Hi there I'm running a Fedora Core 4 High availability cluster with DRBD (RAID over IP) mirroring.
Now i want to create a monitor, that checks the status of the DRBD service. My problem is, that i never wrote a program with perl. There is a command for DRBD status check: drbdadm cstate drbd. The output of this command can be for example: Unconnected, Connected, WFConnection.. For some states, i need an action. For example, When i have the state Unconnected, i want to reconnect DRBD, so that the state is "Connected" again. My question is, what should this monitor script contain, that it can communicate with mon? I think, there should be defined some exit codes and actions according to those exit codes, but i really don't know how to realize this.. I need this informations, that the perl programmer of our company knows, how such a script should work. Any hints to this ? Or is a bash-script based monitor possible, too? How would this work? I hope, you can help me Greets -- 5 GB Mailbox, 50 FreeSMS http://www.gmx.net/de/go/promail +++ GMX - die erste Adresse f�r Mail, Message, More +++ _______________________________________________ mon mailing list mon@linux.kernel.org http://linux.kernel.org/mailman/listinfo/mon
