[linux-lvm] Problem: "only found 768 of 769 LEs for LV /dev/vg00/lvol1"

[linux-lvm] Problem: "only found 768 of 769 LEs for LV /dev/vg00/lvol1"

[Julian Glashoff]

Hello,

I have a problem with my volume group:
I was using kernel 2.4.7 with LVM 1.0.1-rc1.
I tried to extend a logical volume (/dev/vg00/lvol2) by 4Gig and got the
error message "No such device or address in kernel".
Then I tried to extend /dev/vg00/lvol1 by 1 extent just to test if I was
able to change volumes at all whereupon the system completely crashed.
On the next reboot I got the following message from vgscan:
-------------------------------------------------------------------
# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "vg00"
vgscan -- only found 768 of 769 LEs for LV /dev/vg00/lvol1 (1)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get
data of volume group "vg00" from physical volume(s)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" creating
"/etc/lvmtab" and "/etc/lvmtab.d"
-------------------------------------------------------------------
And now I am unable to access the volume group.
Then I tried to restore the backups with the following result:
-------------------------------------------------------------------
# vgcfgrestore -n vg00 -l
vgcfgrestore -- ERROR: different structure size stored in
"/etc/lvmconf/vg00.conf" than expected in file vg_cfgrestore.c [line 120]
vgcfgrestore -- ERROR "vg_cfgrestore(): read" restoring volume group "vg00"
-------------------------------------------------------------------
The documentation says this would be caused by an incorrect LVM version.
I was using 1.0.1-rc1 and have tried to restore the backups with every
version from 0.9.1-beta1 up to 1.0.1-rc2 and all versions give me the same
error.

Is there anything I can do to restore my volume group?

The output of "pvdata -a" can be found here:

Could you tell me which release of LVM you used to create the volume
group in the first place please ?
