56 <A NAME="AEN822"></A><B>Q: </B>Can Mondo help me
57 move/resize/re-allocate my partitions?</P>
58 <P ALIGN=LEFT>
59 <B>A: </B>Yes. Just backup your system in Interactive Mode using
60 Mondo. Edit the mountlist when prompted.</P>
61 <P ALIGN=LEFT>
62 <A NAME="AEN827"></A><B>Q: </B>My zip drive is a SCSI drive. When I
63 restore, Mondo craps out, saying it can't mount the drive (because
64 there is no disk in it). What do I do?</P>
65 <P ALIGN=LEFT>
66 <B>A: </B>Restore in Interactive Mode. Delete the SCSI drive from the
67 mountlist before you restore. Then Mondo won't try to partition or
68 format it. Next time you backup, use -E /dev/sdd (or whatever your
69 zip drive is). The /dev entry will be excluded from the mountlist but
70 not from the filelist. So, when you restore, you won't accidentally
71 reformat your zip disk. However, after restoring, you will find that
72 /dev/sdd (the _file_) will still be present in your /dev directory.
73 Cool, eh?</P>

75 <A NAME="AEN832"></A><B>Q: </B>I received a message like, 'Fileset
76 NNN failed' during restore. What does it mean.</P>
77 <P ALIGN=LEFT>
78 <B>A: </B>It usually means either you had a very large (&gt;2GB) file
79 which was not archived owing to a flaw in your distro or your
80 filesystem has changed in relation to the backup.</P>
81 <P ALIGN=LEFT>
82 <A NAME="AEN837"></A><B>Q: </B>Why does my ext3 partition have less
83 space free than when I backed it up?</P>
84 <P ALIGN=LEFT>
85 <B>A: </B>Mondo creates a 10MB journal file area. Your journal was
86 probably smaller than that, hence the difference.</P>

92 What is going on?</P>
93 <P ALIGN=LEFT>
94 <DT CLASS="mvd-P"><B>A:</B> It sounds as if you are running out of
95 disk space, probably ram disk space. Type 'df -m' to see which
96 partitions are running low on space. Please send as much information
97 as you can to the mailing list. This problem is believed to have been
98 fixed in 1.63 and 1.71.</P>

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