Hello,
A few days ago my system crashes and ive used LVM v 0.8 with one volume
group(server), two physical volumes(hda6, hdb6) and one logical
volume(dev/server/ftp)
Now ive installed Suse 7.2 with LVM v 0.9 Beta7, but i cant mount the
logical volume.
The error message is:
# mount /dev/server/ftp /mnt
mount: wrong fs type, bad option, bad superblock on /dev/server/ftp,
or too many mounted file systems
I get the following outputs from my system:
# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "server"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group
# pvscan

# vgchange -ay
vgchange -- volume group "server" already active
# lvchange -ay /dev/server/ftp
lvchange -- logical volume "/dev/server/ftp" is already active
lvchange -- availability of logical volume "/dev/server/ftp" doesn't
have to be changed
lvchange -- logical volume "/dev/server/ftp" didn't have to be changed
Ive tried to follow the instructions of the mailing list article, ive
found at http://www.geocrawler.com/archives/3/3500/2001/4/0/5655568/
But it doesnt work, After vgchange ay I get an error message, too,
like
vgcfgrestore -- ERROR: different structure size stored in
"/etc/lvmconf/export.conf"
than expected in file vg_cfgrestore.c [line
> 120]
> vgcfgrestore -- ERROR "vg_cfgrestore(): read" restoring volume group
"export"
I hope you can help me,
Thanks
Christoph
