commit 90ff2f248097a187e6e6f2bfd3cdac71cee460c7
Author: Henrik Jess Nielsen <lrihni@egmont.com>
Date:   Tue May 26 23:22:55 2026 +0200

    Initial CSI setup — democratic-csi + NFS on int
    
    - controller.nomad: CSI controller pinned to int
    - node.nomad: CSI node plugin (int only for now, expand later)
    - volumes/example.hcl: template for creating new volumes
    
    NFS: int exports /opt/csi-volumes to 192.168.15.0/24
    Plugin ID: org.democratic-csi.nfs

+
+Nomad CSI storage for i80.dk — democratic-csi + NFS on int.i80.dk.
+
+## Architecture
+
+- **NFS server**: `int.i80.dk` exports `/opt/csi-volumes` to 192.168.15.0/24
+- **CSI driver**: [democratic-csi](https://github.com/democratic-csi/democratic-csi) v1.9.0
+- **Plugin ID**: `org.democratic-csi.nfs`
+
+## Deploy
+
+```bash
+# One-time: deploy CSI controller + node plugin
+nomad job run csi/controller.nomad
+nomad job run csi/node.nomad
+
+# Verify
+nomad plugin status org.democratic-csi.nfs
+```
+
+## Create a volume
+
+```bash
+# Edit csi/volumes/example.hcl with your id/name/size, then:
+nomad volume create csi/volumes/my-volume.hcl
+
+# Volumes are persistent — only deleted explicitly:
+nomad volume delete my-volume-id
+```
+
+## Use in a job
+
+```hcl
+volume "data" {
+  type            = "csi"
+  source          = "my-volume-id"
+  access_mode     = "single-node-writer"
+  attachment_mode = "file-system"
+}
+
+# ...in the task:
+volume_mount {
+  volume      = "data"
+  destination = "/data"
+}
+```
+
+## Expanding to all workers
+
+When ready, update `csi/node.nomad`:
+- Change `type = "service"` → `type = "system"`
+- Remove the `constraint` block
+
+Workers need `nfs-common` installed (via Ansible `storage.yml` playbook).
