Mondo on SLES9 / Problems with Restore

Hi,

I am trying to set up mondo on 2 new servers, both with SLES9/SP4.

Everything seems to run fine when doing backup, but when I try to restore, I get an error in the partition
table dialog that my ext3 and reiserfs are not supported.

I found out that the modules for ext3, jbd and reiserfs will not load on boot from the Mondo restore CD.

I included my log files from the last backup. Did anyone else encounter this problem or knows what is going
wrong ?

I installed the following from the mondo ftp server:

rpm -Uvh mindi-busybox-1.7.3-1.sles9.i586.rpm 
rpm -Uvh mindi-2.0.3-1.sles9.i586.rpm 
rpm -Uvh afio-2.4.7-1.i386.rpm 
rpm -Uvh buffer-1.19-1.i386.rpm 
rpm -Uvh newt-0.51.6-10.i386.rpm 
rpm -Uvh mondo-2.2.6-1.sles9.i586.rpm 

Best regards,
Marco

Is Mondo Restore on DVD + Grub = Not-Bootable?

Hi,

I have spent the better part of the month trying out Mondo Backup and
Restore from DVD. I have tried 3 scenarios, all of which have failed.

Scenario-1: From Fedora Core 8 to a New Machine

On Fedora Core 8, I did a yum install mondo following the instructions at
wiki. Then, I typed "mondoarchive". A GUI popped up, asking various
questions. I selected DVD, backed up "/" and excluded nothing.

Mondoarchive reported backuo be complete successfully. I now detached the
DVD Drive with the DVD inside it, attached the DVD drive to another
machine, started the new machine, and typed "nuke" at the prompt. I also
allowed the program to automatically configure the grub. The program
reported success. Then, when I removed the DVD and restarted the computer,
grub found fedora, and while starting the kernel, threw the error:

mount: could not find filesystem /dev/root"

I was not able to overcome this problem

*************************************************************************

Scenario-2: From Ubuntu to a New Machine

On a machine that had ubuntu-8.04-Desktop-i386.iso, I typed:

#sudo apt-get install mondo,
#mondoarchive

did the same as before, and tried the DVD on the new machine: - The
restore in nuke mode was apparently successful according to mondorestore,
but when I restarted the new machine, I got a boot error and was dropped
into "initramfs" shell. There was apparently some confusion between hda
and sda - mondo thought hda was the right assignation but ubuntu would
think it was sda. Anyway, I could not get over this problem either ....

*************************************************************************

Scenario-3: From Ubuntu to SAME Machine

Reasoning that the hardware differences might account for strange mondo
behavior, I tried nuking the same machine that I had created the Mondo-DVD
(ubuntu machine). It gave the same problem as scenario 2!!!

*************************************************************************

One common factor has been GRUB in all my tests. I've read Hugo Rabson's
mentioning GRUB has been a difficult thing to get to work with mondo.
Could that be the problem that I am seeing? Has anyone else been able to
do a mondoarchive and nuke-restore with current versions of mondo?

I will appreciate any tips and pointers regarding what I am doing wrong.

Thanks,
Srikanth.

Re: Is Mondo Restore on DVD + Grub = Not-Bootable?

hi,

perhaps this could help you...

i use mondo for all my server in redhat ES 4
on some server (i don't know why) when i try to restore , after the 
operation (all is all right) but when the server reboot i have this 
message from grub :"grub loading stage 1.5" and freeze on this..

so this is how i correcte it:

-boot in rescue mode
-mount your file system in /mnt/sysimage (normaly it is automatic with 
fedora in rescue mode)
-when you got prompt type : chroot /mnt/sysimage
-type grub
-in grub type :root (hd0,0)
(hd0,0) is your first HD ,and your first partition that contain
you /boot
-type :setup (hd0)
(that will reinstall grub on this partition)
-type :quit
-reboot

for me this works but i don't know if you have the same probleme

good luck, mondo is wonderfull (excuse my poor english i'm french...)

2.2.6 Bugs

HI!

I was trying 2.2.6 on Gentoo and found 2 problems, when running 
mondorestore from a booted system:

1.
It cannot read iso files from 2.2.4.

2.
When I make no selection and choose cancel, it frees memory and then 
restores everything!

Thomas

You don't need to exclude /proc it's done by default.

Yes. You may increase the size of the image for real DVD (up to 4380m)

> - why do i need 2 images ?

One is from mindi and is provided as a convenience (under
/var/cache/mindi). The one you really want is under /rescue

Well -9 is passed to gzip/bzip2 that way. 
bzip2 gives the best compression ratio at the expense of time (both at
backup and restore).
gzip -6 gives IMHO the best average.

Try launching mondoarchive in CLI mode with -S and -T options to force
the location of temp files which seems to create a pb for you.

Re: disk full error

david said on Sat, Jul 12, 2008 at 02:08:26PM +1000:

> Ubuntu Hardy. Mondo Version: 2.24-2

You may want to look at 2.2.6 upstream packages as well.

> I ran this command:
> 
> root <at> host:~# mondoarchive -O -i -N -d /root/images/mondo -m -s 4G -F -K
> 99

You may want to  add a -S/-T to force temp files to another location
than the default which may be an issue in your case.

> The Archive run fails with a "disk full" error after 50% of the run.
> The disk isn't full.

Generally its linked to the use of /dev/shm for tmpfs in mondo:
> 
>         root <at> host:~# df
>         /dev/shm                358400         0    358400
>         0% /var/run/tmp.mondo.17672/tmp.mondo.10604/tmpfs
> 
> Log files attached, but the error message from the log seems to be:

Yes just before that:

[Main] libmondo-archive.c-≥_move_files_to_cd#2752: (move_files_to_cd)
'mv -f /var/run/tmp.mondo.17672/tmp.mondo.10604/tmpfs/191.afio.bz2
/var/run/mondo.scratch.14466/mondo.scratch.17225/archives/' failed

So your /var/run may well be full at some point (mondo cleans stuff when
leaving).

If the -S/-T stuff isn't sufficient, please report back again.

Bruno.
