vgck seg faulting]

Does anyone beleive that running a tool such as gpart or rescuept would help recover the missing superblock and allow me to mount the logical volume?

Since the actual device /dev/vg0/logical0 actually gets created is it safe to assume that all LVM metadata is intact and correct and my problem is with the filesystem, not the lower level LVM?

Thanks,

I recently replaced a failing drive in my lvm1 volume group by doing a dd from the bad drive to a new drive. However after a few days I can no longer mount the logical volume. When I try to the mount the volume I get this output:

mount: wrong fs type, bad option, bad superblock on /dev/vg0/logical0,
or too many mounted file systems

I have a feeling that the superblock is corrupt.

I tried running vgck, but it seg faults after a point:

vgck -v
vgck -- locking logical volume manager
vgck -- finding all volume group(s)
vgck -- checking volume group name "vg0"
vgck -- checking existence of volume group "vg0"
vgck -- reading volume group data for "vg0" from lvmtab vgck -- checking volume group consistency of "vg0" in lvmtab vgck -- VGDA of "vg0" in lvmtab is consistent
vgck -- reading volume group data for "vg0" from physical volume(s) Segmentation fault (core dumped)

Can anyone help me get this mounted again?

thanks,

Bernard Zolp
