[HTCondor-users] scheduled downtime configuration

["Beyer, Christoph" <christoph.beyer@xxxxxxx>]

Hi condor-team et al,

I am looking for some input for a common task I think. We do have scheduled downtimes and I want to drain the workernodes to a point in time more or less 60 min before the official downtime begins. 

My initial idea is to come up with a classadd that defines the rest of the uptime of the machine or the point in time when the machine will go down and then alter the start definition to only accept jobs that have a requested runtime smaller than the uptime of the workernode. 

I think out of the back of my head that at least partly I have seen something similar in a request string once but can't find it anywhere, hence as I don't want to reinvent the wheel my question is wether there is a potentially usable host classadd already or a condition/requirement string that can be used to get the described behaviour ??? 

Best
Christoph
