Hello Manuales,

with bdf -i you can view the number of used and free inodes on your file system.

For more info see kb doc UPERFKBRC00009350 -http://www4.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c01030840-1

regards,

Hi Manuales:

Why bother? If you are running VxFS filesystems (and that's the default for everyone but '/stand') then inodes are allocated as needed, essentially without limit. If 'largefiles' isn't enabled, then your ceiling for the filesystem's inodes would be ~2G but with a 'largefiles' filesystem your limitations are non-existent for all purposes.

Regards!

You can use Openview Operation to monitor
Take a look at the monitor and script shipped with OVO:

The monitor itself is called disk_util and the script is called disk_mon.sh (it can be found in the /var/opt/OV/bin/OpC/monitor directory if it has been distributed to the node).
It should be able to adopt this for ones needs (i.e. use df -g and the "free files" vs. "total files" columns).

Anyway, if you are using vxfs filesystem, nothing to worry about.
