Running a shell script on becoming the CARP master?
Greetings, Are there any hooks into CARP to run a shell script when a machine becomes the master? Also, is there a way to force a machine to become the master without powering off the current master (for example to do maintenance on the current master)?

I believe there was supposed to be a utility for this sort of thing but I haven't seen or heard anything about it. In the mean time a program which read the data could probably be built from the ifconfig code quite simply. It would be really nice if there were kevent notifications for CARP events.

From: Matthew Hagerty [EMAIL PROTECTED] Are there any hooks into CARP to run a shell script when a machine becomes the master? Also, is there a way to force a machine to become the master without powering off the current master (for example to do maintenance on the current master)? I don't know of any way to do the former, but for the latter it's easy enough to temporarily adjust the advbase setting higher on the master until failover occurs. Set it to at least three times the setting on the slave. Or simply ifconfig down the carp interface on the master.

David Taking the master carp interface down certainly would accomplish the task, I just didn't know if there was a more elegant method. Thanks for the info.

Do you know if the CARP interface is up, available, and stable by the time /usr/local/etc/rc.d scripts are run?
