Are you using clustered LVM? If not, you probably should be.
You could try deactivating the VG then reactivating it and seeing if the
new primary sees the LV.

Dear all,
I want to build an HA setup with virtual machines on a two hardware
node setup. I already setup a nested LVM DRBD configuration. But from
the second node I can't see the lv's from the drbd device; pvscan
displays it.
Has anybody an idea whats wrong with my setup? I think I need a
primary/primary drbd device because if one hardware node fails I want
to start the KVM container from the other one; therefore I need the
latest data of the KVM container.
Please find some logs below...
Thanks a lot for your help in advance!
Best regards,
Markus
