Re: [HTCondor-users] CondorCE with Condor HA setup broke

An HA configuration for the Condor LRMS should not be an issue for the CE. I also wouldnât expect real jobs to fail when trace jobs succeeded. I assume excerpt [1] is from the CE SchedLog and [3] from the LRMS Condor configuration?

The messages in [1] donât look like a problem. I expect to see them, since the CE doesnât have a startd or negotiator. Do you see anything else in the logs thatâs indicative of a problem? Is the Job Router failing to contact the LRMS schedd?
