Hello,
I have a two node cluster running pacemaker/heartbeat and drbd which
is replicating an ext3 disk. Everything works with the following
exception, when the master node "fails" and the slave node is promoted
to master, the disk resource is not mounted automatically on the new
master.
For example:
1) Node alpha is master and /dev/drbd/by-res/r0 is mounted.
2) I stop the heartbeat service on alpha.
3) Alpha becomes a slave and automatically UNmounts /dev/drbd/by-res/r0.
4) Node bravo assumes the master role, but does not automatically
mount /dev/drbd/by-res/r0; I have to do this manually.
Can anyone advise how I get the slave (in this case, "bravo") to
automount the resource after it is promoted to master? See configs
below.
Thanks,
Craig.
