[slurm-users] ReqNodeNotAvail, but none of nodes in partition are listed.

[Prentice Bisbal]

Dang it. That's it. I recently changed the default time limit on some of 
my partitions, to only 48 hours. I have a reservation that starts on 
Friday at 5 PM. These jobs are all assigned to partitions that still 
have longer time limits. I forgot that not all partitions have the new 
48-hour limit.

Still, Slurm should provide a better error message for that situation, 
since I'm sure it's not that uncommon for this to happen. It would 
certainly result in a lot less tickets being sent to me.

I have spent the majority of my day investigating this, but haven't turned up anything meaningful. Both jobs show the "ReqNodeNotAvail" reason, but none of the nodes listed at not available are even in the partition these jobs are submitted to. Neither job has requested a specific node, either.
