Filesystem XFS is mounted as ext4 (fsType: ext4 / filesystem: xfs)

[0hlov3]

Describe the bug

Hi there,

we configured the Kubernetes Cluster to use XFS as Filesystem, after we deployed the Cluster everything looks as aspected.

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: sk3-standard
parameters:
  filesystem: xfs
  storageProfile: SK3 Standard

After we created the first PVCs/PVs and took a look at the PV, the fsType is ext4 and the filesystem is declared as xfs.

apiVersion: v1
kind: PersistentVolume
metadata:
  annotations:
    pv.kubernetes.io/provisioned-by: named-disk.csi.cloud-director.vmware.com
  creationTimestamp: "2022-12-09T12:53:15Z"

  persistentVolumeReclaimPolicy: Delete
  storageClassName: sk3-standard
  volumeMode: Filesystem
status:
  phase: Bound

But if we look at the node or the container the Filesystem Mounted is EXT4

❯ k exec -ti centostate-0 -- /bin/bash
[root@centostate-0 /]# df -T
Filesystem     Type    1K-blocks    Used Available Use% Mounted on
/dev/sdb       ext4        95054    1550     86336   2% /vol

Unfortunately, I don't currently understand how the filesystemtype and the fstype are related. I only see that ext4 is mounted on the nodes and on the containers.

I would like to understand here if this is an intended behavior.

Reproduction steps

1. Cloud Dorector -> Kubernetes Container Clusters -> New
2. Kubernetes Storage -> Filesystem -> xfs
3. Deploy the Cluster

Expected behavior

The expected behaviour is, that the Volumes are formatted and mounted as XFS.

@0hlov3 apologies for the delay.

@ymo24 could you please take a look at this
