I'm running OpenBSD 4.2/amd64 on an Opteron machine.
I boot off of wd0, which is a flash disk.
I also have sd0, which I use for more frequently writable partitons (swap,
var, tmp, etc) (sdo is really a set of raid disks managed by an areca disk
controller)
Here is my /etc/fstab:
# more /etc/fstab
/dev/wd0a / ffs rw 1 1
/dev/wd0g /home ffs rw,nodev,nosuid 1 2
/dev/sd0f /home2 ffs rw,nodev,nosuid 1 2
/dev/sd0d /tmp ffs rw,nodev,nosuid 1 2
/dev/wd0e /usr ffs rw,nodev 1 2
/dev/sd0e /var ffs rw,nodev,nosuid 1 2
/dev/sd0b none swap sw 0 0
Note wd0b is not specified, and sd0b is.
When I boot the machine, I see:
root on wd0a swap on wd0b dump on wd0b
I guess the kernel devaults to wd0b for swap and dump?
Anyway, the next log line is:
swapctl: adding /dev/sd0b as swap device at priority 0
So that seems good, it is picking up the real swap space out of /etc/fstab
(after the machine boots, I run:
# swapctl -l
Device 512-blocks Used Avail Capacity Priority
/dev/sd0b 8401932 0 8401932 0% 0
so that seems consistent that the kernel is using sd0b for swap)
But later in the boot messages I see:
savecore: /dev/wd0b: Device not configured
Presumably this is because
rc.conf has:
savecore_flags= # "-z" to compress
and /etc/rc has:
if [ -d /var/crash ]; then
savecore ${savecore_flags} /var/crash
fi
So, how can fix it so savecore executes successfully in the rc script?
After the machine booted, I tried running
# savecore /dev/sd0b
savecore: /dev/wd0b: Device not configured
thinking that if I just specified the actual swap partition it would work,
but clearly it didn't.
How can I configure savecore to use the real swap partition on this system?
