The question is once the node comes back it should remove the constraint automagically, why doesn't it do it here as well?
Maybe it's missing the crm-unfence-peer.sh in the same /etc/drbd.conf file? >> location cli-prefer-g_clust04 g_clust04 \ >> rule $id="cli-prefer-rule-g_clust04" inf: #uname eq >> ha07a.mydomain.com >> location cli-prefer-g_clust05 g_clust05 \ >> rule $id="cli-prefer-rule-g_clust05" inf: #uname eq >> ha07b.mydomain.com >> > > I've went through something similar, and this could be the case as well, the combined score for the group is higher than the resource-stickiness value, setting it to a much higher value (or even inf:) would do the job.
