Hi all,

Linux help needed: I wonder if is possible to move just EXECUTE path (generally placed in /var or LOCAL_DIR) to a different location with better hardware requirements (basically more disk space to execution files). 

If I change value of this variable at condor_config (master config) and run condor_reconfig, the nodes refresh their local config correctly but when I submit a test job, it stay at held status forever. 

Condor_q -analyze reasons: lost logs by references to their original locations  (which I never change because I don't need that)

I prefer to change just execution place because if I change more important global variables as e.g. LOCAL_DIR, I am forced to configure more variables.

Is there any "elegant" way of move this location post installation that reconfigure execution?

Thanks!!!

    Hi Alex, 
    
    You can change the location of EXECUTE alone; no need to change
    LOCAL_DIR.
    
    Some advice:
    
    You cannot change the location of EXECUTE on-the-fly with just
    condor_reconfig.  You will need to restart HTCondor on each node
    where you change the location of EXECUTE, by either restarting the
    HTCondor service (i.e. systemctrl restart condor) or with
    "condor_restart -master".   If you are running HTCondor v9.x or
    above, then the upon restarting, the condor_master will create the
    EXECUTE directory in the new location for you with the proper
    ownership/permissions.  If you are running an older version of
    HTCondor, then you will need to create the EXECUTE directory
    yourself with the same ownership/permissions as the original EXECUTE
    directory.
    
    It is advised you keep EXECUTE on a local filesystem If you are
    trying to relocate EXECUTE onto a shared filesystem, such as an NFS
    volume with root-squash enabled, you will need to chown EXECUTE to
    permissions 1777.  See details here:

    Hope the above helps,
    Todd
