Hi all
After screwing my infra with the update to 4.2 (probably a bad manipulation), i am planning a rebuild of the entire infra. First i want to replace my NFS storage with a glusterfs storage. All documentation tell me that i need 3 hosts.. but for the moment i only have 2 but planning to had more later.
So does it make sense to start with 2 hosts and use glusterfs as the storage domain(lets says with a replicate of two with all its limitations). If it make sense, 1- what is the best way to do it. 2- how hard will it be to had the 3rd host when available and make it replica 2+arbiter.
Also in a setup where i have 3 hosts (replica 2+arbiter) does all the 3 hosts can run users vm?
Thanks for your inputs.

Some question about the arbiter box. 1- Lets says i am using a old box for the arbiter with minimum spec. Do i need to mark it as a arbiter box? Does the installer scripts need to know that it is a arbiter box? 2- When i get my hand on new host for running VM. Do i need still need the arbiter box?

Hi carl, During deployment via cockpit+gdeploy plugin when you input the host, host in the third text box will be considered as Arbiter host. Thanks kasturi On Tue, Jan 9, 2018 at 11:26 PM, carl langlois <crl.langlois@gmail.com> wrote:

The dependent bug on allowing single node gluster volume will suffice for manual deployment - that is, provision the gluser volumes using a gdeploy configuration file. There are further changes needed to ensure that the Cockpit UI based deployment supports single node gluster deployment.
