Fixed In Version: pacemaker-1.1.18-11.el7_5.4 Doc Type: Bug Fix
Doc Text:
Cause: When SBD is configured on the cluster nodes, Pacemaker Remote nodes (including guest nodes and bundle nodes) will compare the local SBD configuration and abort if not compatible. Consequence: Guest nodes and bundle nodes unnecessarily fail when SBD is used on the cluster nodes, since they use resource recovery rather than standard fencing mechanisms. Fix: Pacemaker Remote skips the SBD compatibility check when run on a guest node or bundle node. Result: Guest nodes and bundle nodes may be used in a cluster with SBD, without configuring SBD on the guest nodes or bundle nodes themselves.

Fixed in upstream 1.1 branch by commit 4dae674

Comment 3 Ken Gaillot 2018-11-06 21:28:24 UTC
QA: To reproduce, configure a cluster with a guest node and/or bundle, where all the cluster nodes use sbd for fencing. Configure a resource to run on the guest node and/or in the bundle that will require contacting the CIB or controller, such as galera, redis, or rabbitmq (or a modified Dummy resource that calls something like cibadmin -Q). Before the fix, the guest node and/or bundle instance will get restarted when the resource starts on it; after the fix, it will proceed normally.
