[ClusterLabs] FYI: regression using 2.0.0 / 1.1.19 Pacemaker Remote node with older cluster nodes

[Ken Gaillot]

Hi all,

The just-released Pacemaker 2.0.0 and 1.1.19 releases have an issue
when a Pacemaker Remote node is upgraded before the cluster nodes.

Pacemaker 2.0.0 contains a fix (also backported to 1.1.19) for the
longstanding issue of "crm_node -n" getting the wrong name when run on
the command line of a Pacemaker Remote node whose node name is
different from its local hostname.

However, the fix can cause resource agents running on a Pacemaker
Remote node to hang when used with a cluster node older than 2.0.0 /
1.1.19.

The only workaround is to upgrade all cluster nodes before upgrading
any Pacemaker Remote nodes (which is the recommended practice anyway).
