#GlusterFS 2 node:

#/etc/hosts: 2.2.2.240 gfs01 2.2.2.241 gfs02

#Installation:

apt-get install software-properties-common add-apt-repository ppa:gluster/glusterfs-4.1 apt-get update apt-get install glusterfs-server service glusterd start service glusterd status

#systemctl | grep gluster sudo systemctl enable glusterd.service sudo service glusterd.service start

#Testing on 2 node:

gfs01: gluster peer probe gfs02 gluster peer status gfs02: gluster peer probe gfs01 gluster peer status

#GFS01: Creating new VOLUME. Volumename = "volume1"

#gluster volume create volume1 replica 2 transport tcp gfs01:/opt/.gfserver gfs02:/opt/.gfserver force

gluster volume start volume1 gluster volume info gluster volume profile volume1 info gluster volume profile volume1 start gluster volume profile volume1 info gluster volume status

#TEST GFS01 + GFS02:

gluster pool list

gluster peer status

#If you want to delete current volume:

gluster volume stop volume1 gluster volume delete volume1 #service glusterd restart

#Cài đặt GLUSTER thành công. Tiến hành MOUNT ổ đĩa để hệ điều hành tự nhận mỗi khi reboot:

#DC1: #mkdir -p /opt/gfs #mount -t glusterfs gfs01:/volume1 /opt/gfs #echo "gfs01:/volume1 /opt/gfs glusterfs defaults 0 0" >> /etc/fstab

#DC2: #mkdir -p /opt/gfs #mount -t glusterfs gfs02:/volume1 /opt/gfs #echo "gfs02:/volume1 /opt/gfs glusterfs defaults 0 0" >> /etc/fstab

#PERFORMANCE TEST:

apt-get install iozone3 IOZONE=/opt/gfs/iozone mkdir -p $IOZONE cd $IOZONE echo "iozone -w -c -e -i 0 -+n -r 64k -s 1024m -t 8 -F f{0,1,2,3,4,5,6,7,8}.ioz"  > network.performance.load.test.sh chmod +x network.performance.load.test.sh ./network.performance.load.test.sh #
