dlm_controld — dlm cluster control daemon


dlm_controld [Options]


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.


Command line options override a corresponding setting in dlm.conf(5).
For default settings, see dlm_controld -h.
