RTVDSKINF would be the place to start. Failing that you could try the two items under "system health services" at

Subject: Odd DASD usage growth
We are on v7.2 on a newly implemented P9-41A (as of 2/1).
We have 10 spinning drives installed on the system, 2 are hot spares the remainder are configured in RAID 10.
Yesterday morning our disc utilization was at a tad over 34%, this morning it was over 42%. It is normal for us to get a few tenths of a percentage of growth each day, but nothing like this. Nothing new has been installed. I did find 2 new objects, but they are both very small. I know I can in theory run a RTVDSKINF and compare it to last Sunday's results, but I really don't want to run it during production hours.
I am having issues with WebSphere starting so I can't utilize Navigator. (I think it is because earlier in the week I installed Java8, but have not performed an IPL yet).
I have looked for new libraries-none, New objects-2, IFS-a few thousand few items, large spool files -none. Abnormal growth to a file-I looked a the largest/most active files-nothing stands out. I do see some growth in Peak temporary used, but that doesn't account for the growth that I see.
Any suggestions on what else I can look for?
