Introduction:
------------
On the ppcc computer (rich.pppl.gov as of 17-Feb-2004), certain
disk partitions tend to get pretty full.  These must be checked
periodically, and some action taken.

The most likely disk-space problems will be in:
  /export/home/
and
  /data/

Each of these partitions is addressed below ...

/export/home/
-------------
  o /export/home/pceic (~pceic home directory)
  o Other user directories

  Details:
  o /export/home/pceic (~pceic home directory)
    This includes all of the "d.o" files in ~pceic/rtc, which are
    created by the psrtc program (rtc860 or whatever).
    Older "d.o" files must be compressed using gzip.
      > su -
      # cd ~pceic/rtc
      # gzip d_109*.o

    Periodically, the oldest of these will be copied to /data/psrtc
    and deleted from the local directory.
      > su -
      # cd ~pceic/rtc
      #
      # cp d_108*.gz /data/psrtc/
       -OR-
      # tar cf - d_108*.gz | (cd /data/psrtc ; tar xvf -)
      #
      # /bin/rm d_108*.gz

  o Other user directories
    Just keep an eye on them ...

/data partition
---------------
/data holds
  o pcs "s" files
  o compressed "d.o" files copied from ~pceic/rtc
  o other stuff

  Details:
  o pcs "s" files:
      Files for cpu1 (s*_cpu1.dat) can be deleted outright.  In fact,
      the "operator's setup data" should specify that the cpu1 s-file
      should not be saved

      As for files from cpu2 and cpu3, shots which did not use
      rtefit can probably be deleted.  Check with a
      knowledgeable and caring "pic" (like David Gates or Dennis
      Mueller) before deleting.

  o compressed "d.o" files copied from ~pceic/rtc
      When a lot of these accumulate, they are copied to the unix
      cluster via ftp and then deleted locally.

      Example of moving files for shots 105* from rich to unix cluster:

        On unix cluster:
        - Make sure that directory /p/nstxusr1/psrtc/105 exists;
        - Make sure that you can write to it!  Grp owner should
          be nstx_sw, with "write" access allowed to "group".

        On ppcc (rich.pppl.gov)
        > su -                #become root
        # cd /data/psrtc
        # ftp taurus
        Name: xyz
        Password: xxxx
        ftp> cd /p/nstxusr1/psrtc/105
        ftp> bin              #Binary transfer mode
        ftp> prompt
        ftp> mput d_105*.gz
        ftp> quit
        #
        # /bin/rm d_105*.gz   #Delete transferred files
