Hello there!
There is a problem with power save, it's experienced in SLURM 2.2.3.
When node went into NODE_STATE_POWER_SAVE and slurmctld restarted then
node will stay in NODE_STATE_UNKNOWN | NODE_STATE_POWER_SAVE forever in
slurmctld after it restarted. Solution is simple - node in that state
should be awakened so it change state from NODE_STATE_UNKNOWN to state
NODE_STATE_IDLE (if there is no error of course). Patch attached.
Andrej.
