How can I configure my RHEL High Availability cluster with pacemaker to monitor the link status of a network interface and relocate resources if a failure occurs?
Issue
- I am running an
IPaddr2
resource in my cluster, but it doesn't react when the link goes down. How can I tellpacemaker
to monitor the link and run this resource on a node that has an active link? - I'm using the
ethmonitor
resource agent and it logs monitor failures when the link goes down, but the resource doesn't fail or move to another location. - How can I configure my cluster to monitor a network link and move resources somewhere else if the link fails?
Environment
- Red Hat Enterprise Linux (RHEL) 6, 7, 8 and 9 with the High Availability Add On
pacemaker
- One or more network interfaces that need to be monitored for health
