- I’m not sure about what you are asking for the first question, but the Gluster Fs is setup in 3 host, and the convoy part is active on all the hosts. The limitation is one pool by environment.

- The Gluster Fs will create a 3 host Gluster FS with replication on each host. You get only one gluster volume but you can virtually put all the docker volume you want inside.
- Yes you can do backup but I don’t know how exactly.
Actually the Gluster FS is really really slow with Rancher. So I can’t recommend it. Better using convoy with NFS for example : Convoy-gluster on specific storage hosts
