DLM_CONTROLD(8)			      dlm		       DLM_CONTROLD(8)

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.
