Hey everyone!
I have deployed gluster on 3 nodes with 4 SSDs each and 10Gb Ethernet connection.
The storage is configured with 3 gluster volumes, every volume has 12 bricks (4 bricks on every server, 1 per ssd in the server).
With the 'features.shard' off option my writing speed (using the 'dd' command) is approximately 250 Mbs and when the feature is on the writing speed is around 130mbs.
--------- gluster version 3.8.13 --------
Volume name: data
Number of bricks : 4 * 3 = 12
Bricks:
Brick1: server1:/brick/data1
Brick2: server1:/brick/data2
Brick3: server1:/brick/data3
Brick4: server1:/brick/data4
Brick5: server2:/brick/data1
.
.
.
Options reconfigure:
Performance.strict-o-direct: off
Cluster.nufa: off
Features.shard-block-size: 512MB
Features.shard: on
Cluster.server-quorum-type: server
Cluster.quorum-type: auto
Cluster.eager-lock: enable
Network.remote-dio: on
Performance.readdir-ahead: on
Any idea on how to improve my performance?
