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/brick/thedude force 3. gluster volume add-brick thedude replica 3 arbiter 1 <IP:brick path of the new arbiter brick>Would it be good to have this small sequence of steps noted down somewhere other than a mailing list archive? I imagine this is going to be sought out by a few more users choosing this course.
