Thanks, that sounds interesting. From what I understand, arbiter setups only support multiple-of-2 data bricks, but maybe it's possible to replace the arbiter with a data brick, then replace the old data brick with an arbiter again.

I'm not sure if you can increase (and later decrease) the replica count without stopping the volume.Have you checked that as an option ?Best Regards,Strahil Nikolov

________Hi,I am looking to replace a brick in a replicated volume with arbiter (2+1 bricks).Judging from this page: https://docs.gluster.org/en/latest/Administrator%20Guide/Managing%20Volumes/#replace-brickit seems that the procedure is: simulate a brick failure, then add a replacement brick.Is that the only way to do it? Isn't there a way to migrate the data on the fly without running on reduced redundancy during the migration, like pvmove exists for LVM?Thanks,Stefan
