Storage quota per container - overlay2 backed by xfs


In my setup, docker daemon is running with overlay2 storage backed by xfs. Following this document I found that I need to mount / with pqouta option to able storage quota per container, so I edited /etc/fstab to include pquota option like /dev/md1 / xfs defaults,pquota 0 0, but I am not able to run a container like below

root@n1:~# docker run -it --storage-opt size=120G fedora /bin/bash
docker: Error response from daemon: --storage-opt is supported only for overlay over xfs with 'pquota' mount option.
See 'docker run --help'.

Do I need to follow any other steps?

Thanks in advance!!
