Re: [HTCondor-users] scheduled downtime configuration

[Michael Pelletier <Michael.V.Pelletier@xxxxxxxxxxxx>]

Hey Christoph,

I seem to remember that if START goes false, a machine will start evicting jobs. Am I remembering incorrectly?

I like this draining-to-shutdown approach, though - it's been something I've been meaning to look into, and it was nice to see it effortlessly appear in my inbox. :D

Hi Ben,

always good to hear from you :) 

Thanks for the insight, that's what I had in mund more or less, I do skip the file/startdcron part for now and just made it remote controllable through condor_config_val.

It's not very sophisticated but I put it here for whoever might be looking for something similar anyway :) 

On the workernode: 

InStageDrain = False
ShutdownTime = 0
Drain = ((InStageDrain =?= True && (time() + MaxJobRetirementTime < ShutdownTime)) || InStageDrain =?= False) STARTD_ATTRS = InStageDrain, ShutdownTime, StartJobs, $(STARTD_ATTRS) STARTD.SETTABLE_ATTRS_ADMINISTRATOR = StartJobs, InStageDrain, ShutdownTime START = (NODE_IS_HEALTHY =?= True) && (StartJobs =?= True) && $(Drain)

Remote control: 

zitpcx35701%  date -d "May 30 14:59:48 CEST 2019" +%s
1559221188

condor_config_val -name <workernode> -startd -set "ShutdownTime = 1559221188"
condor_config_val -name <workernode> -startd -set "InStageDrain = True"
condor_reconfig <workernode> -daemon startd                      

Cheers
Chris
