.. When i deploy the pod, I always get the following error
But if I go with only 1 PVC for both the mounts it is working fine.. Could anyone please let me know what is happening..

Answer 1

There is a 1-to-1 mapping between PhysicalVolumes and EFS storage.
If you use two different EFS with volumeHandle: fs-XXXXX and volumeHandle: fs-YYYYY it will work.
