LVM: Resque
 
Hi,

I have the following problem:
I cant mount my lvm
My lvm consists of the following:
fsx02:~ # lvm pvscan
File descriptor 4 left open
PV /dev/sda1 VG jackal lvm2 [232.88 GB / 0 free]
PV /dev/sdc1 VG jackal lvm2 [232.88 GB / 48.00 MB free]

Both partitions are ext3
Mount cant determine the filesystem type. And fsck gives:
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sdc1

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:


I need that data on those partitions. What can I do?
I have numerously created and deleted the volume groups.. to no avail.

If I could somehow convert the partition back to plain normal ext3 mount it, backup it and then redo the lvm.. it would be great.. is that possible?

Plz! All ideas welcome!

What is the output of `lvscan`?

I've managed to recover 40GB. I had to fsck.ext3 on the lvm using the last backup superblock as a reference. It worked and I lost quit a lot of stuff.. but nobody is dead so it's ok.

Tx for the reply. I think this is a bug in kubuntu installer.
