## Conclusion ## Conclusion
Using Clonezilla to clone to a smaller disk is a safe and reliable method to shrink VMDK files without touching VMX files directly. While it requires more steps than the manual approach, it reduces the risk of configuration errors that could leave your VM unbootable. As always, keep backups before attempting any disk resizing operations.

### Configless mode ### Configless mode
Since Slurm 20.02, it supports a configless mode, which means that you don't need to create a `/etc/slurm/slurm.conf` file on each node, instead, you can use the `slurmctld` to distribute the configuration to all nodes.
