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@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@centos7-2 ~]#
If i run the same command on the host it's around 561MB/s...
[root@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@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
