[slurm-users] scontrol return values

[E.S. Rosenberg]

Hi fellow slurm users,

Today I noticed that scontrol returns 0 when it denies a drain request
because no reason was supplied.
It seems to me that this is wrong behavior, it should return 1 or some
other error code so that scripts will know that the node was not actually
drain.

Thanks,
Eli
