[Halla_running] Please write ROOT files to /fs/work1/

[Ole Hansen]

As already mentioned in a couple of messages earlier today, /adaqfs/home
almost filled up this morning. If that disk is full, everything stops,
so we want to prevent this.

One reason for full home directories is that people dump their analysis
results (=ROOT files) there. This is a very bad idea, not only because
the disk will inevitably fill up, but also because that disk is
relatively slow and because these files will clog the nightly backups of
the home directories.

Therefore: Please write ALL replay output to one of these locations

/fs/work1/dvcs
/fs/work1/gmp

Feel free to create your own subdirectory under either of these as
needed. We currently have 14 TB of space available. If this isn't
enough, we could round up another 19 TB on short notice. This is what
you want. It's bigger and faster.

Additionally, you may write large files to any of these locations

/adaqfs/scratch      (700GB, pretty slow, RAID5)
/aonl1/work1         (900GB, faster than scratch, RAID1)
...
/aonl4/work1

Use these only for non-analysis purposes, e.g. staging of backups before
writing to MSS, tests, scratch files, etc. Typically, anything found on
these disks may end up disappearing quickly after the end of the current
run period.
