Hi Leonardo,

Currently we don't have any method to import any back-end FS's quotas 
into gluster.

No, its not possible (at least) as of now. By the way using ext4 
back-end and creating gluster volumes on existing data node is not 
***recommended**. *

Gluster quota doesn't impair back-end FS quota behaviour, but gluster 
knows nothing about that, so you can't have a volume wide quota 
implementation.

No, only way to manage gluster quota is from glusterd (gluster 
management daemon) commands.

No.
