6. Formats the workers' dedicated `scsi1` disk (ext4, if not already formatted) and mounts it at `/mnt/longhorn-extra` (via `/etc/fstab`) — this is the disk `03-k8s-infra` later registers as an extra Longhorn disk, to keep Longhorn off the root filesystem and avoid `DiskPressure`

Worker nodes get an extra `longhorn-extra` disk at `/mnt/longhorn-extra` (a dedicated mount set up by `k8s-bootstrap`, patched onto the Longhorn `Node` CR here) so Longhorn data stays off the root disk and doesn't cause `DiskPressure`. `nodeDownPodDeletionPolicy` deletes both the StatefulSet and Deployment pod on node-down so stateful workloads reschedule automatically |
