remove extraneous files from HTCondor directories
condor_preen [-mail ] [-remove ] [-verbose ] [-debug ] [-log <filename>]
condor_preen examines 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
SPOOL directories as defined in the HTCondor
configuration files. condor_preen is 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_master daemon. It may also be explicitly
invoked on an as needed basis.
When condor_preen cleans the
SPOOL directory, it always leaves
behind the files specified in the configuration variables
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
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_ADMINconfiguration variable, instead of writing to the standard output.
- Remove the offending files and directories rather than reporting on them.
- List all files or directories found in the Condor directories and considered for deletion, even those which are not extraneous. This option also modifies the output produced by the -debug and -log options
- Print extra debugging information to stderr as the command executes.
- -log <filename>
- Write extra debugging information to <filename> as the command executes.
condor_preen will exit with a status value of 0 (zero) upon success, and it will exit with a non-zero value upon failure. An exit status of 2 indicates that condor_preen attempted to send email about deleted files but was unable to. This usually indicates an error in the configuration for sending email. An exit status of 1 indicates a general failure.
