While the quota tracks space usage for a subvolume, once it's reached,
writes fail. I'm not sure what interface exists for applications to
learn whether a quota is set and what value. I've noticed that ext4,
xfs, btrfs each have their own quota implementation and they're all
kinda confusing in different ways.

Any way to achieve what I'm trying to do then? Maybe I should ask on the MythTV mailing list.

Thanks,
