Problems mounting logical volumes

Hi,

I have a similar problem to one i found in the archive:
http://linux.msede.com/lvm_mlist/archive/2002/09/0097.html
with a few difference though.

I tried to adoped the steps recommended to my setup but still wasn't able to mount the lv. Basically because of the superblock error mentioned.

goliath:/usr/src # mount -t ext3 /dev/goliath_vg/moviez /home/Moviez/
mount: wrong fs type, bad option, bad superblock on /dev/goliath_vg/moviez,
or too many mounted file systems

Some things about my system. I am using SuSE 8.0 with kernel 2.4.18(-suse) and lvm 1.0.2 (at least this is what it says at boot time).

I set up lvm about two weeks ago. The actual setup will follow at the end of this mail. What gets me concerned is the Status of the PV (/dev/hdd1) wich is 'NOT available' while it is in the posting mentioned above.

What I've tried so far is to mount the lv with the backup superblock option. But I'm not sure how to figure out what blocks are backups of the superblock. The ext3 inside the lv has a blocksize of 1k according to 'man mount' superblocks were stored every 8192 block but aren't anymore. Because I got 1k block instead of 4k I tried to mount the lv with

goliath:/usr/src # mount -t ext3 -osb=32768 /dev/goliath_vg/moviez /home/Moviez/

mount: wrong fs type, bad option, bad superblock on /dev/goliath_vg/moviez,
or too many mounted file systems

rather then 131072 as well as several other blocks but none of them worked (How do I actually figure out which blocks are superblocks).

Some more information that migh be usefull. tune2fs produces the following output:

goliath:/usr/src # tune2fs -l /dev/goliath_vg/moviez tune2fs 1.26 (3-Feb-2002)

and fsck.ext2/3 end up in a segmentation fault

goliath:/usr/src # fsck.ext2 /dev/goliath_vg/moviez e2fsck 1.26 (3-Feb-2002)
Group descriptors look bad... trying backup blocks... Segmentation fault

Because of the 'Group descriptors look bad' I tried to restore the vgs metadata by doing a vgcfgrestore with all the backups I had (Not sure what the Group descriptors actually are but because it is a lv I thought it might the vg Group...). Neither of the backups would solve the Group descriptors thing.

I am out of options and would be rather thankfull for any advice on howto mount the lv and save the data contained.

regards and thnx in advance for any help
