condor_preen remove - extraneous files from HTCondor directories
condor_preen [-mail] [-remove] [-verbose] [-debug]
condor_preenexamines the directories belonging to HTCondor, and removes
extraneous files and directories which may be left over from HTCondor
processes which terminated abnormally either due to internal errors or a
system crash. The directories checked are the LOG , EXECUTE , and SPOOL
directories as defined in the HTCondor configuration files. condor_preenis
intended to be run as user root or user condor periodically as a backup method
to ensure reasonable file system cleanliness in the face of errors. This is
done automatically by default by the condor_masterdaemon. It may also be
explicitly invoked on an as needed basis.
When condor_preencleans the SPOOL directory, it always leaves behind the files
specified in the configuration variables VALID_SPOOL_FILES and
SYSTEM_VALID_SPOOL_FILES , as given by the configuration. For the LOG
directory, the only files removed or reported are those listed within the
configuration variable INVALID_LOG_FILES list. The reason for this difference
is that, in general, the files in the LOG directory ought to be left alone,
with few exceptions. An example of exceptions are core files. As there are new
log files introduced regularly, it is less effort to specify those that ought
to be removed than those that are not to be removed.
- Send mail to the user defined in the PREEN_ADMIN
configuration variable, instead of writing to the standard output.
- Remove the offending files and directories rather than
reporting on them.
- List all files found in the Condor directories, even those
which are not considered extraneous.
- Print extra debugging information as the command
condor_preenwill exit with a status value of 0 (zero) upon success, and it will
exit with the value 1 (one) upon failure.
