Clurgmgrd - Resource Group (Cluster Service) Manager Daemon
Clurgmgrd handles management of user-defined cluster services (also
known as resource groups). This includes handling of user requests
including service start, service disable, service relocate, and service
restart. The service manager daemon also handles restarting and
relocating services in the event of failures.
HOW IT WORKS
The service manager is spawned by an init script after the cluster
infrastructure has been started and ccsd has been spawned, and only
functions when the cluster is quorate.
During initialization, the service manager runs scripts which ensure
that all services are clear to be started. After that, it determines
which services need to be started and starts them.
When an event is received, members which are no longer online have
their services taken away from them. The event should only occur in
the case that the member has been fenced whenever fencing is available.
When a cluster member determines that it is no longer in the cluster
quorum, the service manager stops all services and waits for a new
quorum to form.
