What distro are you running on your servers?

    Yes. Because the LTS 2.12 comes with zfs 0.7, which does not support
    project quota. We tested several 2.14 versions, at first thought the
    project quota on ZFS is not ready at all, later find out it works on
    new directory but not existing one.

    Thank you! This lustre is intended to replace an old Glusterfs that
    performed badly due to various of issues, including space and inode
    quota not working properly. Project quota is a must have feature. It
    hasn't been put into production yet. We are waiting for Lustre 2.15.
