Hi! Until now, I use Gluster in a 2-server setup (volumes created with replica 2). Upgrading the hardware, it would be helpful to extend to volume to replica 3 to integrate the new machine and adding the respective brick and to reduce it later back to 2 and removing the respective brick when the old machine is cancelled and not used anymore. But it seems that this requires to delete and recreate the volumes, as I did not find a way to increase/decrease the replica value. Any hints? Regards,
