Mondo restore failure

[hugu]

I'd like to restore a mondo NFS backup but it fails with last message :

sh:can't access tty;job control turned off

The platform is : IBM blade HS21 on RHEL5

Versions : mondo-2.2.5-1.rhel5, mindi-2.0.1-1.rhel5, mindi-busybox-1.7.3-1.rhel5

[Bruno Cornec]

Problems were fixed on 2.2.5 for NFS support with RHEL5. Could you try with the latest 2.2.6 which was just made today !

TIA, Bruno.

I get the same error message with mondo 2.2.6 version.

I will try on CD to see if the pb really lies on NFS (I can find some warnings in mondoarchive.log)

Thanks, Hugu

You're still using mindi 2.0.1 and not the latest mindi 2.0.2. THat may explain some of the problems with 2.2.6.

Also what hardware do those lines support: i5000_edac 12481 0 edac_mc 26257 1 i5000_edac

? They are not supported by mindi as of now. Can you also provide your /var/log/mondorestore.log file And a picture of what happens before the one you attached (Shift PgUp to go back in screen history)

[hugu]

i5000_edac seems to be for

Intel 5000(P/V/X) class Memory Controllers kernel module

I've upgraded to mindi 2.0.2.

NFS restore : failure (still the same problem)

CD restore : failure with lot of messages "/sbin/init: line xxx: mount: not found" but network is OK. I have no way to get easily mondorestore.log or other screens. It could be useful that busybox provides a simple way (ftp, rcp) to push data elsewhere.

Which way to continue ?

[hugu]

NFS restore: first problem

[hugu]

NFS restore: last screen

I've just updated attachments after upgrades to mondo 2.2.6 and mindi 2.0.2

PXE parameters

[Bruno Cornec]

the nfsmount parameter of your PXE setup is incorrect. It should be nfsmount=194.214.218.85:/path/to/the/nfs/mount or nfsmount=194.214.218.109:/export/mondorescue as in the original backup

[Bruno Cornec]

Have you had time to confirm tht this is now solved ?

Hi, I seems to have the same issue during the restoration process, after making a successfully backup of Virtual Host based on centos 5 OS.

Note : The NFS files system where iso images are located is correctly mounted by "mindi" during the boot of the PXE restore process.

Here is my configuration :

Linux rhcsmgt 2.6.18-53.el5 #1 SMP

mondo-2.2.6-1.rhel5 mindi-2.0.2-1.rhel5 mindi-busybox-1.7.3-1.rhel5 deps : afio-2.4.7-1.rhel5 buffer-1.19-1.rhel5

Please see my attached pxelinux.cfg config file.

Hi,

After checking the content of initrd generated by mondo it seems to missing some libraries and some binaries comparing to the content of the file /etc/mindi/deplist.txt.

for example, mondorestore and "attached" libraries are missing so the script "post-init" cannot be correctly executed.

So when i add them manually (missing binaries and libaries) in initrd the process can continue.

I don't know why all items (libraries and binaries) listed in /etc/mindi/deplist.txt file are not present in initrd generated by mondo ?

best regards.

[Bruno Cornec]

The initrd doesn't contain everything. The rest is taken from the backup media. So the initrd only provides what is needed to mount that media (NIC driver + NFS + ext2/3,xfs,resierfs,... cdrom, ...loop)

As long as you cannot mount that ISO image, your restore is failing.

What's in your /var/log/mondorestore.log ?

[nbarthelemy]

Hi,

I supposed this because i have the same behavior when i use a USB key as archive media. Altough when i use a DVD as backup media the initrd.img contains mondorestore binary and all dependencies libraries.

/var/log/mondorestore.log file is located on the client machine called mondotest. I can't send it to you, because i can't mount any file system thrue nfs. When i try to mount nfs file system coorectly exported from my server, the client kernel answer "RPC failed to contact portmap" in /var/log/messages file on my mondotest machine. I can see the request on my NFS server log file.

I will try again tomorrow.

Despite correction on PXE setup suggested by Bruno on 06/17/08, problem still remains. Mondo-restore-pb.20080828.jpg gives the beginning of problems.

Please update first mindi to its latest version 2.0.3 and redo your backup, extract the content to your PXE server and report back again please.
