.TH CMIRRORD 8 "LVM TOOLS #VERSION#" "Red Hat Inc" \" -*- nroff -*-

.SH NAME
|
|
cmirrord \(em cluster mirror log daemon
|
|
|
|
.SH SYNOPSIS
|
|
\fBcmirrord\fR [\fB-f\fR] [\fB-h\fR]
|
|
|
|
.SH DESCRIPTION
|
|
\fBcmirrord\fP is the daemon that tracks mirror log information in a cluster.
|
|
It is specific to device-mapper based mirrors (and by extension, LVM
|
|
cluster mirrors). Cluster mirrors are not possible without this daemon
|
|
running.
|
|
|
|
This daemon relies on the cluster infrastructure provided by the corosync,
|
|
which must be set up and running in order for cmirrord to function.
|
|
|
|
Output is logged via \fBsyslog\fP(3). The \fBSIGUSR1 signal\fP(7) can be
|
|
issued to \fBcmirrord\fP to gather current status information for debugging
|
|
purposes.
|
|
|
|
Once started, \fBcmirrord\fP will run until it is shutdown via \fBSIGINT\fP
|
|
signal. If there are still active cluster mirrors, however, the signal will be
|
|
ignored. Active cluster mirrors should be shutdown before stopping the cluster
|
|
mirror log daemon.
