[linux-lvm] lvm1.0.8: vgcfgrestore does not seem to work

[Stefan Lucke]

Hi, I know I'm running an old system, but yesterday I got some troubles.
It started with a simple read I/O error on an lvm disk. There are 2 x 300GB
disks in that VG. Next step was that first 8 sectors were zeroed on the first
disk in that VG. pvscan showed only the 2nd of this VG and disks of other
VGs. Doing a: 
./vgcfgrestore -ll -n vg01 -v -f /etc/lvmconf/vg01.conf  /dev/sde
shows expected values for this VG:
vgcfgrestore -- locking logical volume manager
vgcfgrestore -- restoring volume group "vg01" from "/etc/lvmconf/vg01.conf"
vgcfgrestore -- checking existence of "/etc/lvmconf/vg01.conf"

vgcfgrestore -- unlocking logical volume manager

but a subsequent vgscan only finds my other VG

Hopefully I havn't lost the entire video data :-( .
Really need some advice.

Ah, grr. option -l is somthing like a test option in addition to -t. 
Dropped those -l or -ll and vgcfgrestore did what it was expected to do.
My volume group is back online :-)))  .
