Folks,

Two days ago I have hit into problem that make failed because of
"disk full" error, but df(1) shown me that about 55% space at work
slice is available. Check of this slice with du(1) shown
that it's 100% utilized. I thought that it could be disk error - after
manual execution of fsck(8) problem was solved, but after my boot
into -CURRENT next time problem re-appeared.

I have dual boot machine with -STABLE and -CURRENT (both have own
boot slices and few slices are shared between them.) Both -CURRENT
and -STABLE from 10 Oct. Kernel configuration is almost GENERIC (except
removing some unneeded stuff.) Few slices have softupdates enabled, few
disabled. Problem affects all of them.

Following scenario is 100% reproducable here.

1. Run fsck in single user mode under -STABLE (Summary informaton fixed)

2. Run df -k (correct one, checked with du(1))

Filesystem  1K-blocks    Used   Avail Capacity  Mounted on
[..]
/dev/ad0s1f  17026542 9821156 5843264    63%    /home
/dev/ad0s1e   4129310  415998 3382968    11%    /usr/local
[..]

3. immdiatelly reboot to -CURRENT

Filesystem  1K-blocks    Used    Avail Capacity  Mounted on
[..]
/dev/ad0s1f  17026542 3749466 11914954    24%    /home
/dev/ad0s1e   4129310  256922  3542044     7%    /usr/local
[..]

4. immediately reboot to -STABLE again

Filesystem  1K-blocks    Used    Avail Capacity  Mounted on
[..]
/dev/ad0s1f  17026542 3749466 11914954    24%    /home
/dev/ad0s1e   4129310  256922  3542044     7%    /usr/local
[..]

Resume: problem appears after boot of -CURRENT and is permanent (even
after reboot back to -STABLE) until fsck(8) executed.

Anyone else seen it ?
