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.

Re: [ovirt-users] Rebuilding my infra..
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?

For the third it can be pretty much anything capable of running as an arbiter. +1 the arb box can be an old SFP core2duo with a 40-60 GB SSD for most cases. The formula is something like 4k of arbiter space for every "file".

[ovirt-users] Rebuilding my infra..
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.
