So yesterday I ran yum update that puled in the new pacemaker and tried
to restart it. The node went into its usual "can't unmount drbd because
kernel is using it" and got stonith'ed in the middle of yum transaction.
The end result: DRBD reports split brain, HA daemons don't start on
boot, RPM database is FUBAR. I've had enough. I'm rebuilding this
cluster as centos 6 + heartbeat R1.
Centos 7 + DRBD 8.4 + pacemaker + NFS server: FAIL. You have been warned.
