+# EXTRA EXTRA
 
+## Secondary NFS provisioner
+
+I will add a **secondary NFS Provisioner** as a new storage class.
+
+This storage class will be targeting a **"slow"/HDD** directory/drive.
+
+Mainly intended for storing a bunch of logs, files, videos, or whatever.
+
+Looking at you Prometheus 👀👀.
+
+NFS server: nfs.filter.home
+
+Target directory: **/resources/slow_nfs_provisioner** (this is made up, I don't want to share it.)
+
+## NFS Server
+
+### Create the directory
+
+- [x] Done
+
+### Update NFS service config to allow such directory to be used.
+
+- [x] Done
+
+## Deploy new NFS provisioner
+
+```shell
+NFS_SERVER=nfs.filter.home
+NFS_EXPORT_PATH=/resources/slow_nfs_provisioner
+```
+
+```shell
+helm -n  nfs-provisioner install slow-nfs-01 nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
+    --set nfs.server=${NFS_SERVER} \
+    --set nfs.path=${NFS_EXPORT_PATH} \

+## Migrate some volumes to new dir
+
+### Prometheus
+
+(because he's the one filling my SSD.)
+
+Copy files from (maintaining permissions):
+
+**/resources/slow_nfs_provisioner/prometheus_generated_vol** to **/resources/slow_nfs_provisioner/prometheus_tmp**
+
+This is mainly to "have them" already on the destination drive, folder name can be whatever.
+
+### Create/Provision new PV
+
+Since `path` value is immutable after creation, it will require to create a new volume, move the contents to the new volume, update the configs to match the new volume, recreate the workloads, then delete the old one.
+
+Since this is my homelab, and I'm not bothered by some minutes of lost logs, I will instead, delete the old volume, delete the used deployment, create a new volume, then rename the folder `prometheus_tmp` I created on the previous step to replace the volume created (since the new volume is empty).
+
+Then restart the Kubernetes deployment.
+
+## Delete PVC
+
+```shell
+kubectl delete pvc -n observability prometheus-storage --force
+```
+
+This can take a bit since there are like 40GB of logs + it's still being used by the deployment.
+
+```shell
+kubectl get pvc -n observability prometheus-storage
+```
+
+```text

+
+### Delete Deployment
+
+```shell
+kubectl delete deployment -n observability prometheus
+```
+
+```text
+deployment.apps "prometheus" deleted
+```
+
+### Delete PV
+
+```shell
+kubectl delete pv pvc-698cf837-14a3-43ee-990a-5a34e1a396de
+```
+
+```text
+persistentvolume "pvc-698cf837-14a3-43ee-990a-5a34e1a396de" deleted
+```
+
+### Create new volume.
+
+```shell
+kubectl create -f PrometheusVolume.yaml
+```
+
+```text
+persistentvolumeclaim/prometheus-storage created
+```
+
+I later did some cleanup from the existent data cause 41GB was kind of too much for the usage I do (aka noticed that the container `prometheus-server` was taking forever to parse all the data).
+
+Later will change the configurations to reduce the retention + data stored.
