The /home filesystem was full (121G partition on a 3ware escalade raid)
So i deleted 7G, but df did not show any difference. The fs is mounted w/ soft-updates. I issued a sync command, but still no change. The files were no longer shown in ls, but space was not freed.

Was some process holding those files open? The space doesn't get freed until that process terminates.

So i decided to reboot, to make sure that the deleted files are not still opened by some process. The shutdown went normal, but at the
end it said:

syncing disks..

3321 3321 3321 3316 .....

I dont't know the exact numbers anymore, but it printed some 40x80 lines of 4 digit numbers, the last line was all 1s and then said:

When you rebooted, your system had ~3300 buffers of data that had not yet been written to disk. It was able to write almost all of them out to disk, but it failed with one:

giving up on 1 buffers.

When rebooting, all fs were unclean and i had to wait the usual 20 minutes for fsck to complete.

Yes. FreeBSD probably should have marked the other filesystems (except for the one with the open buffer) as clean. But fsck'ing after a moderately serious problem-- even if you may not have really needed to-- is a fail-safe approach.
