Correct? if you don't want reboot your machine after changing rc.conf you can run `/etc/rc.d/dumpon start`. It will mark your swap as a dumpdev. At the boot time /etc/rc.d/dumpon will be started automatically (if "dumpdev" is set). After system crash the kernel memory dump will be saved to the dempdev and after reboot dump will be extracted from the swap into dumpdir by the savecore. Yes, That occurred to me immediately after replying to you - dumpdev="AUTO" already ensures that. :) Thanks again for all your time and trouble. --Chris -- WBR, Andrey V.

dumpdev question (probably stupid)
Greetings, Given that the server that I need to create a dumpdev on has has a slice dedicated to /var with *more* than adequate space to accommodate the the resources needed for a dumpdev, as well as everything else in /var. Is it enough to simply: # mkdir /var/crash # chmod 700 /var/crash and set *dumpdev* in */etc/fstab* as such?: # Device MountpointFStype OptionsDump Pass# /dev/ad0s1b none swap sw 0 0 /dev/ad0s1a / ufs rw 1 1 /dev/ad0s1d /var ufs rw 2 2 # dumpdev /dev/ad0s1d /var/crashufs sw 0 0 #cdrom /dev/acd0 /cdromcd9660 ro,noauto 0 0 then bounce the system and *assume* I have a /suitable/ and /useable/ dumpdev available? Sorry if I have made any ridiculous assumptions, and thank you for your time. --Chris -- panic: kernel trap (ignored) ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
