When multiple ports/names are configured for a cluster node with `pcmk_host_map` only one of the ports have an action (off, on, reboot) executed.

Solution Unverified - Updated

Environment

  • Red Hat Enterprise Linux Server 7, 8 (with the High Availability Add On)
  • pacemaker

Issue

  • When multiple ports/names are configured for a cluster node with pcmk_host_map only one of the ports have an action (off, on, reboot) executed.

Resolution

Red Hat Enterprise Linux 7
  • There is no plan to fix this issue in RHEL 7.

Red Hat Enterprise Linux 8

Workaround

Create a stonith device for each port (even if connecting to the same stonith device) used by the cluster node as shown in the following solution: [How can I configure fencing for redundant power supplies in a RHEL 6 or 7 High Availability cluster with pacemaker?](https://access.redhat.com/solutions/1173123)

Root Cause

This is a known issue where only 1 of the ports or name values for a cluster node defined in pcmk_host_map has an operation (off, on, reboot) ran against it. This is problem for cluster nodes that have redundant stonith devices defined for a cluster node as not all the stonith devices will be turned off which means the cluster node will not be properly fixed.

Diagnostic Steps

  • Check the pcs cluster cib output to see if there are multiple ports configured for a stonith devices pcmk_host_map attribute. For example it would look similar to the following: pcmk_host_map="node1.example.com:port1,port2;node2.example.com:port3,port4"
