Re: [Xen-users] how to run fsck for a crashed domU?

["Rudi Ahlers" <Rudi@xxxxxxxxxxx>]

What do I use if I don't have X / KDE installed? Can I run kpart without X?

Kind regards

okay, I got it now...

step by step...

1. losetup /dev/loop4  /home/vm/vm01.img
# This mounts the image file as imaginary physical to /dev/loop4

2. kpartx -va /dev/loop4
# This creates a device map with partitions in vm01.img in /dev/mapper

3. vgscan
# This should discover your lvm VGs from Image.

4. lvscan
# Should list the ACTIVE  volumes.

5. Now you can do e2fsck to the volumes listet by lvscan.
But be sure to e2fsck only the LVs from yout Image if you're using lvm 
in Dom0, too.

Please give feedback if this worked for you.


Cheers,
Alex
