Having trouble getting system dump after a (repeatable) crash.
10.3-RELEASE-p20 FreeBSD 10.3-RELEASE-p20 #0: Wed Jul 12 03:13:07
UTC 2017 root@amd64-builder.daemonology.net:/usr/obj/usr
/src/sys/GENERIC amd64
I originally had crash dumps disabled, so changed
dumpdev="NO" to "AUTO" in rc.conf
but still no dump in /var/crash after a crash and reboot.
only thing in /var/crash is minfree, which says "2048"
On boot I see the message "No suitable dump device was found"
which I presume is the problem.
An issue may be my sys config, as /tmp and swap are memdisks.
Not sure how or if I can modify fstab or the config to get swap
on disk for a crash dump save since the disk has no swap or tmp
partitions.
From fstab:
/dev/ufs/hd250G1root / ufs rw,noatime 1 1
/dev/ufs/hd250G1var /var ufs rw,noatime 2 2
/dev/ufs/hd250G1usr /usr ufs rw,noatime 7 3
tmpfs /tmp tmpfs rw,mode=01777 0 0
md99 none swap sw,file=/usr/swap/swap,late 0
