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.

Hello,
I have two servers with replica 2 setup, with total of 380GB of disk space ( gluster volume create datastore replica 2 transport tcp server1:/datastore server2:/datastore).
I'd need to add more capacity to the servers, I know I need to add 2 more servers to the configuration, however do they need to be with the same disk size ? Meaning, if I add a 2 VMs with 20GB bricks, that would expand the volume by 20GB ?
Second part is mounting, I'm curious if anything would change in the current fstab entry:
server1:/datastore /mnt/datastore glusterfs default,_netdev,backupvolfile-server=server2 0 0
Gluster would properly utilize all 4 servers in this case, or fstab entry needs to be modified ?
Thank you!
