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. .SH SEE ALSO +.BR lvm (8) .BR clvmd (8) +.BR cluster.conf (5) \ No newline at end of file
