Re: Cannot obtain kernel dump in /var/crash

Hello,

funny questions for me as I'm not a newbie in FreeBSD... ;) But
I'll answer.

Do you have a swap device defined, particularly in /etc/fstab?o
What does swapinfo say?
/home/minotaur>swapinfo
Device 1K-blocks Used Avail Capacity
/dev/ad2s1b 1048576 0 1048576 0%

Does the same happen if you say dumpdev="auto" or if you remove
the -f flag from savecore_flags?
The same behavior.

It may be worth peeking through /etc/rc.d/dumpon and imitating
some of the commands there to see if you can reproduce it.

/etc/rc.d/dumpon creates symbolic link /dev/dumpdev. It's present in
my /dev directory. I think a problem is somewhere deeply, probably
with savecore(8). When a panic occurs I see in console process of
dumping (size of RAM, number of pages, dump device etc.) and it's
completely normal.
