Syntax for creating arbiter volumes in gluster 4.0
Hi,
The existing syntax in the gluster CLI for creating arbiter volumes is
`gluster volume create <volname> replica 3 arbiter 1 <list of bricks>` .
It means (or at least intended to mean) that out of the 3 bricks, 1
brick is the arbiter.
There has been some feedback while implementing arbiter support in
glusterd2 for glusterfs-4.0 that we shou...

arbiter node on client?
is possible to add an arbiter node on the client?
Let's assume a gluster storage made with 2 storage server. This is prone to
split-brains.
An arbiter node can be added, but can I put the arbiter on one of the
client ?
Can I use multiple arbiter for the same volume ? In example, one arbiter on
each client.

I've been running in that configuration for a couple months now with no
problems. I have 6 data + 3 arbiter bricks hosting VM disk images and
all three of my arbiter bricks are on one of the kvm hosts.

Arbiter node as VM
Hello,
I have a replica 2 GlusterFS 3.8.11 cluster on 2 Debian 8 physical servers using ZFS as filesystem. Now in order to avoid a split-brain situation I would like to add a third node as arbiter.
Regarding the arbiter node I have a few questions:
- can the arbiter node be a virtual machine? (I am planning to use Xen as hypervisor)
- can I use ext4 as file system on my arbiter? or does it need to be ZFS as the two other nodes?
- or should I use here XFS with LVM this provisioning as menti...

Yes, you would need to reduce it to replica 2 and then convert it to
arbiter.
1. Ensure there are no pending heals, i.e. heal info shows zero entries.

How large the Arbiter node?
Hi,
I see gluster now recommends the use of an arbiter brick in "replica 2" situations.
How large should this brick be? I understand only metadata is to be stored.
Let's say total storage usage will be 5TB of mixed size files. How large should such a brick be?
