no applicable volumesnapshotter found

[mehransaeed7810]

I keep getting this error "no applicable volumesnapshotter found" whilst creating backups of pvcs.

I tried installing all CRDs, csisnapshotter, controller, configuring rbac but no luck.

I have attached the debug file in the attachments

kubectl get volumesnapshotclass

could be dupe of #8494

If you're trying to use CSI snapshots (and your storageclass is CSI-based) then Velero shouldn't be looking for a volumesnashotter plugin. Is the EnableCSI feature enabled?

[blackpiglet]

As @sseago commented, the CSI feature is not enabled.

                "containers": [
                    {
                        "args": [
                            "server",
                            "--uploader-type=kopia",
                            "--keep-latest-maintenance-jobs=3"
                        ],
                        "command": [
                            "/velero"
                        ],

@mehransaeed7810
You need to add --features=EnableCSI in the Velero deployment's server container's args array.
It should be something like this.

                "containers": [
                    {
                        "args": [
                            "server",
                            "--uploader-type=kopia",
                            "--keep-latest-maintenance-jobs=3",
                            "--features=EnableCSI"
                        ],
                        "command": [
                            "/velero"
                        ],
