I am running SuSe 7.1
2.4.0 kernel
512M Ram
AhA2940U2W
suse lvm
I had three volume groups and a week ago the volume group that contained user
had a drive crash. I was unable to save usr but now I can not mount any of
my other volume groups and vgcfgrestore fails. Is their any thing I can do
to get my data?

No joy on this on this method.
If you need I can supply more inforamation.
BTW I am running on an Athlon..

You are using a newer LVM versions which has different metadata definitions
that the one which created those backups.
My guess is, that you are using LVM > 0.9.1 Beta 3 *now* but created the
backups with a lower LVM 0.9 version and you suffer from a PV uuid related
bug preventing vgscan to find your VG.
One way to address the situation (pressuming no VGs are active) is:
- create /etc/lvmtab.d/ in case it doesn't exist
- copy /etc/lvmconf/export.conf to /etc/lvmtab.d/export
- echo -ne 'export\0' > /etc/lvmtab
- vgchange -ay
If the VG named "export" comes back to life this way (assuming that the user LV
belongs to it) do:
- lvreduce -l1 /dev/export/user
- lvrextend -l1 /dev/export/user
replace "user" with a valid LV name in case I assumed wrong.
The purpose of that NULL operation in the end is, that your PV uuid list
gets recreated by LVM >= 0.9.1 Beta 4 which should make vgscan happy again ;-)
The last 2 commands just shrink user by 1 LE and grow it again which
is necessary, because your export VG is *full*. This will not harm the user
LV in the end, because the allocator has the only option to use the very same
PE for growing which was freed before by the shrinking of user.
If your VG had at least 1 free PE a lvcreate/lvremove cycle for a dummy
LV with just 1 LE had done it as well.
Please tell us if this helps you or we need to go for another solution.

Ok, I have my volumes back.
It was messy but it worked.
l simply removed the lvm 9.4 and reinstalled lvm 8.0
I then did the vgcfgrestore and opt and export came back.
thanks for your help.

That was another option ;-)
Have you beann able to upgrade to LVM 0.9.1 Beta 7 already, run some changing
command and did everything work fine?
If not so, I'ld be very interested in it.
