I make next resource agent - https://github.com/rnz/resource-agents/blob/master/heartbeat/couchdb At end of file exist next example configuration: ------------ node vub001 node vub002 primitive couchdb-1 ocf:heartbeat:couchdb \ params dbuser="user" dbpass="pass" replcmds=" http://admin:pass@192.168.1.2:5984/testdb,http://admin:pass@127.0.0.1:5984/testdb,true;http://admin:pass@192.168.1.2:5984/testdb1,http://admin:pass@127.0.0.1:5984/testdb1,true;"; \ op start interval="0" timeout="20s" \ op stop interval="0" timeout="20s" \ op monitor interval="10s" \ meta target-role="Started" primitive couchdb-2 ocf:heartbeat:couchdb \ params dbuser="user" dbpass="pass" replcmds=" http://admin:pass@192.168.1.1:5984/testdb,http://admin:pass@127.0.0.1:5984/testdb,true;http://admin:pass@192.168.1.1:5984/testdb1,http://admin:pass@127.0.0.1:5984/testdb1,true;"; \ op start interval="0" timeout="20s" \ op stop interval="0" timeout="20s" \ op monitor interval="10s" \ meta target-role="Started" primitive vIP ocf:heartbeat:IPaddr2 \ params ip="192.168.1.10" nic="eth1" \ op start interval="0" timeout="20s" \ op stop interval="0" timeout="20s" \ op monitor interval="5s" timeout="20s" depth="0" \ meta target-role="Started" location cdb-1-c couchdb-1 inf: vub001 location cdb-1-p couchdb-1 -inf: vub002 location cdb-2-c couchdb-2 inf: vub002 location cdb-2-p couchdb-2 -inf: vub001 location vIP_c vIP 100: vub001 location vIP_p vIP 10: vub002 property $id="cib-bootstrap-options" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ no-quorum-policy="ignore" \ stonith-enabled="false" \ symmetric-cluster="false" \ rsc_defaults $id="rsc-options" \ resource-stickiness="110" ---------- One CouchDB resources infinite stay per node, because use master-master/multi-master replication. And I want to make easy couchdb replication, without use external files for configuration of replication.
Need resource vIP migrate to next node by check fail/stop state resource couchdb (per node). How make it in pacemaker configuration? May be use "location rule: #uname " or need additional RA for control state (as pingd)? May use next method: #!/bin/bash curl -s http://127.0.0.1:5984 | grep -q 'couchdb' if [ $? != 0 ]; then #... add control by crm_mon of started couchdb on current node crm resource migrate vIP crm configure delete cli-standby-vIP fi But I think, this is not good.... P.S. Sorry for my bad English...
