.SH NAME
corosync \- The Corosync Cluster Engine.
.SH SYNOPSIS
.B "corosync [\-f] [\-P num] [\-p] [\-r] [-R] [\-t] [\-v]"
.SH DESCRIPTION
.B corosync
Corosync provides clustering infrastructure such as membership, messaging and quorum.
.SH OPTIONS
.TP
.B -f
Start application in foreground.
.TP
.B -p
Do not set realtime scheduling.
.TP
.B -P
Set priority of process. Has effect only when
.B -r
is not used. Can be ether numeric value with similar meaning as
.BR nice (1)
or
.B max
/
.B min
meaning maximal / minimal priority (so minimal / maximal nice value).
.TP
.B -r
Set round robin realtime scheduling with maximal priority (default). When setting
of scheduler fails, fallback to set maximal priority.
.TP
.B -R
Do not try to move Corosync to root cpu cgroup. This feature is available only
for cgroups with RT sched enabled systems (Linux with
CONFIG_RT_GROUP_SCHED kernel option). It's also expected to be removed as soon as
systemd gets support for managing RT configuration.
.TP
.B -t
Test configuration and then exit.
.TP
.B -v
Display version and SVN revision of Corosync and exit.
