[ovirt-users] Re: Gluster volume slower then raid1 zpool speed

I would love to see something similar to your performance numbers WK. Here is my gluster volume options and info: [root@ovirtn1 ~]# gluster v info vmstore Volume Name: vmstore Type: Replicate Volume ID: stuff Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: ovirtn1.5ervers.lan:/gluster_bricks/vmstore/vmstore Brick2: ovirtn2.5ervers.lan:/gluster_bricks/vmstore/vmstore Brick3: ovirtn3.5ervers.lan:/gluster_bricks/vmstore/vmstore (arbiter) Options Reconfigured: cluster.granular-entry-heal: enable performance.strict-o-direct: on network.ping-timeout: 30 storage.owner-gid: 36 storage.owner-uid: 36 server.event-threads: 4 client.event-threads: 4 cluster.choose-local: off user.cifs: off features.shard: on cluster.shd-wait-qlength: 10000 cluster.shd-max-threads: 8 cluster.locking-scheme: granular cluster.data-self-heal-algorithm: full cluster.server-quorum-type: server cluster.quorum-type: auto cluster.eager-lock: enable network.remote-dio: enable performance.low-prio-threads: 32 performance.io-cache: off performance.read-ahead: off performance.quick-read: off transport.address-family: inet storage.fips-mode-rchecksum: on nfs.disable: on performance.client-io-threads: on Does it look like sharding is on Strahil Nikolov? Running "gluster volume set vmstore group virt" had no effect. I don't know why I ended up using dsync flag. For real work test, I have crystal disk mark on windows VM, this is the results: https://gofile.io/d/7nOeEL
