NAME¶
dlm_controld - dlm cluster control daemonSYNOPSIS¶
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.OPTIONS¶
Command line options override a corresponding setting in dlm.conf(5).For default settings, see dlm_controld -h.
