NAME

       dlm_controld - dlm cluster control daemon

SYNOPSIS

       dlm_controld [OPTIONS]

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.

       For default settings, see dlm_controld -h.
