Hi

I am receiving the following error when Pacemaker tries to start the LVM volume/logical groups:

Hi

Same thing happens when I try and start the volume group:

Hi

I had USB drives part of Volume Group and on reboot they changed location, also my DRDB drives UUID changed. Suspect the USB and DRBD drive UUID change caused the VG to not allow it to be started.

Hi

Your question does look a bit confusing to me - since it's not really clear to
me what kind of problem you want to solve.

lvm2 tool is reporting to you that you do have problem with seeing duplicated
devices on your system  (1 PV is visible on multiple different devices -
/dev/drbd0  and  /dev/vg_drbd/lv_drbd   have same signature.

You should probably solve this by setting correct lvm.conf filter - I'd
suggest to set devices you want to 'accept' as PVs  first and reject
everything else (see doc around this setting in lvm.conf file - should be easy
to read and follow).


Then you have there another error reported from DM kernel subsystem - my best
guess is that you already do have a device with same name but different UUID
already active and you get a failure when lvm2 tries to create a same device
with different UUID - but that only my best guess from this short report.

I'd suggest to attach  '-vvvv' trace of failing command and
'dmsetup table'  & 'dmsetup status'  & 'dmsetup info -c'  output listed
if you still have the same problem.

Last but not least - eventually try with clear DM table setting (after reboot).

Regards

Zdenek
