Gents, I'm trying to configure a HA cluster with RHEL 6.5. Everything goes well except the fencing. The cluster's node are not connected to the management lan (where stand all the iLO/UPS/APC devices) and it's not planned to connecting them to this lan.
With these constraints, I figured out that a way to get fencing working is to use *fence_sanlock*. I followed this tutorial: https://alteeve.ca/w/Watchdog_Recovery and I it worked (I got some problem with SELinux that I finally disabled like specified in the following RHEL 6.5 release note: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.5_Technical_Notes/ ) So perfect. The problem is that fence_sanlock relies on cman and not pacemaker. So with stonith disabled, pacemaker restarts the resources without waiting for the victim to be fenced and with stonith enabled, pacemaker complains about the lack of stonith resources and block all the cluster. I tried to put fence_sanlock as a stonith resource at the pacemaker level but as explained there http://oss.clusterlabs.org/pipermail/pacemaker/2013-May/017980.html it does not work and as explained there https://bugzilla.redhat.com/show_bug.cgi?id=962088 it's not planned to make it work. My question: is there a workaround ?
