Hello,
in replicated setup, all bricks have all data. So you need to grow all
bricks, or do a distributed + replicated volume
I would stay with 2 bricks and extend current volume or add another volume
to the current brick
No need to change fstab. It will try first server1 and server2 as a backup
if first is offline. Then gluster client get all nodes from the one it's
connected too.
So even if you have 50 bricks, no change in fstab.
Cordialement,
