab file is sane, Mondo can
automatically partition and format your disks for you, including
the RAID devices.</para>
<para>Once you have finished editing /tmp/mountlist.txt using
mondorestore's built-in editor then you may choose 'OK'. Please
note that this will not write anything to your hard disk. You will
only reformat or repartition your disks if you say 'Yes' when asked

<para>It is now possible to restore to a live filesystem using

<para><anchor id="AEN496"/>Q: What is "Mindi"?</para>
<para>A: Mindi, a.k.a. Mindi-Linux, makes a mini-distribution from
your kernel, modules, modules, tools and libraries. It can also
generate an El Torito 2.88MB boot disk image. Mondo uses Mindi to
create a mini-distro, then boots from it and runs on it.</para>
<para><anchor id="AEN501"/>Q: Why is it called "Mondo"?</para>
<para>A: The Teenage Mutant Ninja Turtles described cool things as
'mondo'. I wasn't sure what to call this project. 'Faust' was one
idea I had, partly as a dig at my former boss who practically owned
me because of my legal status at the time. In the end, I chose
something short and distinctive.</para>
<para><anchor id="AEN506"/>Q: Mondo does not work on my system. It
keels over and dies. What's wrong?</para>
<para>A: It works on Red Hat 7.x, Linux-Mandrake 8.x, some flavors
of SuSE, some flavors of Slackware, some flavors of Debian, etc.
The more distributions I support, the more moving targets I have to
hit. Please bear this in mind when e-mailing the list. :) If you
would like to help me by beta-testing Mondo (or Mindi) on your PC
then I would be very interested in working with you to work around
the eccentricities of your Linux distro. However, rest assured, 90%
of the bugs reported to me are actually symptoms of FooLinux X.Y's
unique way of doing things.</para>
<para><anchor id="AEN511"/>Q: What if the error is in Mindi?</para>
<para>A: Then send me a copy of /var/log/mindi.log (compressed,
please) along with a description of your distro, your kernel, etc.
Oh, and before sending it, please read it.</para>
<para><anchor id="AEN516"/>Q: Can I trust Mondo?</para>
<para>A: Mondo has generated reliable archives since May 2000. I
have lost data by using bad CD-R disks and not verifying their
contents. Some users have not tried booting from their CD until
crunch time. Remember to boot into Compare Mode to verify the
backup before you trust it. If Mondo did not work, you would not be
reading this. If it does not work for you, your kernel is usually
the culprit. Check <ulink url="kernelsupport.html">Linux Kernel
support</ulink> to see what your kernel should support. Please
e-mail the list (or me) if you need some help with this.</para>
<para><anchor id="AEN522"/>Q: How do I report a bug?</para>
<para>A: E-mail the bug report (mondo.err.xxxxx.tgz) to me. If you
want to discuss it, please e-mail the list. The list is for
talking; my e-mail address is for big files. :-) If you don't send
me a logfile then there isn't a lot that I can do for you, so
PLEASE include a logfile at the very least. Or, pop into #mondo on
irc.redhat.com and see if I'm there.</para>
<para><anchor id="AEN527"/>Q: I think Mondo should (...insert
suggestion here...) and I have rewritten it accordingly. Would you
like to see my patch?</para>
<para>A: Absolutely! :-) The best way for you to make Mondo do what
you want is to modify it and then send me the patch. That way, we
can all benefit.</para>
<para><anchor id="AEN532"/>Q: I think Mondo should (...insert
suggestion here...); will you incorporate this feature for me,
please?</para>
<para>A: I'll definitely think about it. Would you like to
help?</para>
<para><anchor id="AEN537"/>Q: Mondo says, "XXX is missing," and
then terminates. What's wrong?</para>
<para>A: A good Linux distribution should contain XXX but the
designers, in their infinite wisdom, decided not to include that
particular tool. Check <ulink url="linuxpackages.html">Related
Linux Packages</ulink> and install the missing package. If that
fails, contact the vendor/distributor/manufacturer/designer of your
distro.</para>
<para><anchor id="AEN543"/>Q: Can Mondo handle multi-CD backups and
restores?</para>
<para>A: Yes, up to twenty CD per set. This 20-CD limit results
from laziness on my part. I can remove it at any time. However, if
your system occupies more than 20 CD, may I recommend that you
invest in a tape streamer?</para>
<para><anchor id="AEN548"/>Q: Can Mondo handle Linux/Windows
dual-boot systems?</para>
<para>A: Yes. If your system currently boots into Linux or Windows
via LILO, you can backup and restore both OSes at the same time
using Mondo. If you are using NTFS then add the switch, '-x
&lt;device&gt;'.</para>
<para><anchor id="AEN553"/>Q: Can Mondo backup Windows-only
systems?</para>
<para>A: Sure, if you pay me to play catch-up to Microsoft. ;)
Seriously, Mondo can do it but I do not give away the
functionality. If you are a Microsoft-only user, you are accusomed
to paying for software and technical support. Please e-mail me for
more information.</para>
<para><anchor id="AEN558"/>Q: Does Mondo support LVM?</para>
<para>A: Mondo supports LVM, yes. Mondo backs up and restores your
existing setup but it does not make it easy for you to change your
LVM configuration. You have to edit /tmp/i-want-my-lvm at boot-time
to do that.</para>
<para><anchor id="AEN563"/>Q: What if I don't use LILO? What if I
use GRUB?</para>
<para>A: GRUB is supported by Mondo.</para>
<para><anchor id="AEN568"/>Q: Mondoarchive (or mondorestore)
segfaults when I run it. What could be wrong?</para>
<para>A: Install from tarball instead of RPM. (Or, try RPM if you
just installed from tarball.) Your compiler or your libraries may
be fubar. We'll see. If that doesn't work then please e-mail the
<ulink url="../../feedback/feedback.html">mailing
list</ulink>.</para>
<para><anchor id="AEN573"/>Q: I get the error, 'Cannot find
/tmp/dev.0' or 'Cannot mount device 0x0701'; what do I do?</para>
<para>A: Please free up /dev/loop0 using 'losetup /dev/loop0 -d' to
unmount that loop device. If your OS will not let you do that,
contact your local support group or Linux vendor.</para>
<para><anchor id="AEN578"/>Q: Can I create a Mondo CD and then use
it to create an archive of any OS on any PC?</para>
<para>A: Not yet. You can use Mondo to backup Linux or
Linux/Windows dual boot. One day, Mondo will let you backup
partitions it can't read or write, by treating each partition as
one long file to be backed up. This file will be chopped,
compressed and archived like any other big file.</para>
<para><anchor id="AEN583"/>Q: Why do you insist on putting floppy
disk images on Mondo CD? They waste space and I never use them. The
CD works just fine, so why keep the floppy disk images?</para>
<para>A: Because of my old college buddy, Justin Case. If you
really, truly want them gone then please submit a patch to make

<para>A: Try running it. :) That's always a good way to find out.
Check the <ulink url="../../docs/docs.html">Documentation
page</ulink>, too.</para>
<para><anchor id="AEN607"/>Q: When I try to boot from the Mondo CD,
it says, "VFS: Unable to mount root fs." I am using a Debian
distro. What do I do?</para>
<para>A: Ask Debian's designers why they, unlike every other distro
I can find, have included cramfs and other 'goodies' with their
kernel. In the meantime, please use '-k FAILSAFE' in your command
line when calling Mondo.</para>
<para><anchor id="AEN612"/>Q: When I try to boot from the Mondo CD,
it says, "Cannot mount root fs - kernel panic," or something
similar. What do I do?</para>
<para>A: Recompile your kernel (or use '-k FAILSAFE'). Take a look
at <ulink url="kernelsupport.html">Linux Kernel support</ulink> to
see what you're kernel must support.</para>
<para><anchor id="AEN618"/>Q: When I try to boot from the Mondo CD,
it says, "UPGRADE YOUR RAM". What does that mean?</para>
<para>A: Recompile your kernel and add Virtual memory file system
support. Take a look at <ulink url="kernelsupport.html">Linux
Kernel support</ulink> to see what you're kernel must support. (Of
course, if your PC has less than 64MB of RAM, you could always...
what's the phrase? I know, upgrade your RAM!)</para>
<para><anchor id="AEN624"/>Q: When I try to boot from the Mondo CD,
it says something about not finding my CD-ROM drive and then it
blames the kernel. What does that mean?</para>
<para>A: Your kernel must support initrd, loopfs, IDE CD-ROM's, and
ramdisks. Take a look at <ulink url="kernelsupport.html">Linux
Kernel support</ulink> to see what you're kernel must support. If
your kernel does not support these things, Mondo will not boot from
your CD. However, when running Mindi, you may choose to use _its_
kernel instead of your own. In addition, you may boot from floppy
disk images instead the CD: copy the disk images from the CD
/images directory to floppy disks, using 'dd'. Take a look at
<ulink url="faqbooting.html#COPYBOOTDATADISK">Copy boot data
disks</ulink> on how to make those.</para>
<para><anchor id="AEN631"/>Q: The Mondo CD/floppy takes ages to
boot. How can I speed it up?</para>
<para>A: Edit mindi (it's a shell script, btw) and change
LILO_OPTIONS="" to LILO_OPTIONS="-c". This enables map compaction
in lilo and speeds up booting, for more info see the lilo man
page.</para>
<para><anchor id="AEN636"/>Q: I made a Mondo CD using the failsafe
kernel (i.e. I said 'no' when Mondo asked if I wanted to use my own
kernel). It still doesn't boot. Help!</para>
<para>A: OK, now that is a bug. :-) I included a kernel with Mondo
(technically, with Mindi, which Mondo uses) to make sure that users
could use Mondo despite flaws in their own kernels. If you are
using Mondo/Mindi's kernel but still cannot boot from your Mondo CD
then please e-mail the list.</para>
<para><anchor id="AEN641"/>Q: What if my PC won't boot from a
CD?</para>
<para>A: Copy the image files from the CD /images directory, using
the dd command. Take a look at
<ulink url="faqbooting.html#COPYBOOTDATADISK">Copy boot data
disks</ulink> on how to make those. Then boot from the first
floppy; follow it up with the data disks; finally, type 'mount
/mnt/cdrom' and then utilize the restore script as usual, e.g.
mondorestore.</para>
<para><anchor id="AEN647"/>Q: But why won't Mondo boot from my CD?
It says my kernel is flawed/outdated/ whatever, and when I wrote to
you, you told me the same thing... but I still don't get it. I
mean, my kernel works for everything else. Why not Mondo?</para>
<para>A: Because Mondo makes a boot disk using your kernel. I bet
your other software doesn't do that. Also, not all kernels are
suitable for boot disks. I'm sorry but that's Life. Upgrade your
kernel and/or recompile it. Take a look at
<ulink url="kernelsupport.html">Linux Kernel support</ulink> to see
what you're kernel must support.</para>
<para><anchor id="AEN653"/>Q: Why do I only need a boot disk if I'm
using a tape drive? Where are the data disks?</para>
<para>A: On the tape. :-) The first 32MB of the tape will be set
aside for a large tarball containing the data disks, a list of all
files backed up, and other sundries. If Mondo and Mindi do their
respective jobs then you won't need additional floppies, just the
boot floppy and the tape(s).</para>
<para><anchor id="AEN658"/>Q: Why does it say, "Process accounting
FAILED" when I reboot?</para>
<para>A: You were using Process Accounting. Red Hat (or whichever
distro you are using) does not provide a startup/shutdown script
yet. So, when you try to backup the process log, it just grows and
grows as Mondo tries to back it up. Mondo doesn't back it up
anymore and that's why. The unfortunate side-effect is... well,
what you see on your screen. Type 'touch /var/log/pacct' and then
'paccton' to fix the error message.</para>

Some tape drives just suck, I'm sorry to say. If yours is one of
them then God help you. Mondo can handle any tape drive whose drive
and firmware can handle fread(), fwrite(), fread() and fclose().
Mondo uses standard C libraries to talk to your tape streamer. If
your tape streamer can't handle that then you had better call a
priest. Either that or ask for a refund.</term>

<para><anchor id="AEN822"/>Q: Can Mondo help me
move/resize/re-allocate my partitions?</para>
<para>A: Yes. Just backup your system in Interactive Mode using
Mondo. Edit the mountlist when prompted.</para>
<para><anchor id="AEN827"/>Q: My zip drive is a SCSI drive. When I
restore, Mondo craps out, saying it can't mount the drive (because
there is no disk in it). What do I do?</para>
<para>A: Restore in Interactive Mode. Delete the SCSI drive from
the mountlist before you restore. Then Mondo won't try to partition
or format it. Next time you backup, use -E /dev/sdd (or whatever
your zip drive is). The /dev entry will be excluded from the
mountlist but not from the filelist. So, when you restore, you
won't accidentally reformat your zip disk. However, after
restoring, you will find that /dev/sdd (the _file_) will still be
present in your /dev directory. Cool, eh?</para>
<para><anchor id="AEN832"/>Q: I received a message like, 'Fileset
NNN failed' during restore. What does it mean.</para>
<para>A: It usually means either you had a very large (&gt;2GB)
file which was not archived owing to a flaw in your distro or your
filesystem has changed in relation to the backup.</para>
<para><anchor id="AEN837"/>Q: Why does my ext3 partition have less
space free than when I backed it up?</para>
<para>A: Mondo creates a 10MB journal file area. Your journal was
probably smaller than that, hence the difference.</para>

booting from the CD/floppies, I sometimes get errors like, "Running
out of memory" or "Segmentation fault". What is going on?</term>
<varlistentry><term>A: It sounds as if you are running out of disk
space, probably ram disk space. Type 'df -m' to see which
partitions are running low on space. Please send as much
information as you can to the mailing list. This problem is
believed to have been fixed in 1.63 and 1.71.</term>

<para><anchor id="LVM"/>Q: I can't nuke-restore my LVM or RAID or
LVM-on-RAID setup. I have to do it manually. What now?</para>
<para>A: You said it yourself. You have to do it manually. :) Sorry
but that's about it. At least you have all the tools to do it. I
assume you know how. If you don't, look at i-want-my-lvm (a script
on the ramdisk) if you're using LVM. It should give you a few
clues. RAID is harder but in general Mondo's RAID support is good.
After you've prepped and formatted your drives, run mondorestore
again but say 'no' when asked if you want Mondo to prep or format
your drives.</para>
