Re: diskspace

Hi,

Please post the output of

du -sk /app

If there is a difference, then please let us know if you have recently deleted any large file

If yes, then this might be an issue with the files which is deleted but still unlinked since the DB was using it

NOTE: Bdf shows linked and unlinked files while du only shows linked files.

You could be able to find the PID is you have the crashinfo tool which you could get from HP on request

# ./crashinfo -ulinked

Thanks,
Avinash

Re: diskspace

As adviced, there are unlinked files,
You need to get the crashinfo which will help you to find the PID which is accessing the ulinked file

Stopping your application which accesses this FS will resolved the issue.

Re: diskspace

I believe there is an option

# lsof -L
that will list the link counts of open files.
If the Link count is 0 then those are unlinked files
You could use the option to list all files and look for a zero
link count in the NLINK column

Re: diskspace

http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.81/man.html

+|-L [l] This option enables (`+') or disables (`-') the
listing of file link counts, where they are avail-
able - e.g., they aren't available for sockets, or
most FIFOs and pipes.

When +L is specified without a following number,
all link counts will be listed. When -L is speci-
fied (the default), no link counts will be listed.

When +L is followed by a number, only files having
a link count less than that number will be listed.
(No number may follow -L.) A specification of the
form ``+L1'' will select open files that have been
unlinked. A specification of the form
``+aL1 '' will select unlinked open
files on the specified file system.
