Description

12       condor_preenexamines the directories belonging to HTCondor, and removes
13       extraneous files and directories which may be left over  from  HTCondor
14       processes  which terminated abnormally either due to internal errors or
15       a system crash. The directories  checked  are  the  LOG,  EXECUTE,  and
16       SPOOLdirectories  as  defined in the HTCondor configuration files. con‐
17       dor_preenis intended to be run as user rootor  user  condorperiodically
18       as  a backup method to ensure reasonable file system cleanliness in the
19       face of errors. This is done  automatically  by  default  by  the  con‐
20       dor_masterdaemon.  It  may  also  be explicitly invoked on an as needed
21       basis.
22
23       When condor_preencleans the SPOOLdirectory, it always leaves behind the
24       files  specified  in  the  configuration variables VALID_SPOOL_FILESand
25       SYSTEM_VALID_SPOOL_FILES, as given by the configuration. For the LOGdi‐
26       rectory, the only files removed or reported are those listed within the
27       configuration variable INVALID_LOG_FILESlist. The reason for this  dif‐
28       ference  is that, in general, the files in the LOGdirectory ought to be
29       left alone, with few exceptions. An  example  of  exceptions  are  core
30       files.  As  there  are  new  log files introduced regularly, it is less
31       effort to specify those that ought to be removed than  those  that  are
32       not to be removed.
