dlm_controld (8) Linux Manual Page

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.
