[linux-lvm] Remount a LVM Vol after a system crash



Hello,

A few days ago my system crashes and i’ve used LVM v 0.8 with one volume group(server), two physical volumes(hda6, hdb6) and one logical volume(dev/server/ftp)

Now i’ve installed Suse 7.2 with LVM v 0.9 Beta7, but i can’t 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

 

 

I’ve tried to follow the instructions of the mailing list article, i’ve found at http://www.geocrawler.com/archives/3/3500/2001/4/0/5655568/

But it doesn’t 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
