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 should...

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.

Hi folks, I'm troubled moving an arbiter brick to another server because of I/O load issues.

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 mention...

Is that possible ? How ? 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. 2. gluster volume remove-brick thedude replica 2 ngluster-3.network.hoggins.fr:/export/...

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? -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
