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
