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
