 |
|
Hi all,
I'd like to do a bootable backup of my "gentoo" laptop. It seems that mondo + mindi are a perfect match for this task. I experienced it with success on an RH7.3 server. But on my laptop, I have some problems. Here is the log :
| Code: |
hansolo root # mondoarchive -Oi -d /backup -E "/backup /tmp"
Initializing...
Mondo Archive v1.47 --- http://www.mondorescue.com
----------------------------- ls -l /backup -----------------------------
total 0
--------------------------------end of output------------------------------
------------------------------ insmod dos ------------------------------
insmod: dos: no module by that name found
--------------------------------end of output------------------------------
...ran with errors.
------------------------------ insmod fat ------------------------------
insmod: fat: no module by that name found
--------------------------------end of output------------------------------
...ran with errors.
------------------------------ insmod vfat ------------------------------
insmod: vfat: no module by that name found
--------------------------------end of output------------------------------
...ran with errors.
---------------------- grep vfat /proc/filesystems ----------------------
--------------------------------end of output------------------------------
...ran with errors.
-------FATAL ERROR---------
Either call mondoarchive with '-o', or recompile your kernel to include VFAT support.
Author can and will render assistance only to users who include a gzipped copy
of /var/log/mondo-archive.log and /var/log/mindi.log in their bug report.
(Or /tmp/mondo-restore.log if it is a restore-time problem)
Please read the FAQ and the logs before you e-mail the mailing list.
FYI, I have gzipped the log and saved it to /tmp/MA.log.gzMondo has aborted.

I recompiled my kernel to enable ramdisk support, seems to be ok:
| Code: |
hansolo root # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda4 8.1G 4.0G 4.2G 49% /
tmpfs 2.0M 156K 1.9M 8% /mnt/.init.d
tmpfs 62M 0 62M 0% /dev/shm
|
but still, mondo + mindi do not work, seems still to search something like ramdisk in /proc/devices.
Does some soft link is missing ? any idea ?
Thanks for your help.

I'm not sure, but the following link maybe useful: http://koto.mynetix.de/gentoo/
I'm having some problems getting Mondo up and running as well, but I may have something useful... I had problems getting the RAM-disk to work, but that was because I have a strange setup where I thought I'd moved my /boot when adding some IDE drives on a PCI controller when I have a SCSI boot - in fact I kept copying the new kernels to the wrong place. I got it working, but one thing that may be of use is that I initially left the RAM disk with the default size, but later increased it, and when I got it working it was something like 64MB (easy when all my PC's currently have 512MB). That may be something to try, or other settings in the kernel. BTW I built it in rather than as a module. |

Ooops, I must confess I didn't post a follow-up of my problem in this forum since there were not so much interest in this thread. You remind me that it could help others.
Here's the experience. I took my problems to the mondo-devel mailing list (very active, very supporting, bravo) and found all the mandatory kernel features. In the past, and for the fun of it, I managed to build a very "slim" kernel, but to have mondo working I had to add these options :
- ram disk support
- initrd ramdisk support
- vfat
- fs loopback
et voilà ! mondo/mindi works fine. It seems that mondo devel team also tooked some gentoo specific behavior for their next release. for instance, the fact that gentoo unmount /boot when getting to init level 6 will no more prevent mindi/mondo to properly burn your kernel.
at this stage you still have to manually mount your /boot partition and specify the path to your kernel to have mondo working. something like mondoarchive -Oi -d /dev/xxx -k /boot/bzImage ...
hope this helps. |

It's good to hear you have it all working. 
The current problem I have is with Mindi finding the size of my software RAID array. I've been looking in a few places and not found a lot (other than for the restore process which I doubt is relevant). I expect that once I'm back at my Gentoo box I will join the mailing list to see how it can be fixed!
It seems like a good idea to build a special kernel just for mindi/mondo - I think I'll try that sometime! |
