the host arbiter can be even just a Raspberry PI as far as I can tell. Adding Sahina.

It can be good idea: 2 physical nodes with local disks (raid6) as gluster bricks + 2 kvm vms with pcs and drbd for arbiter.
Just be sure to not run the kvm vms arbiters on the same real hosts or it may become a mess.
I'll test it.

Yes, I checked it but it seems I still need three nodes - 2 for storage and one smaller for arbiter. Is it safe to deploy it only on two nodes?
the host arbiter can be even just a Raspberry PI as far as I can tell. Adding Sahina.
Am I wrong?

Hello Jarek, As of today we cannot have gdeploy to work with different devices on different nodes for deploying HC. Currently device name has to be same on data and arbiter nodes. Hope this helps !! Thanks kasturi On Wed, Dec 20, 2017 at 2:29 PM, Jarek <jaru@jaru.eu.org> wrote:

It can be good idea: 2 physical nodes with local disks (raid6) as gluster bricks + 2 kvm vms with pcs and drbd for arbiter.
Just be sure to not run the kvm vms arbiters on the same real hosts or it may become a mess.
I'll test it.

Yes, I checked it but it seems I still need three nodes - 2 for storage and one smaller for arbiter. Is it safe to deploy it only on two nodes?
the host arbiter can be even just a Raspberry PI as far as I can tell. Adding Sahina.
Am I wrong?
