# Octopus Maintenance

## Slurm

Status of slurm

```
sinfo
sinfo -R
squeue
```

we have draining nodes, but no jobs running on them

Reviving draining node (as root)

```
scontrol
  update NodeName=octopus05 State=DOWN Reason="undraining"
  update NodeName=octopus05 State=RESUME
  show node octopus05
```

Kill time can lead to drain state

```
scontrol show config | grep kill
UnkillableStepProgram   = (null)
UnkillableStepTimeout   = 60 sec
```

check valid configuration with `slurmd -C` and update nodes with

```
scontrol reconfigure
```
