<div dir="ltr">Hi folks,<br><br> I have been experimenting with oVirt cluster based on glusterfs for the past few days. (first-timer). The cluster is up and running and it consists of 4 nodes and has 4 replicas. When I try to deploy Windows Server VM I encounter the following issue: The disk of the VM has ok reading speed ( close to bare metal) but the writing speed is very slow. ( about 10 times slower than it is supposed to be). Can anyone give me any suggestion, please? Thanks in advance! Here are the settings of the glusterfs volume:<br><br>Volume Name: bottle-volume<br>Type: Replicate<br>Volume ID: 869b8d1e-1266-4820-8dcd-4fea92346b90<br>Status: Started<br>Snapshot Count: 0<br>Number of Bricks: 1 x 4 = 4<br>Transport-type: tcp<br>Bricks:<br>Brick1: cnode01.bottleship.local:/gluster_bricks/brick-cnode01/brick-cnode01<br>Brick2: cnode02.bottleship.local:/gluster_bricks/brick-cnode02/brick-cnode02<br>Brick3: cnode03.bottleship.local:/gluster_bricks/brick-cnode03/brick-cnode03<br>Brick4: cnode04.bottleship.local:/gluster_bricks/brick-cnode04/brick-cnode04<br>Options Reconfigured:<br>network.ping-timeout: 30<br>cluster.granular-entry-heal: enable<br>performance.strict-o-direct: on<br>storage.owner-gid: 36<br>storage.owner-uid: 36<br>server.event-threads: 4<br>client.event-threads: 4<br>cluster.choose-local: off<br>features.shard: on<br>cluster.shd-wait-qlength: 10000<br>cluster.shd-max-threads: 8<br>cluster.locking-scheme: granular<br>cluster.data-self-heal-algorithm: full<br>cluster.server-quorum-type: server<br>cluster.quorum-type: auto<br>cluster.eager-lock: enable<br>network.remote-dio: off<br>performance.low-prio-threads: 32<br>performance.io-cache: off<br>performance.read-ahead: off<br>performance.quick-read: off<br>auth.allow: *<br>user.cifs: off<br>transport.address-family: inet<br>nfs.disable: on<br>performance.client-io-threads: off<br>server.allow-insecure: on<br><br>Please let me know if you need any more configuration info or hardware specs.<br><br>best,<br><br>Lyubo<br><br><div><br></div><br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div style="font-size:12.8px"><div style="font-size:12.8px"></div><div><br></div></div><div><br></div></div></div></div></div></div></div>
