[gpfsug-discuss] Independent fileset free inodes

[Barry Evans]

-i will give you the exact used number but... Avoid running it during peak
usage on most setups. It's pretty heavy, like running a -d on lssnapshot.

Your best bet is from earlier posts: '-L' gives you the max and alloc. If
they match, you know you're in bother soon. It's not accurate, of course,
but prevention is typically the best medicine in this case.

Cheers,
Barry

Hmm. I'll create an RFE next week then. (just in case someone comes back
with a magic flag we don't know about!).

We have the same problem when we started using independent fileset. I
think this should be a RFE item that IBM should provide a tool similar
to 'mmdf -F' to show the number of free/used inodes for an independent
fileset.

I.e. About 8 as that was the number of child filesets.
