DF / DU open file descriptor problem on CFS mounted directory

Morning all! My linuxquesitons cherry is now being popped!

please be gentle! lol

i am having issues with a cfs mounted directory whereby i have oracle 11.g archive and trace logs being saved.

prob is this...

[root@waldorf emit]# du -h /archive
4.7G /archive/infodb/archivelog
9.1G /archive/infodb
38G /archive/emit/archivelog
85G /archive/emit
94G /archive

[root@waldorf emit]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/mpath0p7 187G 157G 31G 84% /archive

this is replicated across both nodes.

now ive googled and read up on some clever stuff relating lsof | grep (various strings)

having been presented with page after page full of PID info i dont seem to be getting too far.

examples i have tried lsof | grep deleted
lsof | grep archive
lsof | grep emit

my enterprise manager is seeing the space as per the df command and thus is now warning about low file space.

how do i identify the files that are not quite deleted? a simple node restart does not fix this issue (tried that one last week)

thanks as always for any help offered / received

have tried the following to try and ascertain what PID's may be locking this directory and available space...

fuser /dev/mapper/mpath0p7
fuser /archive

on 2 different but connected servers. upon running the above i received no output whatsoever.


df, du, file, open
