Continentalclusters Version A.06.01 Release Notes Known Problems and Workarounds Persistent “cmomd” Processes • What is the problem? If the node where the monitor process (cmclsentryd) is running goes down and then comes back up (as in a power failure), the cmomd process will remain on one or more nodes in the cluster that is being monitored. In these circumstances, the cmomd process will continue on the system until terminated by a user.
Continentalclusters Version A.06.01 Release Notes Known Problems and Workarounds The default behavior of LVM is to retry access forever following a failure. There are a number of ways to recover from this application hang problem: — Reboot the node. The package will then move to another node in the cluster. — Fix the problem so that one or more PV Links is restored. The application will then continue normally. — It is also possible to change the default LVM behavior so that it will not retry forever.
