Guys! I have followed the very same instruction that found in the James's website.
One of method his mentioned in that website, is create a file into /etc/glusterfs directory, named datastore.vol, for instance, with this content:
volume remote1
type protocol/client
option transport-type tcp
option remote-host server1
option remote-subvolume /data/storage
end-volume
volume remote2
type protocol/client
option transport-type tcp
option remote-host server2
option remote-subvolume /data/storage
end-volume
volume remote3
type protocol/client
option transport-type tcp
option remote-host server3
option remote-subvolume /data/storage
end-volume
volume replicate
type cluster/replicate
subvolumes remote1 remote2 remote3
end-volume
volume writebehind
type performance/write-behind
option window-size 1MB
subvolumes replicate
end-volume
volume cache
type performance/io-cache
option cache-size 512MB
subvolumes writebehind
end-volume
and then include this line into fstab:
/etc/glusterfs/datastore.vol [MOUNT] glusterfs rw,allow_other,default_permissions,max_read=131072 0 0 |

You can add a third server as an arbiter which does not store data in the bricks, but still uses some minimal space (to keep metadata for the files).HTH,DIegoOn Wed, Jan 23, 2019 at 3:06 PM Gilberto Nunes <gilberto.nunes32@xxxxxxxxx> wrote:_______________________________________________Hit there...I have set up two server as replica, like this:gluster vol create Vol01 server1:/data/storage server2:/data/storageThen I create a config file in client, like this:volume remote1type protocol/clientoption transport-type tcpoption remote-host server1option remote-subvolume /data/storageend-volumevolume remote2type protocol/clientoption transport-type tcpoption remote-host server2option remote-subvolume /data/storageend-volumevolume replicatetype cluster/replicatesubvolumes remote1 remote2end-volumevolume writebehindtype performance/write-behindoption window-size 1MBsubvolumes replicateend-volumevolume cachetype performance/io-cacheoption cache-size 512MBsubvolumes writebehindend-volumeAnd add this line in /etc/fstab/etc/glusterfs/datastore.vol /mnt glusterfs defaults,_netdev 0 0After mount /mnt, I can access the servers.
