Hi.
The problem I had here two days ago were almost fixed by the beta4
release. I am still not quite aware of how to make sure this would work
properly. See output below.
This behaviour is although different from what I saw using beta2, but the
problem is still here. :(

Resent-Subject: [linux-lvm] Weird corruption of volume group configuration
with LVM.
Hi,
After rebooting my system a couple of days ago, I ran into a real strange
problem with the volume group "mw1" I am using.
Doing a vgscan locates no volume groups what so ever.
After doing a `vgcfgrestore -f /etc/lvmconf/mw1.conf -n mw1 /dev/<DISK>`,
I am able to do a `vgchange -a y`, and actually mount /dev/mw1/ftpd.
Doing a vgscan at this point locates no volume groups either.
This means that I can't mount the volume group automatically during
bootup, neither can I use any of the vg* commands in the system. I am just
able to use the volume group as it is, for data storage, without any
possibility to use the LVM features.
I tried to reboot the system, used vgcfgrestore to re-add the
configuration to the disks, and do a vgcfgbackup after that. It produces
the following (with -v):
vgcfgbackup -- finding all volume groups
vgcfgbackup -- volume group found: mw1
vgcfgbackup -- locking logical volume manager
vgcfgbackup -- checking volume group name "mw1"
vgcfgbackup -- checking existence of volume group "mw1"
vgcfgbackup -- ERROR: volume group "mw1" has an invalid number of physical volumes
vgcfgbackup -- ERROR "vg_cfgbackup(): vg_check_exist" backing up volume group "mw1"
Output from pvscan:
pvscan -- reading all physical volumes (this may take a while...)

I hope you see what my problem is, otherwise, tell me what output that
would be needed, and I'll provide it.
Thank you.
