Re: [Xen-users] Resize DomU partition

[KC LO <kclo2000@xxxxxxxxx>]

Hi ,

Thanks for your reply!
However, I got the following errors on the first command

e2fsck 1.39 (29-May-2006)
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/VolGroup00/vm3

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

I guess that the file system is ext3 which got this problem.  Any hints?
