There was a bug involving master/slave monitoring not being resumed that got fixed recently. I'd recommend updating to 1.1.8. Here is the related bug report. http://bugs.clusterlabs.org/show_bug.cgi?id=5072 -- Vossel > -------- Пересылаемое сообщение -------- > От кого: Юлия Школьникова <shkolnikova_y...@mail.ru> > Кому: pacemaker@oss.clusterlabs.org > Дата: Mon 19 Nov 2012 16:37:21 > Тема: [Pacemaker] Problem with monitor > > > > > > > Hello, > > I configure master/slave cluster for postgresql 9.1 based on corosync > и pacemaker. > I do it using this presentation: > http://schedule2012.rmll.info/IMG/pdf/postgresql-9-0-ha.pdf . > Resource agent (pgsql-ms) for master/slave postgresql I took from > this: https://github.com/roidelapluie/puppet-cluster . > My nodes are node1 и node2. > > My config file of pacemaker: > > node node1 > node node2 > primitive DBIP ocf:heartbeat:IPaddr2 \ > params nic="eth0" ip="10.76.112.183" cidr_netmask="22" \ > op monitor interval="30s" \ > meta target-role="Started" is-managed="true" > primitive pgsql ocf:inuits:pgsql-ms \ > op monitor interval="5s" role="Master" \ > op monitor interval="10s" role="Slave" > primitive ping ocf:pacemaker:ping \ > params host_list="10.76.112.1" \ > op monitor interval="10s" timeout="10s" \ > op start interval="0" timeout="45s" > group PSQL DBIP > ms pgsql-ms pgsql \ > params pgsqlconfig="/var/lib/pgsql/9.1/data/postgresql.conf" > lsb_script="/etc/init.d/postgresql-9.1" > pgsqlrecovery="/var/lib/pgsql/9.1/data/recovery.conf" \ > meta clone-max="2" clone-node-max="1" master-max="1" > master-node-max="1" notify="true" > clone clone-ping ping \ > meta globally-unique="false" > location connected PSQL \ > rule $id="connected-rule" -inf: not_defined pingd or pingd lte 0 > colocation ip_psql inf: PSQL pgsql-ms:Master > property $id="cib-bootstrap-options" \ > dc-version="1.1.7-6.el6-148fccfd5985c5590cc601123c6c16e966b85d14" \ > cluster-infrastructure="openais" \ > expected-quorum-votes="2" \ > stonith-enabled="false" \ > no-quorum-policy="ignore" \ > default-resource-stickiness="INFINITY" \ > last-lrm-refresh="1352470332" > rsc_defaults $id="rsc_defaults-options" \ > migration-threshold="INFINITY" \ > failure-timeout="10" \ > resource-stickiness="INFINITY" > > > Then I try to test my cluster: > 1) If I switch off the master, then the slave becomes a new master as > expected.
