Hi all!
My lvm-system crashed a day ago and I was really lost in how to do. Buy I found the metadatafile and could with
pvcreate --uuid ... --restorefile ... .... /hdg5,
pvcreate --uuid ... --restorefile ... .... /hdi1,
restore those two drives. It didnt work with just /hdg/hdi as the metafile decribes. hde couldn't be fixed with the restoredfile command, it said that it was to small or equiv, so I just did a pvcreate --uuid ... /hde1
my lvm version is 2.00.29.
After this I did the vgcfgrestore from the metadatafile, my_volume_group, which worked fine, and finally I hade to do a vgmknodes my_volume_group which also worked fine. But then when I tried to the lv I get this
roth:/dev# mount /dev/my_volume_group/mylv /disk
/dev/my_volume_group/mylv: Invalid argument
mount: you must specify the filesystem type
roth:/dev# mount -t ext2 /dev/my_volume_group/mylv /disk
mount: wrong fs type, bad option, bad superblock on /dev/my_volume_group/mylv,
missing codepage, or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
so I tried to fsck it but nothing worked. What have I done wrong? How can I get back my data?
I'll paste some shelldumps as help.
Regards
Daniel
