6 Clurgmgrd - Resource Group (Cluster Service) Manager Daemon
7
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.
14
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.
