Re: [Gluster-users] Отн: Gluster performance issues - need advise
Dear Darrell, I found the issue and now I can reach the maximum of the network with a fuse client.Here is a short overview:1. I noticed that working with a new gluster volume is reaching my network speed - I was quite excited.2. Then I have destroyed my gluster volume and created a new one and started adding features from ovirt Once I have added features.shard on -> I hit the same performance from before. Increasing the shard size to 16MB didn't help at all. For my case where I have 2 Virtualization hosts with single data gluster volume - sharding is not neccessary, but for larger setups it will be a problem. As this looks to me as a bug - can someone tell me where I can report it ? Thanks to all who guided me in this journey of GlusterFS ! I have learned so much , as my prior knowledge was only in Ceph.

Гринуич+2, Darrell Budic <budic@onholyground.com> написа: Strahil- The fuse client is what it is, it’s limited by operating in user land and waiting for the gluster servers to acknowledge all the writes. I noted you're using ovirt, you should look into enabling the libgfapi engine setting to run your VMs with libgf natively. You can’t test directly from the host with that, but you can run your tests inside the VMs. I saw significant throughput and latency improvements that way. It’s still somewhat beta, so you’ll probably need to search the overt-users mailing list to find info on enabling it. Good luck!

I have added the following:server.event-threads: 4 client.event-threads: 4 performance.stat-prefetch: onperformance.strict-o-direct: off Results: no change 2. Allowed nfs and connected ovirt1 to the gluster volume:nfs.disable: off Results: Drastic improvement in performance as follows: [root@ovirt1 data]# dd if=/dev/zero of=largeio bs=1M count=5000 status=progress 5000+0 records in 5000+0 records out 5242880000 bytes (5.2 GB) copied, 53.0443 s, 98.8 MB/s So I would be happy if anyone guide me in order to fix the situation as the fuse client is the best way to use glusterfs, and it seems the glusterfs-server is not the guilty one.

Are you concerned the performance is 49MB/s with and without perf options? or are you expecting it to be 123MB/s as over the n/w you get that speed?
If it is the first problem, then you are actually having 'performance.write-behind on' in both options, and it is the only perf xlator which comes into action during the test you ran.
If it is the second, then please be informed that gluster does client side replication, which means, n/w would be split in half for write operations (like write(), creat() etc), so the number you are getting is almost the maximum with 1GbE.

Hello Community,
recently I have built a new lab based on oVirt and CentOS 7. During deployment I had some hicups, but now the engine is up and running - but gluster is causing me trouble.
Symptoms: Slow VM install from DVD, poor write performance. The latter has been tested via: dd if=/dev/zero of=/rhev/data-center/mnt/glusterSD/ovirt1.localdomain:_data bs=1M count=1000 status=progress
The reported speed is 60MB/s which is way too low for my setup.
My lab design: https://drive.google.com/file/d/1SiW21ASPXHRAEuE_jZ50R3FoO-NcnFqT/view?usp=s... Gluster version is 3.12.15
So far I have done:
1. Added 'server.allow-insecure on' (with 'option rpc-auth-allow-insecure on' in glusterd.vol) Volume info after that change:
Volume Name: data Type: Replicate Volume ID: 9b06a1e9-8102-4cd7-bc56-84960a1efaa2 Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: ovirt1.localdomain:/gluster_bricks/data/data Brick2: ovirt2.localdomain:/gluster_bricks/data/data Brick3: ovirt3.localdomain:/gluster_bricks/data/data (arbiter) Options Reconfigured: performance.client-io-threads: off nfs.disable: on transport.address-family: inet performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.low-prio-threads: 32 network.remote-dio: off cluster.eager-lock: enable cluster.quorum-type: auto cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off storage.owner-uid: 36 storage.owner-gid: 36 network.ping-timeout: 30 performance.strict-o-direct: on cluster.granular-entry-heal: enable server.allow-insecure: on
Seems no positive or negative effect so far.
2. Tested with tmpfs on all bricks -> ovirt1 mounted gluster volume -> max 60MB/s (bs=1M without 'oflag=direct')

This indicates to me that it's not a problem in Disk/LVM/FileSystem layout.
Most probably I haven't created the volume properly or some option/feature is disabled ?!? Network shows OK for a gigabit: [root@ovirt1 data]# dd if=/dev/zero status=progress | nc ovirt2 9999 3569227264 bytes (3.6 GB) copied, 29.001052 s, 123 MB/s^C 7180980+0 records in 7180979+0 records out 3676661248 bytes (3.7 GB) copied, 29.8739 s, 123 MB/s
I'm looking for any help... you can share your volume info also.
Thanks in advance.
