What steps will reproduce the problem?
As can be seen here
(https://groups.google.com/forum/#!topic/ganeti/rWgEUfwYOe8) I accidentally
used DRBD 8.4. After that I downgraded to the DRBD 8.3.11 (as you can see
above), but I am still getting the "There are some degraded disks for this
instance." while creating instances or doing a burnin. After that I've
reset everything, recreated the LVM vg group and reinitialized the cluster.
I still get the error.
dmesg gives me the following (while instance creation):
