Hi, since we updated our site from Slurm 24.11 to Slurm 26.05.4 the idle~ (powersaved) nodes goes to state unk (unknown) whenever running scontrol reconfigure. This state is not cleaned by Slurm itself. Is this a known issue of Slurm 26.05? Best, Stefan

Yes it is! We were hit by this regression in 26.05.4, see the ticket https://support.schedmd.com/show_bug.cgi?id=25750 I hope that the fix will be included in 26.05.5. We have had to disable power saving until this issue has been resolved. Best regards, Ole -- Ole Holm Nielsen PhD, Senior HPC Officer Department of Physics, Technical University of Denmark
Hi, Could someone share the (buggy) traces of the sinfo/squeue commands , in this format? https://github.com/qtop/qtop/blob/c89c85425197a63c40c58d63379e93ffbfbf9a1d/q... I would help: A fellow in Boston would make the detection of that node state more visible in said tool. BR, F.
