Hi Howard, It's a matter of preference. You summed up the pros and cons of each side quite well. :) The manual approach leans more to safety. For example, if a node got fenced because its network card is flaky, or a disk is having write errors, then having it automatically rejoin is just going to repeat the problem. The automated approach leans more to quick self-recovery, and is more convenient in larger organizations where not every administrator that has access to the host for applying updates etc. is trained on the cluster software. -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
