@joaquin Hi. While the reclaim policy of my the PVs are set to Delete in my case, I am pretty sure that it may not be the problem cause even after restarts, the same PV is used by the PVC and the PVC is also bound to the POD properly but still to validate your assumption, I did give it a test.
With Reclaim policy as Delete
PV and PVC
ALPHA POD
Storage class:
With Reclaim policy as Retain
But I still get the same errors as mentioned.
