[ovirt-users] Expand existing gluster storage in ovirt 4.2/4.3

Hello, I have a 3 node ovirt 4.3 cluster that I've setup and using gluster (Hyperconverged setup) I need to increase the amount of storage and compute so I added a 4th host (server4.example.com) if it is possible to expand the amount of bricks (storage) in the "data" volume? I did some research and from that research the following caught my eye: old post "https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-62dd6614194e" So the question is, if taking that approach feasible? , is it even possible an oVirt point of view? --------------------------- My gluster volume: --------------------------- Volume Name: data Type: Replicate Volume ID: 003ffea0-b441-43cb-a38f-ccdf6ffb77f8 Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: server1.example1.com:/gluster_bricks/data/data Brick2: server2.example.com:/gluster_bricks/data/data Brick3: server3.example.com:/gluster_bricks/data/data (arbiter) Options Reconfigured: cluster.granular-entry-heal: enable performance.strict-o-direct: on network.ping-timeout: 30 storage.owner-gid: 36 storage.owner-uid: 36 cluster.choose-local: off user.cifs: off features.shard: on cluster.shd-wait-qlength: 10000 cluster.shd-max-threads: 8 cluster.locking-scheme: granular cluster.data-self-heal-algorithm: full cluster.server-quorum-type: server cluster.quorum-type: auto cluster.eager-lock: enable network.remote-dio: enable performance.low-prio-threads: 32 performance.io-cache: off performance.read-ahead: off performance.quick-read: off transport.address-family: inet nfs.disable: on performance.client-io-threads: off Thanks.
