Hi,
I'm currently looking at two VMs which are supposed to mount a drive in
a given directory, depending on who's the master. This was decided above
me, therefore no DRBD stuff (which would've made things easier), but
still using corosync/pacemaker to do the cluster work.
As it is currently, both nodes are online and configured, but none are
switching to Master. In lack of a DRBD resource, I tried using the Dummy
Pacemaker. If that's not the correct RA, please enlighten me on this too.
Below's the current config:
node NODE01 \
attributes standby="off"
node NODE02 \
attributes standby="off"
primitive clusterIP ocf:heartbeat:IPaddr2 \
params ip="10.64.96.31" nic="eth1:1" \
