.SH DESCRIPTION
cmirrord is the daemon that tracks mirror log information in a cluster.
-Cluster mirrors are not possible without this daemon running.
+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.
