Release Notes

Policy changes

  • The optional resource flag is now used to dispatch resources into the "avail" and "optional" lists, instead of using hardcoded driver groups. Service designers can thus choose what resources contribute to the availabilty state, letting other, optional, resources contribute to the overall status. Note the asynchronous, target-state driven, daemon actions only consider the service instances availstatus. For example, a "start" action tells the daemon to take actions for the service to reach the "up availability state", so a service with optional resources down is already considered on-target and no action will be taken.
  • Resources tagged "noaction" are now automatically set optional. Beware, an encap service should have at least one non-optional resource for an availstatus to be evaluated.
  • The disk.scsireserv resources now inherit their peer resource optional and monitor values.

New Features

  • The agent now runs a daemon implementing heartbeats, quorum, scheduling, a remote OpenSVC actions listener and node/services/resources orchestration.
  • The agent now announce its "compat version" in the heartbeats, so as ensure proper communication with other cluster nodes. A lack of "compat version" alignment temporarily disable automated orchestration, until issue is fixed.
  • Add monitor states to svcmgr print status human-friendly and JSON outputs.
  • The frozen service instance status is not longer honored by the CRM, only by the orchestrator.
  • The node is freezeable. A thawed service instance on a frozen node is not orchestrated.
  • Service are created in frozen state by svcmgr create.
  • svcmon output is now cluster-wide and displays daemon information
  • Most commands have adopted a "forest" representation for their human-friendly output: om node pushasset, om node checks, om node pushdisks, svcmgr print schedule, om node print schedule, ...
  • Support JSON output in om node pushdisks, om node checks, om node pushasset.
  • om node unset --param <section>
  • svcmgr enable and svcmgr disable no longer reorder the service configuration file.
  • Near-synchronous service configuration file swapping amongst cluster nodes.
  • Cluster-wide service logs, and follow mode
  • Pervasive support for converters in keyword values and command line argument values: period (ex: 1h10s), size (10mib), speed (10mib/s), shlex, integer, boolean, list, set.
  • Add a size formatter and use it in most command outputs.
  • Use a denser streamlog format.
  • svcmgr -s now accepts service selection expressions
  • Cap the parallel running subprocesses on svcmgr --parallel commands. node.max_parallel node configuration keyword can be used to change the default value (10).
  • The provision local action now leaves the instance in standby state, instead of started.
  • Support different command for stop, start, check, info actions in a app resource.
  • The <svcname>.stonith and <svcname>.cluster symlinks are no longer necessary, and automatically deleted.
  • The DEFAULT.env parameter is now only used to check for service placement : a PRD node can only run PRD/PPRD services
  • Inter-services start dependencies, intra-cluster, using the DEFAULT.parents keyword.
  • Inter-services stop dependencies, intra-cluster, using the DEFAULT.children keyword.
  • Scaler services
  • PowerDNS remote backend


om node thaw, om node freeze, svcmgr start, svcmgr stop, svcmgr freeze, svcmgr thaw, svcmgr provision and svcmgr unprovision commands operate cluster wide. svcmgr unprovision would thus delete all services and their data on all cluster nodes.
