It's a cluster wide option, so enabling it from any is fine. And yes, stop pacemaker/corosync on all nodes (while in maintenance-mode) and then start pacemaker/corosync again on all nodes .... old cluster status is gone ... check your cluster and disable maintenance-mode -- no service interruption expected Regards, Andreas -- Need help with Pacemaker? http://www.hastexo.com/now > > >> >> Message: 3 >> Date: Wed, 11 Apr 2012 00:12:10 +0200 >> From: Andreas Kurz <andr...@hastexo.com> >> To: pacemaker@oss.clusterlabs.org >> Subject: Re: [Pacemaker] DRBD Split-brain (recovered), but still >> showing "Failed Actions" >> Message-ID: <4f84b03a.4030...@hastexo.com> >> Content-Type: text/plain; charset="iso-8859-1" >> >> On 04/10/2012 05:43 PM, Reid, Mike wrote: >>> Thank you for the suggestion, Andreas.
