I'm not using quotas so I can't test this for you, but logically this seems like it would work since gluster ultimately is bound by the rules of it's underlying filesystems. I'm just not sure how it would behave if someone tries to append or write a file that would cause an over-quota problem and, in the case of HA/AFR what would happen if quotas were turned on on one server and not on another? hopefully someone will calarify so we'll both know :)
