Did you observe something like that?</div><div><br></div><div>I have a 3 node Hyperconverged Cluster (ovirt + glusterfs with replica 3 arbiter1 volumes) with NFS Ganesha and since I have upgraded to v5 - the issues came up.</div><div>First it was 5.3 notorious experience and now with 5.5 - my sanlock is having problems and higher latency than it used to be. I have switched from NFS-Ganesha to pure FUSE , but the latency problems do not go away.</div><div><br></div><div>Of course , this is partially due to the consumer hardware, but as the hardware has not changed I was hoping that the performance will remain as is.</div><div><br></div><div>So, do you expect 5.5 to perform less than 3.12 ?</div><div><br></div><div>Some info:</div><div><span><div>Volume Name: engine</div><div>Type: Replicate</div><div>Volume ID: 30ca1cc2-f2f7-4749-9e2e-cee9d7099ded</div><div>Status: Started</div><div>Snapshot Count: 0</div><div>Number of Bricks: 1 x (2 + 1) = 3</div><div>Transport-type: tcp</div><div>Bricks:</div><div>Brick1: ovirt1:/gluster_bricks/engine/engine</div><div>Brick2: ovirt2:/gluster_bricks/engine/engine</div><div>Brick3: ovirt3:/gluster_bricks/engine/engine (arbiter)</div><div>Options Reconfigured:</div><div>performance.client-io-threads: off</div><div>nfs.disable: on</div><div>transport.address-family: inet</div><div>performance.quick-read: off</div><div>performance.read-ahead: off</div><div>performance.io-cache: off</div><div>performance.low-prio-threads: 32</div><div>network.remote-dio: off</div><div>cluster.eager-lock: enable</div><div>cluster.quorum-type: auto</div><div>cluster.server-quorum-type: server</div><div>cluster.data-self-heal-algorithm: full</div><div>cluster.locking-scheme: granular</div><div>cluster.shd-max-threads: 8</div><div>cluster.shd-wait-qlength: 10000</div><div>features.shard: on</div><div>user.cifs: off</div><div>storage.owner-uid: 36</div><div>storage.owner-gid: 36</div><div>network.ping-timeout: 30</div><div>performance.strict-o-direct: on</div><div>cluster.granular-entry-heal: enable</div><div>cluster.enable-shared-storage: enable</div></span><br></div><div>Network: 1 gbit/s</div><div><br></div><div>Filesystem:XFS</div><div><br></div><div>Best Regards,</div><div>Strahil Nikolov</div><div><br></div></div></body></html>
