bonding question

[Demeter Tibor <tdemeter@xxxxxxxxxx>]

Hi,

I made short tests with glusterfs and bonding, but I have performance issues.

Environment:

- bonding mode=4 (with switch support) or mode=6 

- centos7

- vlans

- two servers with 4 nic/node, one nic on the internet (this is the default route) and 3 nic as bonded interface

- MTU 9000 on all interface (bondings, vlans, eths, etc), MTU 9216 on the switch ports

- each host vlan-s can ping each host on the vlan subnets and on the non vlan subnets.

- the volume uses the bonded vlans as bricks

[root@node1 lock]# gluster vol info

Volume Name: meta
Type: Replicate
Volume ID: f4d026e7-3edd-442f-9207-f0a849acebf5
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: gs00.itsmart.cloud:/gluster/meta0
Brick2: gs01.itsmart.cloud:/gluster/meta1

I did this test:

[root@node0 lock]# dd if=/dev/zero of=/mnt/lock/disk bs=1M count=1000 conv=fdatasync
1000+0 records in
1000+0 records out
1048576000 bytes (1,0 GB) copied, 10,3035 s, 102 MB/s

I compared with local hdd speed tests:

[root@node0 lock]# dd if=/dev/zero of=/home/disk bs=1M count=1000 conv=fdatasync
1000+0 records in
1000+0 records out
1048576000 bytes (1,0 GB) copied, 3,04411 s, 344 MB/s

Ok, I mean this is a network based solution, but I think the 100MB/sec is possible with one nic too.

I just wondering, maybe my bonding isn't working fine. 

What do you think, is it ok? 

The port utilization is minimal, there are two bigger traffic on two ports only.

Thanks in advance.

Tibor
