Receiving Alert "OUT OF INODES"

Greetings all that can assist,

I have been receiving a message from one of the filers stating that it is OUT OF INODES.  Yet, when I read the alert, it is basically vague as to what, where, it is out of the inodes.  The current make up of the filer is as follows:

Used: 48.92TB

Available: 78.26TB

Spare: 21.17 TB

So it is not like I am out of space and there are no volumes at 98% or higher, and I have adjusted the qtress to be all under 90%, yet the message is now cbeginning to come more frequently.

Unfortunately, our maintenance contract has yet to be signed, so I am on my own.

As always, any and all help is greatly appreciated, especially in one is drowning...

Thanks

James
