I’m having a simple trouble updating my block storage using resize2fs.
The error message sounds quite simple and straight forward, but I have no clue to solve this problem.

$ kubectl exec -it es-prod-es-default-0 -n namespace -- /bin/bash

$ df -hT

elasticsearch@es-prod-es-default-0:~$ df -hT

Thanks for your help in advance!
