I've reported similar behaviour before. I'm running /tmp on mfs. Here's what I have: $ df /tmp Filesystem 1048576-blocks Used Avail Capacity Mounted on mfs:272 30 0 28 0% /tmp $ pstat -s Device 1048576-blocks Used Avail Capacity Type /dev/wd0s1b 49 45 4 91% Interleaved /dev/sd0b 399 72 326 18% Interleaved Total 449 118 331 26% Note that all the values are in MB. I mount /tmp from /etc/rc.local, and specify /dev/sd0b as the swap partition, so it *should* give me 449 MB. Instead it gives me 30, with no explanation. If I umount it and mount it again, I get the full 449 MB (or I did last time I tried; that means stopping X, and I don't want to do that). I haven't been complaining about this, because I know that people will, with justification, ask me what I'm doing to fix it. But I'm sure it's a bug.
