安装 glusterfs 3.3.0 配置replica...
需要使用两台服务器作gluster replication server端，同时把server端当client端
server1 10.10.10.10
server2 10.10.10.11
进入server1 root下
sudo -s
分别在两台服务器上添加
vim /etc/hosts
10.10.10.10 server1
10.10.10.11 server2
cat /etc/hosts
127.0.0.1 localhost
10.10.10.10 server1
10.10.10.11 server2
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
安装配置Gluster
http://download.gluster.org/pub/gluster/glusterfs/LATEST/Ubuntu/12.04/glusterfs_3.3.0-1_amd64.deb
apt-get install flex bison libssl-dev fuse fuse-utils libevent-dev libreadline6-dev
dpkg -i glusterfs_3.3.0-1_amd64.deb
update-rc.d glusterd defaults
/etc/init.d/glusterd start
安装完成后在server1运行如下命令：
glusterfs --version

mkdir /srv/filestore
mount -t glusterfs server2:/filestore /srv/filstore
然后运行mount 或df -h 查看是否挂载上了
mount
/dev/mapper/server3-root on / type ext4 (rw,errors=remount-ro)

server2:/filestore on /mnt/glusterfs type fuse.glusterfs (rw,allow_other,default_permissions,max_read=131072)
echo "server1:/filestore /srv/filestore glusterfs defaults,_netdev 0 0" >> /etc/fstab
重启服务器 shutdown -h now 系统启动时挂载server2:/filestore
cd /srv/filestore/
touch {1,2,3,4}
dd if=/dev/zero of=test01 bs=1M count=10
dd if=/dev/zero of=test02 bs=1M count=10
ls -l /srv/filestore

-rw-r--r-- 1 root root 0 Oct 8 11:30 2
-rw-r--r-- 1 root root 0 Oct 8 11:30 3

-rw-r--r-- 1 root root 10485760 Oct 8 11:31 test02
在server1 上查看/data/disk01下的内容
ls -l /data/disk01/
-rw-r--r-- 1 root root 0 Oct 8 11:30 1
-rw-r--r-- 1 root root 0 Oct 8 11:30 2

-rw-r--r-- 1 root root 10485760 Oct 8 11:31 test02
在server2上查看/data/disk01下的内容
ls -l /data/disk01
-rw-r--r-- 1 root root 0 Oct 8 11:30 1
-rw-r--r-- 1 root root 0 Oct 8 11:30 2
-rw-r--r-- 1 root root 0 Oct 8 11:30 3
-rw-r--r-- 1 root root 0 Oct 8 11:30 4

-rw-r--r-- 1 root root 10485760 Oct 8 11:31 test02
如果要配置distribute replication , 可以为replication 再添加两块磁盘。
gluster volume filestore add-brick server1:/data/disk02 server02:/data/disk02
gluster volume info filestore 就会变成
Volume Name: filestore
Type: Distribute Replicate
Status: Started
Number of Bricks: 2×2
Transport-type: tcp
Bricks:
Brick1: server1:/data/disk01
Brick2: server2:/data/disk01
Brick3: server1:/data/disk02
Brick4: server2:/data/disk02
数据需要fix-layout 和migrate-data 一下。
