# 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
```
## Password management
So we create a script that can deploy files from octopus01 (head node). Unfortunately ids in passwd do no match, so we can't copy those yet.
See /etc/nodes for script and ssh files, sudoers (etc)
Basically the root user can copy across.
