feat(zfspv): adding snapshot and clone support for ZFSPV (#39)
This commits support snapshot and clone commands via CSI driver. User can create snap and clone using the following steps.
Note:
- Snapshot is created via reconciliation CR
- Cloned volume will be on the same zpool where the snapshot is taken
- Cloned volume will have same properties as source volume.
-----------------------------------
Create a Snapshotclass
```
kind: VolumeSnapshotClass
apiVersion: snapshot.storage.k8s.io/v1beta1
metadata:
name: zfspv-snapclass
annotations:
snapshot.storage.kubernetes.io/is-default-class: "true"
driver: zfs.csi.openebs.io
deletionPolicy: Delete
```
Once snapshotclass is created, we can use this class to create a Snapshot
```
apiVersion: snapshot.storage.k8s.io/v1beta1
kind: VolumeSnapshot
metadata:
name: zfspv-snap
spec:
volumeSnapshotClassName: zfspv-snapclass
source:

Create a clone volume
We can provide a datasource as snapshot name to create a clone volume
```yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: zfspv-clone
spec:
storageClassName: openebs-zfspv
dataSource:
name: zfspv-snap
kind: VolumeSnapshot
apiGroup: snapshot.storage.k8s.io
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 4Gi
```
It will create a ZFS clone volume from the mentioned snapshot and create the PV on the same node where original volume is there.
Here, As resize is not supported yet, the clone PVC size should match the size of the snapshot.
Also, all the properties from the storageclass will not be considered for the clone case, it will take the properties from the snapshot and create the clone volume. One thing to note here is that, the storageclass in clone PVC should have the same poolname as that of the original volume as across the pool, clone is not supported.
