Hi!

I'm using LVM 0.9.1_beta7 on SuSE Linux 7.2.

I created a second VG (the other VG is detected by
vgscan on bootup) with only one PV and added some LV
to it. Later I added a second PV to the second VG and
i copied the old LV to new LV with stripes=2. All this
configuration was made with the lvm tool included in
yast from SuSE.
During reboot the system finds the first VG, but not
the second one, which was detected before, when only
one PV was assigned to it. I was using the second VG
before reboot with two assigned PV. 


*** output, which might be of interest:

Is there any way to fix the PV on hda2? I tried a tool
called uuid_fixer, but i only got the output "Illegal
instruction" back.

Michael,

the pvdata output below exposes a completely messy PV structure,
which makes me think of 2 possible reasons:

a. /dev/hda2 is not the device you used to create a physical volume

b. something accidentially overwrote /dev/hda2 after the PV creation


If b is true you might still have an actual VGDA backup in /etc/lvmconf/ which
you can use to vgcfgrestore(8) it to /dev/hda2 presumed that /dev/hda2 is
the right device.

Heinz    -- The LVM Guy --

I already tried vgcfgrestore. All available backup files lead to the
same result:

My idea was to reset the values of /dev/hda2 according to the following
settings:

These values seem plausible for me. Can i use them to manually edit the
PV /dev/hda2 to rescue some data?

List members:

	It might be worth adding to the How-To that no initscript modifications are necessary for Linux Mandrake, as their default rc.sysinit script contains code in it to do the vg initialization on boot up.

These values seem plausible for me. Can i use them to manually edit the

	It might be worth adding to the How-To that no initscript modifications are
necessary for Linux Mandrake, as their default rc.sysinit script contains
code in it to do the vg initialization on boot up.

And Debian initscripts are taken care of if you "apt-get install lvmtools" I
believe.....I would double check that but I am not *gasp* in Linux right now

vgcfgrestore only works on a new PV.
Run "pvcreate -ff /dev/YourDevice" *before trying vgcfgrestore on it.
