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.
