Hi,
I was running lvm with one PV [/dev/hdb3], making up one GV
[/dev/data], which was completely allocated to one LV
[/dev/data/homes]. My root was a separate harddisk [/dev/hda1]. Hda is
now gone, and so is my /etc, where my VGDA was.
Is there a way for me to get at the data that is still stored on
/dev/hdb3 (I am running slackware linux 9; linux-2.4.20, lvm-1.0.6)?
When I run pvscan I get the following:
root@ved:~# pvscan -v
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- walking through all physical volumes found
pvscan -- inactive PV "/dev/hdb3" is associated to unknown VG "data"
(run vgscan)
pvscan -- total: 1 [13.64 GB] / in use: 1 [13.64 GB] / in no VG: 0 [0]
This suggests I run vgscan...
root@ved:~# vgscan -v
vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d"
vgscan -- creating empty "/etc/lvmtab" and "/etc/lvmtab.d"
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- scanning for all active volume group(s) first
vgscan -- reading data of volume group "data" from physical volume(s)
vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of
volume group "data" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group
...
vgimport segfaults on me when I try to import the VG as shown:
root@ved:~# vgimport -fv data /dev/hdb3
vgimport -- locking logical volume manager
vgimport -- checking volume group name
vgimport -- checking volume group "data" existence
vgimport -- trying to read physical volume
vgimport -- checking for duplicate physical volumes
vgimport -- checking physical volume name "/dev/hdb3"
vgimport -- reading data of physical volume "/dev/hdb3" from disk
vgimport -- checking for exported physical volume "/dev/hdb3"
vgimport -- checking consistency of physical volume "/dev/hdb3"
vgimport -- reallocating memory
Segmentation fault
"pvdata -P /dev/hdb3" yields

Any help will be greatly appreciated. I am still sifting through the
linux-lvm archive, but I can't seem to find a case that resmbles mine
closely enough...
Thanks,
