dlm_controld man 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.

Options

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