I was just looking at my news server, and it was seriously low on swap
for some obscure reason. (Probably because I only have 130MB on
wd0b.) So I created a 500MB file (/scratch/swapfile) and added it to
the fstab. Then I issued a "swapctl -A".
It said something very similar to:
"Adding nnn bytes of swap on /dev/sd0b."
for me, this returns "Device busy", as it should...
"Adding nnn bytes of swap on /scratch/swapfile."
Hmm. I expected the second line, but not the first. So, being a
suspicious person, I ran "pstat -sk":
/dev/wd0b 131512 112884 18628
/dev/(null) 512000 1088 510912
/dev/wd0b 131512 1476 130036
TOTAL 775025 115448 659577
Umm. At this point, I halted the machine and rebooted, because I
didn't want my pages of virtual memory to stomp all over each other.
So, does anybody know if this was truly a cause for alarm? If so, how
should I go about fixing it? I don't really want to see that happen
again, you see. :)
i've tested this out on 1.3.3 and various -current machines, and i
can not reproduce it. can you do it again?
