failure to deploy docker container when enforcing storage limit on the container when the underlying disk storage for container is not on the root partition

[skmonga]

This issue is observed when deploying containers through Violet with storage limit enforced using the options --storage-opt size=xM . The underlying disk storage for docker images , containers etc is not on the root partition. A separate xfs filesystem is mounted and /var/lib/docker is symlinked to it. The container deployment fails as the xfs filesystem is mounted with defaults and doesn't support setting up pquota on individual containers.

A solution that worked for me is to specify the pquota option in /etc/fstab file for this xfs filesystem.
