I don't know that I have a truly compelling argument in favor of letting
pbs_server continue running in this particular scenario. The two points
I might make about that are:
* what happens when something like this happens "in flight"?
IIRC, pbs_server continues happily along, although I don't
recall what the node looks like. (offline? down?)
* if the preferred mechanism for managing nodes is qmgr versus
editing the nodes file, you've got a chicken-egg problem (can't
get pbs_server to run, so can't get it to expunge the bad node).
Not strong arguments, I'll grant you. For what it's worth, the error
message is clear, the resolution is simple, so this is certainly nothing
more than personal preference.
