| .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 |
| Cluster MANager (CMAN), which must be set up and running in order for |
| cmirrord to function. (The cluster infrastructure is also required for |
| \fBclvmd\fP(8).) |
| |
| 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. |
