[linux-lvm] Mounting Reiserfs errors

[Laurentiu Simion]

I am running LVM with ext3 and recently with Reiserfs on Mandrake 8.1
(kernel 2.4.8-26) I had no problems for quite a time with ext3 but when
I have tried to play with Reiserfs I've got into big big trouble.

This is the /proc/lmv/global listing:

The VG with problems is "depot". Is split on 2 disk partitions and has
one LV using half of the space.
I was able at the beginning to mount /dev/depot/lvol1 as reiserfs but
after a FS resize I've got the following error trying to mount the FS:

# mount -t reiserfs /dev/depot/lvol1 /u0
mount: wrong fs type, bad option, bad superblock on /dev/depot/lvol1,
       or too many mounted file systems

I was running all the possible checks on /dev/depot/lvol1 as per below:

# reiserfsck /dev/depot/lvol1

I forced a FS repair but it will not repair. It seems there are no major
corruptions on the FS, but I cannot mount.

# reiserfsck /dev/depot/lvol1 --fix-fixable

I have upgraded the LVM module to 1.0.1.-rc4 in a 2.4.18 Kernel, but
nothing is changed.

Can somebody show me light at the end of the tunnel PLEASE?

Thanks in advance,

Laurentiu
