Hi, please see; https://docs.gluster.org/en/latest/Administrator-Guide/Managing-Volumes/
Gluster offers online expansion of the volume you can add bricks and/or nodes without taking mariadb offline if you want. just use the; gluster volume add-brick [vol] [bricks] (bricks must be added according your replication count, in your case 2) or use; gluster volume replace-brick [vol] [brick] to replace a single brick Best Olaf Op do 24 dec. 2020 om 23:35 schreef Bambang Sumitra < [email
