Uninstall Rook Ceph

To completely remove Rook Ceph you must remove the app and clear all the environment configurations to prevent an automatic reinstall.

Remove the application by running the script:

source /etc/platform/openrc
system application-remove rook-ceph --force
retry_count=1
retries=200
while [ $retry_count -le $retries ]; do
    rookstatus=$(system application-list | grep rook-ceph | awk '{print $10}')
    echo $rookstatus
    if [[ "$rookstatus" == "uploaded" ]]; then
        system application-delete rook-ceph --force
        break
    fi
    echo "Retry #" $retry_count
    let retry_count++
done

Remove the environment configurations completely.
1. Remove .
  1. Lock the host.
```
~(keystone_admin)$ system host-lock <hostname>
```
  2. List all to get the uuid of each .
```
~(keystone_admin)$ system host-stor-list <hostname>
```
  3. Remove each using the uuid of all .
```
~(keystone_admin)$ system host-stor-delete <uuid>
```
2. Remove the storage backend ceph-rook.
```
~(keystone_admin)$ system storage-backend-delete ceph-rook-store --force
```
3. Remove host-fs.
  1. Check host-fs status.
```
~(keystone_admin)$ system host-fs-list <hostname>
```
  2. To remove a host-fs, the filesystem needs to be in Ready state. To release an In-Use host-fs, remove all functions from it and reapply the application:
```
~(keystone_admin)$ system host-fs-modify <hostname> ceph --functions=
~(keystone_admin)$ system appliction-apply rook-ceph
```
  3. When the host-fs is in Ready state, remove the host-fs:
```
~(keystone_admin)$ system host-fs-delete <hostname> ceph
```
4. ( Only) Remove controller-fs.
  1. Check controller-fs status.
```
~(keystone_admin)$ system controller-fs-list
```
  2. To remove a controller-fs, the standby controller must be locked and the controller-fs needs to be in Ready state.
```
~(keystone_admin)$ system host-lock <hostname>
```
  3. To release an In-Use controller-fs, remove all functions from it and reapply the application.
```
~(keystone_admin)$ system controllerfs-modify ceph-float --functions=
~(keystone_admin)$ system appliction-apply rook-ceph
```
  4. When the controller-fs is in Ready state, remove the host-fs.
```
~(keystone_admin)$ system controller-fs-delete ceph-float
```
