NAME

6       Clurgmgrd - Resource Group (Cluster Service) Manager Daemon
7

DESCRIPTION

9       Clurgmgrd  handles  management  of  user-defined cluster services (also
10       known as resource groups).  This includes  handling  of  user  requests
11       including service start, service disable, service relocate, and service
12       restart.  The service manager daemon also handles restarting and  relo‐
13       cating services in the event of failures.

HOW IT WORKS

16       The  service manager is spawned by an init script after the cluster in‐
17       frastructure has been started and ccsd has been spawned, and only func‐
18       tions when the cluster is quorate.
19
20       During  initialization,  the  service manager runs scripts which ensure
21       that all services are clear to be started.  After that,  it  determines
22       which services need to be started and starts them.
23
24       When  an  event  is  received,  members which are no longer online have
25       their services taken away from them.  The event should  only  occur  in
26       the case that the member has been fenced whenever fencing is available.
27
28       When  a  cluster  member determines that it is no longer in the cluster
29       quorum, the service manager stops all services and waits for a new quo‐
30       rum to form.
