Re: Probelm in File system
So the correct value is with bdf. The du command reports actual space but can change at any time based on the database activity.

Re: Probelm in File system
Try this to find out open files.
#lsof +aL1 |grep /sapmnt/NWD
or
#lsof +aL1 /sapmnt/NWD
Note down the PID's which is having open files on th filesystem and kill those process.

Re: Probelm in File system
This appears to be an answer to a different question. Sparse files have nothing to do with the bdf vs du conflicts. Sparse files are related to the ll(1) output not adding up to the du or bdf values.

du shows the number of currently allocated blocks.
bdf shows the free disk space available.
The difference is because bdf cannot see the blocks "occupied" by a still active process.
bdf will see the change until the process terminates

You have this reversed. du(1) shows only allocated space in files linked into a directory.
bdf(1) sees the free space and can infer everything else is allocated.
