RE: [Condor-users] Using condor to update condor

Title: RE: [Condor-users] Using condor to update condor
On the contrary. My agreement that it would be nice to permit this software upgrade through condor channels
had the key point of doing it when each machine was ready.
Out of interest: how do the Condor Team upgrade their machines with the new versions of Condor?

If I am understanding you guys correctly, you are thinking to wait for the whole cluster to stop crunching before updating.

Now, my thought is.  Why couldn't you send a command to each node (through an admin level command), that would tell them that at the completion of their current job, update your files from folder x?  Then restart/reconfig and hook back up to the queue.  Each node would upgrade itself at the next convenient time.  That way if you have a couple nodes running some big long runs, you don't waste the clock cycles on the other machines.

/me slaps myself

condor_hold -constraint "JobStatus!=2"

It's not a config change though so requires an invocation on the
machine or from another machine with owner trust
