Description

/minos/data/mcimport uses 40 TB of the 206 TB in /minos/data.

The mcimport files are not likely to be used.
The most recent mcimport was for willhf on May 11, 2017

We need to document the mcimport process,
inventory the files, and
remove or archive the files we do not need.
See Service Desk TASK0150135 for RITM0801091 (general NAS cleanup)

Future mcimport activity should be via the /pnfs/minos/persistent area.
See https://cdcvs.fnal.gov/redmine/issues/13929
