dlm_controld - dlm cluster control daemon

Description

       The  kernel  dlm  requires  a user daemon to manage lockspace membership.  dlm_controld manages lockspace
       membership using corosync cpg groups, and translates membership changes into dlm kernel recovery  events.
       dlm_controld also manages posix locks for cluster file systems using the dlm.

Name

       dlm_controld - dlm cluster control daemon
