bug in ufs?

[Marat N.Afanasyev]

hello!

i have a strange problem with writing data to my ufs2+su filesystem.

1. i made a 1T gpt partition on my storage server, and formatted it:
newfs -U -m 0 -o time -i 32768 /dev/da1p3a

2. i tried to move data from other servers to this filesystem, total 
size of files is slightly less than 1T

3. i encountered a 'No space left on device' while i still have 11G of 
free space and about 13 million free inodes on the filesystem:

#df -ih
Filesystem     Size    Used   Avail Capacity  iused    ifree %iused 
Mounted on
/dev/da1p3a    1.0T    1.0T     11G    99% 20397465 13363173   60% 
/mnt/45_114

all i want to know is whether this is a bug or a feature? and if such a 
behavior is well-known, where can i read about it?
