Hi
I'm using Glusterfs-3.2.3 on CentOS 5.5 x86 .
In my environment, I have four node ,
and each server has 12 TB of disk size.
VOLUME A
Gluster 101 MASTER RAID1+0 12TB
Gluster 102 SLAVE RAID1+0 12TB
VOLUME B
Gluster 103 MASTER RAID1+0 12TB
Gluster 104 SLAVE RAID1+0 12TB
I have about 500 read requests per second , and the disk IO
is always very high . Is there any ideas to decrease disk IO ?
or is this the limit for Gluster ?
ex ) Disk utile os wlwayd aroude 90% , like this .
# iostat -xm 2
sdb 254.00 0.00 164.00 0.00 3.73 0.00 46.56
1.56 9.50 5.02 82.30
sdb1 254.00 0.00 164.00 0.00 3.73 0.00 46.56
1.56 9.50 5.02 82.30
