.SH NAME

|
cmirrord \(em cluster mirror log daemon
|
|
|
|
.SH SYNOPSIS
|
|
.B cmirrord
|
|
|
|
.SH DESCRIPTION
|
|
cmirrord 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
|
|
Cluster MANager (CMAN), which must be set up and running in order for
|
|
cmirrord to function. (The cluster infrastructure is also required for
|
|
clvmd.)
|
|
|
|
Output is logged via syslog. The USR1 signal can be issued to cmirrord
|
|
to gather current status information for debugging purposes.
|
|
|
|
Once started, cmirrord will run until it is shutdown via INT 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.
