Strange results after partition-full condition...

[Garance A Drosihn]

I have a test 4.x-stable system that I recently rebooted into.
The last time I had updated it was May 3rd.  I cvsup'ed it,
did the buildworld/installworlds, and everything seemed fine.

I then thought I would update all the ports.  When upgrading
XFree86, the /usr partition ran out of disk space.  Now the
partition shows up as:

(21) df -k
Filesystem  1K-blocks    Used   Avail Capacity  Mounted on
/dev/ad0s2a    251950   35550  196244    15%    /
/dev/ad0s2f    241870      10  222512     0%    /tmp
/dev/ad0s2g   2064302 -164180 2063338    -9%    /usr
/dev/ad0s2e    257998   61258  176102    26%    /var
/dev/ad0s2h   1311026  676644  529500    56%    /Users

This has persisted through a bunch of 'sync's and a system
reboot.  Actually it had started as -1% capacity, but went
to -9% as I removed files (like all of /usr/obj/usr/src ).

I have some other process running right now, but when that is
done I'm going to shutdown and then run fsck on that partition.
I assume that will clear it up.

This is on a dual-CPU system, if that is significant.  The
partition is mounted:
     /dev/ad0s2g on /usr (ufs, local, soft-updates)

This is only a test system, so it isn't much of a problem for
me.  I just thought that it was odd enough that I should
mention it.  Has anyone else seen behavior like this?
