Astra Trident 24.10.0

Issue

Following upgrade to Trident 24.10, you can see "permission denied" errors on existing ontap-nas-economy PVCs.

Doing an ls in /var/lib/kubelet/pods on an existing mounted PVC would show as follows:

d????????? ? ? ? ? ? mount

 
Pods can be stuck on terminating as it was unable to destroy them due mount point reporting as lacking permissions.
Manually trying to mount it on another point failed directly with nfsv3, and with nfsv4 it gave same ?????? output.
 
trident log shows:
level=error msg="GRPC error: rpc error: code = Internal desc = could not check if the target path (/var/lib/kubelet/pods/POD_UID/volumes/kubernetes.io~csi/pvc-UID/mount) is a directory; stat /var/lib/kubelet/pods/POD_UID/volumes/kubernetes.io~csi/pvc-UID/mount: permission denied" logLayer=csi_frontend requestID=REQUEST_UID requestSource=CSI
