Each one hosts a single DRBD drive. One server is the master and the other is the slave. Ultimately, I will set up LVM to bring the two together to create a fault tolerant SAN; but I have not gotten that far yet.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Problem: when the master node is turned off the second node remains a slave (it is not promoted).

Oddly enough, this worked fine under 1.0.9 with the exception of the fact that no matter how hard I tried I could not keep the master where it was when the failed node was rebooted (no matter how high I set resource-stickiness, the node that came back up was promoted back to master). So, if anyone can help me solve that problem with 1.0.9, I would be happy to simply downgrade.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>On both versions I used variations of the same configuration, all yielding the same results:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>node san1<o:p></o:p></p><p class=MsoNormal>node san2<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>primitive drbd ocf:linbit:drbd params drbd_resource=r0 op monitor interval=60s<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>ms msdrbd drbd meta master-max= 1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>rsc_defaults resource-stickiness=100<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So, as you can see, I am trying to get DRBD working before I move any further.
