Pacemaker 2.1.3 - Release Candidate 1

on GitHub

Features added since Pacemaker-2.1.2

• Internal failures of resource actions (such as an OCF agent not being found) are shown with a detailed exit reason in logs, crm_mon output, etc.
• Support for CIB entries with type="ping" is deprecated (this was an undocumented means of defining a quorum-only node)
• build: configure script supports experimental --enable-nls option to enable native language translations (currently only Chinese translations of certain help text are available)
• CIB: resources support allow-unhealthy-nodes meta-attribute to exempt the resource from bans due to node health checks (particularly useful for health monitoring resources themselves)
• CIB: multiple-active cluster property can be set to "stop_unexpected" to leave the expected instance running and stop only any unexpected ones
• CIB: bundles support resource utilization
• pacemakerd: regularly check that subdaemons are active and accepting IPC connections so sbd can self-fence a node with a malfunctioning subdaemon
• pacemaker-schedulerd: support --output-as/--output-to options including XML output with interactive options
• tools: cibadmin --show-access option to show CIB colorized for ACLs
• tools: crm_attribute supports standard --output-as/--output-to options
• tools: crm_mon output indicates if a node's health is yellow or red
• tools: for probes that failed because the service is not installed or locally configured, crm_mon displays the resource as stopped rather than failed
• tools: crm_rule supports standard --output-as/--output-to options, allows passing multiple -r options, and is no longer experimental
• tools: stonith_admin fencing commands display reasons for failures
• resource agents: HealthSMART supports OCF 1.1 standard and new OCF_RESKEY_dampen and OCF_RESKEY_smartctl parameters

Fixes since Pacemaker-2.1.2

• build: avoid circular library dependency (regression introduced in 2.1.0)
• systemd: if pacemakerd exits immediately after starting, wait 1 second before trying to respawn, and allow 5 attempts
• fencer: get fencing completion time correctly (regression introduced in 2.1.2)
• fencer: avoid memory leak when broadcasting history differences (regression introduced in 2.1.0)
• controller: correctly match "node down" events so remote nodes don't get fenced when connection is stopped (regression introduced in 2.1.2)
• executor: avoid possible double free during notify operation (regression introduced in 2.1.1)
• tools: get stonith_admin -T/--tag option working again (regression introduced in 2.0.3)
• resources: use correct syntax in Stateful meta-data (regression introduced in 2.1.0)
• corosync: repeat corosync_cfg_trackstart if first attempt fails
• executor,scheduler: treat "no secrets" fence results as a hard error
• fencing: handle dynamic target query failures better
• fencing: don't set stonith action to pending if fork fails
• pacemakerd: avoid race condition when subdaemaon is checked while exiting
• scheduler: avoid memory leak when displaying clones in certain conditions
• scheduler: properly set data set flags when scheduling actions
• tools: prevent possible crm_resource crashes if multiple commands specified
