[slurm-users] Reset FairShare?

[Paul Edmon]

That I don't know.  I would imagine not as it doesn't touch the job 
records.  It just touches the totals that sshare uses to compute 
fairshare.  But that's just a guess on my part.  We don't really use 
sreport for reporting, we instead use grafana and XDMod for historic data.
