| ### Shared home directory | ||

| By default, the Slurm appliance will spin up a local NFS server and mount the home directories to it. When using Manila + CephFS for the home directory instead, this will need to be disabled. |

This is all a bit confused TBH:
- It does not "spin up a local nfs server"; it configures the control node as an NFS server
- It does not "mount home directories to it", it "exports a directory which is mounted on the other cluster nodes as /home".

Thanks, I've changed to use these descriptions

No (for starters, that will break compute-init).
- Set tf var home_volume_provisioning to "none" and that will automatically disable the NFS mount to.
- If you don't want/aren't using compute-init or any other nfs shares at all, you can remove
nfsfrom yourgroupsfile. But in either case you don't need to mess withnfs_configurations.

Thanks for the corrections, I've updated the instructions. Do they look right now?

| Set the Tofu variable `home_volume_size = 0` to stop Tofu from creating a new home volume. NB: If the control node has already been deployed, re-running Tofu will delete the home volume and delete/recreate the control node. |
