Choosing Glusterfs volume type

Hi Rancher devs. First of all I would like to thank you all for the nice work you’ve done. The glusterfs persistent storage is such an helpful feature. But I have one question about it. Despite the automated set up via the catalog using a default 3x replication mode, is is possible to choose in a feature release the volume mode? A Distributed-Replicated volume wich behaves like a RAID 10 would be great, the possibility to run a RAID5 like dispersed volume would be nice as well to get a low disk usage overhead. Once again thank you. Charles.
