I will be taking this host down for maintenance tomorrow. I don't know if
EDEX keeps any processed HDF5 files.

What I wonder is if 55,000,000 is a sufficient amount of inodes for basic
EDEX installations.

I have had problems before on a filesystem which we moved to zfs. After
that,  we no longer saw any I/O hangs. I'm hoping a good purge, tomorrow,
on the /data_store/ directory will get the host back to "acting normal"
(aka no more high loads and I/O hangs). The Geosciences department which
asked for access to an EDEX server isn't yet using it in the classroom!
