For the most part, these seem to be caused by someone issueing a cmrunnode to start a cluster verses the cmruncl. Doing this causes the node to look for a cluster that doesn’t exist. Apparently, the cmcld daemon doesn’t quite have the smarts to realize that something’s amiss, so it waits… and waits…
There’s a few things you can try to get around this mess.
cmhaltcl -f
. This probably won’t work, but it’s worth a try.Enter
cmrunnode
on another node to see if the two can link up.Reboot the affected node.
kill cmcld as a last resort
