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!

Dear Amar, Community,

it seems the issue is in the fuse client itself.

Here is the latest update:
1. I have added the following:
server.event-threads: 4
client.event-threads: 4
performance.stat-prefetch: on
performance.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.

Thanks in advance for your guidance.I have learned so much.

Best Regards,
Strahil Nikolov

Тема: Re: [Gluster-users] Gluster performance issues - need advise

Dear Amar,

Thanks for your email.

Actually my concerns were on both topics.
Would you recommend any perf options that will be suitable ?

After mentioning the network usage, I just checked it and it seems duringthe test session, ovirt1 (both client and host) is using no more than 455Mbit/s which is half the network bandwidth.

I'm still in the middle of nowhere, so any ideas are welcome.

Best Regards,
Strahil Nikolov

I didn't understand the issue properly. Mostly I missed something.

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.

Amar

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=sharing
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

I'm looking for any help... you can share your volume info also.

Thanks in advance.
