[Gluster-users] GlausterFS guest machine I/O is too slow...

[Punit Dambiwal]

Hi,

I have the following setup :-

4* node in distributed replicated
replica =2
24*brick in each node....
i am using each brick as 256GB SSD...
I have 2*10Gb lan with bonding for storage purpose

As i am using SSD but still i am getting the very slow I/O  In my guest
VM.....

[root at centos7-2 ~]# dd if=/dev/zero of=/tmp/output bs=1M count=1k;rm -rf
/tmp/output
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 12.9764 s, 82.7 MB/s
[root at centos7-2 ~]#

If i run the same command on the host it's around 561MB/s...

[root at cpu04 10.10.0.6:_vol1]# dd if=/dev/zero
of=/rhev/data-center/mnt/glusterSD/10.10.0.6:_vol1/output bs=1M count=1k;rm
-rf /rhev/data-center/mnt/glusterSD/10.10.0.6:_vol1/output
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 1.91395 s, 561 MB/s
[root at cpu04 10.10.0.6:_vol1]#

Is there any way to optimize it for KVM virtulization....so i will get the
best use of the SSD...

Thanks,
Punit
