[Gluster-users] Recovery when 2 of 3 servers goes down!

[Gilberto Nunes]

How there

I have 3 servers with gluster 7 installed and setting up with replica 3 and
arbiter 1.
Here's the commands I used:
- First create a simple volume with one server:
gluster volume create VMS proxmox01:/DATA/vms
- Then add the second one
gluster peer probe proxmox02
gluster volume add-brick VMS replica 2 proxmox02:/DATA/vms
- And finally and the third:
gluster peer probe proxmox03
gluster volume add-brick VMS replica 3 arbiter 1 proxmox03:/DATA/vms

But then I decide to test the environment and bring proxmox02 and proxmox03
down and get Transport endpoint is not connected after a few seconds.
Is there a way to keep one server up if 2 goes down?
