.SH NAME
dlm_controld \- dlm cluster control daemon

.SH SYNOPSIS
.B dlm_controld
[OPTIONS]

.SH 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.
