[slurm-users] Effect of slurmctld and slurmdb going down on running/pending jobs

Just in case, increase Slurmdtimeout in slurm.conf (so that when the 
controller is back, it will give you time to fix the issues with the 
communication between slurmd and slurmctld - if there will be any). 
Otherwise it should not affect running and pending jobs. First stop 
controller, then slurmdbd. And then when the disk arrangements are done, 
first start slurmdbd and then slurmctld.
