[Pacemaker] Concurrent runs of 'crm configure primitive' interfering

2011-09-08 Thread John Spray
Hi, I have some scripts which configure resources across a number of nodes in a cluster. I'm finding that when more than one crm configure primitive invokation is run at the same time, they sometimes interfere with each other: e.g. when adding resource A and B concurrently, I sometimes end up

2011-09-08 Thread Brad Johnson
Thank you for your quick response. First, ideally we do want the best connectivity approach. Assuming each node is connected to the ping hosts via separate NIC's, switches, cables, etc, a failure in one of those components will result in one node having degraded network connectivity. But if
