I am creating the below mongodb statefulset which creates 3 replicas but when I run the code I get the below error and all pods are in CrashLoopBackOff state.
This is the error which I get when I try kubectl create -f

clusterName: rook--smallfiles is not supported in newest mongo (4.2) you can check it in doc, you are not specifying image tag so newest latest is pull in this case mongo 4.2.
If you set image: mongo:4.0 your configuration should be correct.
Try removing the small file or else please try the block below i have provided.
