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.
