I was aware of the 'copy, update and merge' approach but didn't think the behaviour would be any different to editing live. No matter, just so long as I know :) gdh ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems

I didn't realise it was supposed to work. Can't edit any groups without deleting them first, which also deletes all constraints. It's a pain but the CRM shell is so great otherwise I've just accepted it.

[Linux-HA] Adding to a group without downtime
Hi :) I'm using the Lenny packages http://people.debian.org/~madkiss/ha/ and have been enjoying success with pacemaker + heartbeat (I've used a heartbeat v1 config for years without problems). I have a few IPaddr2 primitives in groups, but I'd like to understand how I can add a new primitive into an existing group without stopping/starting. At the moment I have to: # primitive failover-ip-186 ocf:heartbeat:IPaddr2 params ip="10.8.2.186" op monitor interval="10s" # show www-frontends group www-frontends failover-ip-184 failover-ip-185 # delete www-frontends # group www-frontends failover-ip-184 failover-ip-185 failover-ip-186 # commit But that takes failover-ip-184 and failover-ip-185 down for a couple of seconds. Is there a way to add a new primitive to a group with zero downtime? I tried using 'edit www-frontends' to stick failover-ip-186 on the end of the line but it complains loudly "Call cib_modify failed (-47): Update does not conform to the configured schema/DTD" Thanks for such great software! :) Cheers Gavin. ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
