The nodes can be upgraded in any order. However, since 8.8.15 is a security release that addresses problems in the collector and schedd, it would be wise to upgrade your Central Manager and Submit nodes first. As stated earlier, upgrading these nodes should
have little effect on jobs.
Depending on what you want to accomplish: 1) you can upgrade your execute nodes and running jobs on that node will be interrupted and started on another node, or 2) you could drain an execute node of jobs and then upgrade it.

Stopping the central manager will have no effect on running jobs. It will prevent new jobs from starting until it comes back up. Stopping the submit node will not kill jobs if you have job leases turned on (they are by default, IIRC) and the schedd comes up before the lease expires. - ToddM _______________________________________________ HTCondor-users mailing list To unsubscribe, send a message to htcondor-users-request@xxxxxxxxxxx with a subject: Unsubscribe You can also unsubscribe by visiting https://lists.cs.wisc.edu/mailman/listinfo/htcondor-users The archives can be found at: https://lists.cs.wisc.edu/archive/htcondor-users/ |
