                Dear Experts,

                We are facing a strange problem. We have a File Domain named
"oracle" under ver5.1, with the File Sets "u111", "u112", "u113" (no
file-set quotas assigned). These are mounted on directories under "/" with
the same names (i.e. on "/u111", "/u112", "/u113"). The output of df -k
shows:
        
----------------------------------------------------------------------------

---
		Filesystem        1024-blocks        Used      Available
Capacity  Mounted on
		oracle#u111          16013104    15948056             0
100%         /u111
		oracle#u112          16013104                16
0   100%         /u112
		oracle#u113          16013104          13048             0
100%         /u113
	
----------------------------------------------------------------------------
---
		As per the above, the file system "/u111" is full.
		However, I ran the "du -s" command on each of the mounted
directories and got the following output 
		(bytes=output*512):-
		COMMAND	  OUTPUT		   CALCULATED AS
		"du -s /u111" -   16059728		[i.e. 8,222,580,736
bytes]
		"du -s /u112" -               64		[i.e.
32,768 bytes]
		"du -s /u113" -         26144		[i.e.
13,385,728 bytes]
		Hence, as per the "du" command only 8,235,999,232 bytes are
used. Though I understand there may be a slight variation between bytes
shown by "du -s" and "df -k", the above case shows a whole 8GB missing!!!
		Any comments on why this could be happening please? Would
sincerely appreciate your assessment. Thanks.
