"Permission Denied" on ODF CephFS RWX Volumes with Custom SCCs
Issue
-
Pods in a multi-replica deployment using a ReadWriteMany (RWX) PersistentVolumeClaim (PVC) on ODF CephFS are unable to access the shared volume concurrently.
-
Typically, only one pod (often the last one to start) can access the volume mount, while all other pods receive Permission denied errors.
