NAME

6       dlm_controld - dlm cluster control daemon

SYNOPSIS

10       dlm_controld [OPTIONS]
11
12

DESCRIPTION

14       The  kernel  dlm requires a user daemon to manage lockspace membership.
15       dlm_controld manages lockspace membership using  corosync  cpg  groups,
16       and  translates  membership  changes  into  dlm kernel recovery events.
17       dlm_controld also manages posix locks for cluster  file  systems  using
18       the dlm.
