Can I add or remove a node from cluster by just adding/removing it

cluster.conf? Is that kind of cluster reconfiguration supported

Provided your cluster has more than 2 nodes, this should work fine. (I
believe two node clusters are special.)
Make sure you bump the version number of cluster.conf after any change.
We also run "ccs_tool update" afterwards to propagate the new config to
other nodes before starting cman on the new node. If removing a node,
we stop it before removing from the config file.
Yes, you must stop a node before removing it from cluster.conf. Also be
aware that removing a node from cluster.conf will not remove it from the
"cman_tool" display unless you are running cluster3.
