Are you wanting to move all the resources back or just that one resource? I'm still learning, but one simple way I move all resources back from nodeb to nodea is like this:
# on nodeb sudo crm node standby # now services migrate to nodea # still on nodeb sudo crm node online This may be a naive way to do it but it works for now :) There is also a "crm resource migrate" to migrate individual resources. For that, see here: http://www.clusterlabs.org/doc/crm_cli.html ----- Original Message ----- > From: "Dominic Malolepszy" <dmalolep...@optusnet.com.au> > To: pacemaker@oss.clusterlabs.org > Sent: Thursday, March 3, 2011 12:18:51 AM > Subject: [Pacemaker] Failing back a multi-state resource eg.
