ReadOnlyMany does not work with static provisioning

Open przem123 opened this issue 5 years ago • 7 comments

As a system admin I created the following static pv:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-images
  labels:
    id: images
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadOnlyMany
  csi:
    driver: ibm-spectrum-scale-csi
    volumeHandle: 17399599334479190260;099B6A42:5DC52700;path=/mnt/remote_fs0_1m/static/images

Unfortunately, a user can still write to the PV if he mounts the volume. This should not be allowed.

Please fix it as it affects my AI workloads.

Will you support ReadOnly Volumes for static provisioning in 2.0.0?

przem123 avatar May 25 '20 17:05 przem123

No, There is no support of ReadOnly volumes in 2.0.0

The idea of this issue is to deliver this functionality in CSI, so please reopen and implement it in the next release. The functionality should be supported.

przem123 avatar May 25 '20 22:05 przem123

Currently there is no way to support this but keeping this open as requirement.

Thanks @deeghuge.

Maybe you could call mmchattr -i yes fileOrDir for a static volume and then reset it again for deletion.

Very good suggestion. I will look into It.
