##### 2.4 Modifying MountOptions in Storageclass and PersistentVolumes
|
||||
|
||||
CephCSI, starting from release v3.9.0, will pass the options specified in the
|
||||
StorageClass's `MountOptions` during both `NodeStageVolume` (kernel cephfs or
|
||||
ceph-fuse mount operation) and `NodePublishVolume` (bind mount) operations.
|
||||
Therefore, only common options that is acceptable during both the above
|
||||
described operations needs to be set in StorageClass's `MountOptions`.
|
||||
If invalid mount options are set in StorageClass's `MountOptions`
|
||||
such as `"debug"`, the mounting of cephFS PVCs will fail.
|
||||
|
||||
Follow the below steps to update the StorageClass's `MountOptions`:
|
||||
|
||||
- Take a backup of the StorageClass using
|
||||
`kubectl get sc <storageclass-name> -o yaml > sc.yaml`.
|
||||
- Edit `sc.yaml` to remove the invalid mount options from `MountOptions` field.
|
||||
- Delete the StorageClass using `kubectl delete sc <storageclass-name>`.
|
||||
- Recreate the StorageClass using `kubectl create -f sc.yaml`.
|
||||
|
||||
Follow the below steps to update the PersistentVolume's `MountOptions`:
|
||||
|
||||
- Identify cephFS PersistentVolumes using
|
||||
`kubectl get pv | grep <storageclass-name>`.
|
||||
- and remove invalid mount options from `MountOptions` field
|
||||
in the PersistentVolume's using `kubectl edit pv <pv-name>`.
