[Pacemaker] Two slave nodes, neither will promote to Master

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" \
        op monitor on-fail="restart" interval="5s"
primitive clusterIParp ocf:heartbeat:SendArp \
        params ip="10.64.96.31" nic="eth1:1"
primitive fs_nfs ocf:heartbeat:Filesystem \
        params device="/dev/vg_shared/lv_nfs_01" directory="/shared"

        op start interval="0" timeout="240" \
        op stop interval="0" timeout="240" on-fail="restart"

These are the installed packages

If anyone has any idea/suggestion/input/etc. I'd be grateful.
