CESM1.0.z and CESM1.1.z - Major problem when running any scripts in the $DOUT_S_ROOT directory while the short term archiver is

[aliceb]

Affected Releases - CESM1.0.z and CESM1.1.z(Bugzilla 1875) There is a known and potentially severe problem that can remove all your data in the short term archive directory ($DOUT_S_ROOT) accidently. This could cause you to lose your model data forever. The problem occurs in CESM1.0.z and CESM1.1.z. when

- the short term archiver is running as part of a case
AND
- diagnostics or post-processing scripts are accessing the same short term archive directory

This problem has been fixed in CESM1.2.z.For CESM1.0.z and CESM1.1.z, we currently recommend that users never run diagnostics or post-processing packages in the same location as the short-term archiver when the short term archiver is active.Another option in CESM1.0.z and CESM1.1.z is to replace the following code segment at the end of the scripts/ccsm_utils/Tools/st_archive.sh script:Old Code (lines 305-306):

mv ${sta}/* ${DOUT_S_ROOT}
  rm -fr ${sta}

New Code (lines 305-312):

if mv ${sta}/* ${DOUT_S_ROOT}; then
     rm -fr ${sta}
  else
     echo "st_archive.sh: error, final move command unsuccessful"
     echo "               some short-term archive data may be in ${sta}"
     echo "st_archive.sh: exiting"
     exit 1
