Hi,I'd like to find out where to put the "upsdrvctl shutdown" in the shutdown process. Putting it in rc.shutdown causes me to have dirty filesystems constantly that sometimes don't allow the system to come up.
I seem to recall someone saying that the best way to do this was to create some flag-file, and then reboot instead of shutdown. Then very early in the system-startup you look for that flag-file, and run 'upsdrvctl shutdown'. Since you just successfully went through the complete shutdown, all the disks should be in a safe state. So, the UPS will yank the power out from under the computer, but it won't matter. The trick, of course, is to add some logic there so you can boot up after the power has returned! Either check the last-change date of the flag-file, or maybe do something to re-mount '/' as writable, delete the one file, and re-mount it back as read-only. I have never done any of this with my own UPS, so I'm not sure of the details... :-) -- Garance Alistair Drosehn = [EMAIL PROTECTED] Senior Systems Programmer or [EMAIL PROTECTED] Rensselaer Polytechnic Institute or [EMAIL PROTECTED] _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
