2 安装
2.1 部署拓扑
3台存储服务器: 192.168.4.132、192.168.4.133、192.168.4.134
root@block2:/glusterfs# cat /etc/hosts
127.0.0.1 localhost
192.168.4.130 controller
192.168.4.131 network
192.168.4.132 compute
192.168.4.133 block1
192.168.4.134 block2
2.2 安装
在所有存储服务器上执行安装。
2.2.1 如果出现错误：
W: Failed to fetch http://ppa.launchpad.net/gluster/glusterfs-3.8/ubuntu/dists/trusty/main/binary-amd64/Packages Hash Sum mismatch
W: Failed to fetch http://ppa.launchpad.net/gluster/glusterfs-3.8/ubuntu/dists/trusty/main/binary-i386/Packages Hash Sum mismatch
W: Failed to fetch http://ppa.launchpad.net/gluster/glusterfs-3.8/ubuntu/dists/trusty/main/i18n/Translation-en Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old ones used instead.
是因为没有把这3个文件取到/var/lib/apt/lists目录下。正常情况下：
root@block1:~# ls /var/lib/apt/lists/ppa*
/var/lib/apt/lists/ppa.launchpad.net_gluster_glusterfs-3.8_ubuntu_dists_trusty_InRelease
/var/lib/apt/lists/ppa.launchpad.net_gluster_glusterfs-3.8_ubuntu_dists_trusty_main_binary-amd64_Packages
/var/lib/apt/lists/ppa.launchpad.net_gluster_glusterfs-3.8_ubuntu_dists_trusty_main_binary-i386_Packages
/var/lib/apt/lists/ppa.launchpad.net_gluster_glusterfs-3.8_ubuntu_dists_trusty_main_i18n_Translation-en
解决方法：
将/var/lib/apt/lists/partial/下的所有文件删除，但是这可以解决大部分问题，个别源不能解决，
注：经过长时间的实践，这个解决方法不是万能的。
2.2.2 安装glusterfs-server时，会安装glusterfs-client

3 集群关联
3.1创建GlusterFS集群
$ gluster peer probe SERVER SERVER表示存储服务器的hostname。
在服务器192.168.4.132上执行：
root@compute:~# gluster peer probe
Usage: peer probe <HOSTNAME>
root@compute:~# gluster peer probe block1
peer probe: success
root@compute:~# gluster peer probe block2
peer probe: success
注意：在构建GlusterFS集群时，需要在其中任意一台存储服务器上依次将其他存储服务器添加到集群中。
3.2 查看集群信息
指令：gluster peer status
root@compute:/etc/glusterfs# gluster peer status
Number of Peers: 2
Hostname: block1
Port: 24007
Uuid: ac468b50-3d66-4290-aa8d-cb01279e9bf2
State: Peer in Cluster (Connected)
Hostname: block2
Port: 24007
Uuid: 06288da0-1b18-42fb-a7b8-cd9ca24d5f26
State: Peer in Cluster (Connected)
root@block1:/etc/glusterfs# gluster peer status
Number of Peers: 2
Hostname: 192.168.4.132
Port: 24007
Uuid: 9fdd15f2-c7e1-44e1-9315-d62e1dcfb44d
State: Peer in Cluster (Connected)
Hostname: block2
Uuid: 06288da0-1b18-42fb-a7b8-cd9ca24d5f26
State: Peer in Cluster (Connected)
root@block1:/etc/glusterfs# gluster volume info
No volumes present
Connected,说明集群节点添加成功，但其中compute是以192.168.4.132这个ip加入集群的，如果需要换成hostname，登陆集群中的集群中的另一个节点，执行：
root@block1:~# gluster peer detach 192.168.4.132
peer detach: success
root@block1:~#
root@block1:~# gluster peer status
Number of Peers: 1
Hostname: block2
Uuid: 06288da0-1b18-42fb-a7b8-cd9ca24d5f26

State: Peer in Cluster (Connected)
4 Volume卷操作
基本卷：
(1) distribute volume：分布式卷
文件通过hash算法分布到所有brick server上，这种卷是glusterfs的基础和最大特点。优点是容量大，缺点是没冗余。
(2) stripe volume：条带卷
类似RAID0，文件分成数据块以Round Robin方式分布到brick server上，并发粒度是数据块，支持超大文件，大文件性能高；优点是分布式读写，性能整体较好。缺点是没冗余，分片随机读写可能会导致硬盘IOPS饱和。
(3) replica volume：复制卷
文件同步复制到多个brick上，文件级RAID 1，具有容错能力，写性能下降，读性能提升。缺点是磁盘利用率低。
复合卷：
(4) distribute stripe volume：分布式条带卷
brickserver数量是条带数的倍数，兼具distribute和stripe卷的特点；
(5) distribute replica volume：分布式复制卷
brickserver数量是镜像数的倍数，兼具distribute和replica卷的特点,可以在2个或多个节点之间复制数据。
(6) stripe replica volume：条带复制卷
类似RAID 10
同时具有条带卷和复制卷的特点
(7) distribute stripe replicavolume：分布式条带复制卷
三种基本卷的复合卷
通常用于类Map Reduce应用
(8) 冗余卷（Dispersed volume）
近似于raid5，文件分片存储在各个硬盘上，但有部分硬盘用于冗余用途，数量可以指定。比如一共10块硬盘，2块盘用于冗余，那么就可以承受同时损坏两块硬盘，总容量是8块盘。
优点是在冗余和性能之间取得平衡
4.1．创建volume
a. 单磁盘，调试环境推荐
sudo gluster volume create vol_name 172.17.0.2:/d/disk0
b. 多磁盘，无raid，试验、测试环境推荐。
sudo gluster volume create vol_name 172.17.0.2:/d/disk0 172.17.0.3:/d/disk0 172.17.0.4:/d/disk0 172.17.0.5:/d/disk0
c. 多磁盘，有raid1。线上高并发环境推荐。
Usage: volume create <NEW-VOLNAME> [stripe <COUNT>] [replica <COUNT> [arbiter <COUNT>]] [disperse [<COUNT>]] [disperse-data <COUNT>] [redundancy <COUNT>] [transport <tcp|rdma|tcp,rdma>] <NEW-BRICK>?<vg_name>... [force]
注意：以上命令中，磁盘数量必须为复制份数的整数倍。
实验命令是在根目录下创建目录/glusterfs，要在所有的3台服务器上都创建这个目录，否则会出错。
root@compute:~# gluster volume create zhai-volume replica 2 192.168.4.132:/glusterfs/brick1 block1:/glusterfs/brick1 block2:/glusterfs/brick1
number of bricks is not a multiple of replica count
Usage: volume create <NEW-VOLNAME> [stripe <COUNT>] [replica <COUNT> [arbiter <COUNT>]] [disperse [<COUNT>]] [disperse-data <COUNT>] [redundancy <COUNT>] [transport <tcp|rdma|tcp,rdma>] <NEW-BRICK>?<vg_name>... [force]
root@compute:~#
root@compute:~# gluster volume create zhai-volume replica 2 compute:/glusterfs/brick1 compute:/glusterfs/brick2 block1:/glusterfs/brick1 block1:/glusterfs/brick2 block2:/glusterfs/brick1 block2:/glusterfs/brick2
volume create: zhai-volume: failed: The brick compute:/glusterfs/brick1 is being created in the root partition. It is recommended that you don't use the system's root partition for storage backend. Or use 'force' at the end of the command if you want to override this behavior.

Volume ID: 779a7440-e127-43c6-a13f-7420ab8baec8
Status: Created
Snapshot Count: 0
Number of Bricks: 3 x 2 = 6
Transport-type: tcp
Bricks:
Brick1: compute:/glusterfs/brick1
Brick2: compute:/glusterfs/brick2
Brick3: block1:/glusterfs/brick1
Brick4: block1:/glusterfs/brick2
Brick5: block2:/glusterfs/brick1
Brick6: block2:/glusterfs/brick2
Options Reconfigured:
transport.address-family: inet
Note: The number of bricks should be a multiple of the replica count for a distributed replicated volume. Also, the order in which bricks are specified has a great effect on data protection. Each replica_count consecutive bricks in the list you give will form a replica set, with all replica sets combined into a volume-wide distribute set.
volume创建成功后，会在每台服务器的/glusterfs目录下生成brick1和brick2目录。

4.3．挂载volume
4.3.1 在3台服务器中任一服务器上挂载都可以。
For this step, we will use one of the servers to mount the volume. Typically, you would do this from an external machine, known as a "client". Since using this method would require additional packages to be installed on the client machine, we willuse one of the servers as a simple place to test first, as if it were that "client".
# 挂载任一节点即可(推荐)
root@compute:~# mount -t glusterfs 192.168.4.132:/zhai-volume /mnt
root@compute:~# df -h

192.168.4.132:/zhai-volume 2.7T 6.0G 2.6T 1% /mnt
4.3.2 在3台服务器之外的服务器上挂载
需要安装glusterfs-client包
否则，出错：
root@network:~# mount -t glusterfs 192.168.4.132:/zhai-volume /mnt
mount: unknown filesystem type 'glusterfs'
安装
sudo apt-get install glusterfs-client
安装后，执行挂载
[plain] view plain copy
# mount -t glusterfs 10.10.30.4:/zhai-volume /mnt
Mount failed. Please check the log file for more details.
原因：没有在/etc/hosts中添加glusterfs集群中各个服务器的信息
4.3.3 开机挂载
# 若需要开机自动挂载，请更新/etc/fstab
4.4．使用GlusterFS
a. 挂载了GlusterFS的某个卷后，就可以将其当做本地文件访问，代码中只需使用原生的文件api即可。这种方式使用不一定需要root权限，只要拥有对应目录或文件的权限即可。
b. 直接API方式，这种方式需要root权限才能使用，并且java、python、ruby的api包装目前都不够完整，一般情况不推荐使用。
到
测试1：
到/mnt目录下创建文件：
root@compute:/mnt# uname -a >info
root@compute:/mnt# ls
info
root@compute:/mnt# cat info
Linux compute 4.4.0-31-generic #50~14.04.1-Ubuntu SMP Wed Jul 13 01:07:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
在3台服务器上查看，在block2服务器上生成文件，在block1和compute结点上没有生成文件：
root@block2:~# ls /glusterfs/brick1/
info
root@block2:~# ls /glusterfs/brick2
info
root@block2:~# cat /glusterfs/brick1/info
Linux compute 4.4.0-31-generic #50~14.04.1-Ubuntu SMP Wed Jul 13 01:07:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
测试2：
mount -t glusterfs server1:/gv0 /mnt
for i in `seq -w 1 100`; do cp -rp /var/log/messages /mnt/copy-test-$i; done
First, check the mount point:
ls -lA /mnt | wc -l
You should see 100 files returned. Next, check the GlusterFS mount points on each server:
ls -lA /data/brick1/gv0
You should see 100 files on each server using the method we listed here. Without replication, in a distribute only volume (not detailed here), you should see about 50 files on each one.
4.5．卸载volume
卸载与挂载操作是一对。虽然没有卸载也可以停止volume，但是这样做是会出问题，如果集群较大，可能导致后面volume启动失败。
sudo umount /mnt
4.6．停止volume
停止与启动操作是一对。停止前最好先卸载所有客户端。
sudo gluster volume stop vol_name
4.7．删除volume
删除与创建操作是一对。删除前需要先停止volume。在生产上一般不会删除volume
sudo gluster volume delete vol_name
5 使用独立存储
使用独立/dev/sdb
5.1 分区
fdisk /dev/sdb //创建分区，输入,n,p,w，创建新主分区并写入分区表
5.2 Format and mount the bricks
(on both nodes): Note: These examples are going to assume the brick is going to reside on /dev/sdb1.
mkfs.xfs -i size=512 /dev/sdb1
mkdir -p /data/brick1
echo '/dev/sdb1 /data/brick1 xfs defaults 1 2' >> /etc/fstab
mount -a && mount
You should now see sdb1 mounted at /data/brick1
root@block1:~# mkfs.xfs -i size=512 /dev/sdb1
root@compute:~# echo '/dev/sdb1 /glusterfs xfs defaults 1 2' >> /etc/fstab

mount之后再安装glusterfs
5.3 其它命令
#apt-get install xfsprogs //安装xfs文件系统（如果没有的话），更安全可靠
#lshw -short //查看硬件信息，主要是查看硬盘信息，以决定哪块硬盘作为gluster来使用
或使用lsblk来查看块设备
