[Gluster-users] Convert replica 2 to replica 2+1 arbiter
Hi! I am using GlusterFS on CentOS7 with glusterfs-3.8.15 RPM version. I currently have a replica 2 running and I would like to get rid of the split-brain problem before it occurs. This is one of the possible solutions. Is it possible to and an arbiter to this volume? I have read in a thread from 2016 that this feature is planned for version 3.8. Is the feature available? If so, could you give me an example of how to do it? Kind regards, Mitja
gluster volume add-brick volname replica 3 arbiter 1 brickhost:brickpath/to/new/arbitervol Yes. The replica 3 looks odd. Somewhere in 3.12 (?) or not until v4 a change in command will happen so it won't count the arbiter as a replica.

I must ask again, just to be sure. Is what you are proposing definitely supported in v3.8?
