5 | .SH SYNOPSIS |
6 | .B cmirrord | |
13acd33b JEB |
7 | |
8 | .SH DESCRIPTION | |
9 | cmirrord is the daemon that tracks mirror log information in a cluster. | |
794b3b16 JEB |
10 | It is specific to device-mapper based mirrors (and by extension, LVM |
11 | cluster mirrors). Cluster mirrors are not possible without this daemon | |
12 | running. | |
13 | ||
14 | This daemon relies on the cluster infrastructure provided by the | |
15 | Cluster MANager (CMAN), which must be set up and running in order for | |
16 | cmirrord to function. (The cluster infrastructure is also required for | |
17 | clvmd.) | |
18 | ||
19 | Output is logged via syslog. The USR1 signal can be issued to cmirrord | |
20 | to gather current status information for debugging purposes. | |
21 | ||
22 | Once started, cmirrord will run until it is shutdown via INT signal. If | |
23 | there are still active cluster mirrors, however, the signal will be | |
24 | ignored. Active cluster mirrors should be shutdown before stopping the | |
25 | cluster mirror log daemon. | |
