Some useful commands to help you if you need to debug a possible problem with HA or clusterXL services.
# cphaprob stat
This command shows you the current status of your ha configuration – ideally you will see OK’s rather than problem, it will also tell you the which node is the primary.
# cphaprob -ia list
This give you a bit more detail on any problems and which if any daemons have failed. So for example, if your fwd daemon has failed you would see a state of problem.
# cphaprob -a if
This shows you the interfaces, whether they are up, and whether they are running multicast or broadcast – this should be the same on the secondary node.
Shows you the host and the currently installed policy along with a list of your interfaces in use.
# netstat -i
Regular linux command, but useful as it shows you the state of your interfaces, and whether there is a possible network problem.
