Subject: Minos candidate file removals May 13 2014

As announced and discussed since 2012,
Minos will remove from disk and tape all the Candidate files
for all reconstruction releases, both data and simulation.

These files are no longer used, and fill about half of our tapes,
roughly 430 TB in 1.6 million files.

A migration to new media is about to start,
and we do not want to move files which we will never use.

This does not affect Minos+, as we no longer write cand files.

The file removals will start May 13, 2014.
This work is tracked in https://cdcvs.fnal.gov/redmine/issues/6086

Opened service desk ticket to advise Enstore admins.

RITM0100001 05/15 FYI - removal of 430 TB, 1.6 Million files from /pnfs/minos

We have started the long promised removal of Minos 'candidate' files from /pnfs/minos.
The old files are no longer in use,
and new files of this sort are no longer being produced.

I am removing files at the rate of under 5 files per second,
to avoid overloading the Enstore servers.

Please contact minos-admin if there are any operational issues.

There will be four major removals:

reco_near
reco_far
mcout_data/*/near
mcout_data/*/far
