/sapmnt/SID is inconsistent with used space
Hi SAP gurus,
I have a problem with our production system with the directory /sapmnt/P01
when I issue the command df -h it shows that the directory has already accumulated 21G of space.
/sapmnt/P01 24G 21G 2.9G 88% /sapmnt/P01
but when I issue the command du -sh for this directory it only shows 9.3G of data is only being used
bash-3.00$ du -sh
inside the directory
bash-3.00$ du -sh *
There is a difference of almost 11G of space used. There is no problem with the global directory since it is only 8.7G of data. Can anyone shed some light on where the 11G of data is?
Thank you and hoping you can help me.

Yes, if this is an open file handle issue or if you can find out (see below) the particular process which has opened the file handle .. you can just restart this one.

Of course you can find it (by scanning the open file handles), but the implementation of "lsof" is very OS dependent.
