I set 200GB limit to one user and 100GB to another user.

as soon as I reached 139GB and 53GB each, hitting the quota errors.
anyway to workaround quota functionality on btrfs LZO compressed
filesystem?

Please paste "btrfs qgroup show -prce <mnt>" output if you are using btrfs
qgroup/quota function.

And, AFAIK btrfs qgroup is applied to subvolume, not user.

So did you mean limit it to one subvolume belongs to one user?

Thanks,
