[slurm-users] active reservation lost when increasing the duration

[Danny Marc Rotscher via slurm-users]

Dear All,

we are running Slurm 23.11.8 and I loose an active reservation and the jobs 
running in that reservation, when I tried to increase the duration of that 
reservation.
I only want to tell you, that you may not run into the same problem.

Kind regards,
Danny Rotscher

[slurm-users] Slurmdbd purge and reported downtime

[Davide DelVento via slurm-users]

I am confused by the reported amount of Down and PLND Down by sreport.
According to it, our cluster would have had a significant amount of
downtime, which I know didn't happen (or, according to the documentation
"time that slurmctld was not responding", see
https://slurm.schedmd.com/sreport.html)

Could it be my purge settings causing this problem? How can I check (maybe
in some logs, maybe in the future) if actually slurmctld was not
responding? The expected long-term numbers should be less than the ones
reported for last month when we had an issue with a few nodes

Thanks!
