Name
condor_preen remove - extraneous files from HTCondor directories
Synopsis
condor_preen [-mail] [-remove] [-verbose] [-debug]
Description
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.
Options
-mail
Send mail to the user defined in the PREEN_ADMIN configuration variable, instead of writing to the
standard output.
-remove
Remove the offending files and directories rather than reporting on them.
-verbose
List all files found in the Condor directories, even those which are not considered extraneous.
-debug
Print extra debugging information as the command executes.
Exit Status
condor_preenwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1
(one) upon failure.
