<br>
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).<br>
<br>
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 ?<br>
<br>
Second part is mounting, I'm curious if anything would change in the current fstab entry:<br>
<br>
server1:/datastore /mnt/datastore glusterfs default,_netdev,backupvolfile-server=server2 0 0<br>
<br>
Gluster would properly utilize all 4 servers in this case, or fstab entry needs to be modified ?<br>
<br>
Thank you!<br>
