This BZ is to track the updates to the SBD fencing article on the customer portal, as per this exchange: From Ken Gaillot: To summarize the support issue, this is where I think we should be: * SBD is supported on RHEL 6.8 and later, and 7.1 and later. * On RHEL 6, using SBD in clusters with an even number of nodes is not supported, due to the lack of auto_tie_breaker. * On RHEL 7, using SBD in clusters with an even number of nodes is supported if "auto_tie_breaker: 1" is set in /etc/corosync/corosync.conf. (Also, the article should mention doing this step.) * The other limitations in the article still apply: no Pacemaker Remote (likely coming in 7.4, maybe 7.3.z if there is demand), no poison pill (hopefully also 7.4), no software watchdogs (never). Plus this, included here for completeness: >>> https://access.redhat.com/solutions/2172091 >>> >>> is the other reference we have for sbd support policies, which repeats >>> the 'not supported in 6' line. So obviously we missed something if that >>> has changed. The above should be updated; the equivalent notice for 6.8+ is: https://access.redhat.com/errata/RHEA-2016:0985
To simplify finding it in the above exchange, this is the article to update: https://access.redhat.com/articles/2212861
