You can use the mmlsfileset DEVICE -L option to see the maxinodes and allocated inodes. I have a perl script that loops through all of our file systems every hour and scans for it. If one is nearing capacity(tunable threshold in the code), it automatically expands it by a set amount(also tunable). We add 10% currently. This also works on file systems that have no filesets as it appears as the root fileset.
I can check with my boss to see if its ok to post it if you want it. Its about 40 lines of perl.
