一、安装glusterfs
1、什么是glusterfs
Glusterfs是一个开源分布式文件系统，具有强大的横向扩展能力，可支持数PB存储容量和数千客户端，通过网络互联成一个并行的网络文件系统。具有可扩展性、高性能、高可用性等特点
2、安装glusterfs
所有节点
yum install centos-release-gluster -y yum install install glusterfs-server -y systemctl start glusterd.service systemctl enable glusterd.service mkdir -p /gfs/test1 mkdir -p /gfs/test2
二、添加存储资源池
master节点
[root@master ~]# gluster pool list UUID Hostname State e23fd83e-ed78-424d-a20c-c1cec983973e localhost Connected [root@master ~]# gluster peer probe node1 peer probe: failed: Probe returned with Transport endpoint is not connected [root@master ~]# gluster peer probe 192.168.118.19 peer probe: success. [root@master ~]# gluster peer probe 192.168.118.20 peer probe: success. [root@master ~]# gluster pool list UUID Hostname State 50dddc1a-eb2b-45ee-b063-be40a7bf8ee1 192.168.118.19 Connected db13d4ce-c9ac-4628-824c-72a67de4aa99 192.168.118.20 Connected e23fd83e-ed78-424d-a20c-c1cec983973e localhost Connected
三、glusterfs卷管理
创建分布式复制卷
root@master ~]# gluster volume create luoahong replica 2 192.168.118.18:/gfs/test1 192.168.118.18:/gfs/test2 192.168.118.19:/gfs/test1 192.168.118.19:/gfs/test2 force volume create: luoahong: success: please start the volume to access data
启动卷
[root@master ~]# gluster volume start luoahong volume start: luoahong: success
查看卷
[root@master ~]# gluster volume info luoahong Volume Name: luoahong Type: Distributed-Replicate Volume ID: 010f95a9-0ba6-4db2-96e8-3a8ed9e73c74 Status: Started Snapshot Count: 0 Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: 192.168.118.18:/gfs/test1 Brick2: 192.168.118.18:/gfs/test2 Brick3: 192.168.118.19:/gfs/test1 Brick4: 192.168.118.19:/gfs/test2 Options Reconfigured: transport.address-family: inet storage.fips-mode-rchecksum: on nfs.disable: on performance.client-io-threads: off
挂载卷
[root@master ~]# mount -t glusterfs 192.168.118.18:/luoahong /mnt
四、分布式复制卷扩容
分布式复制卷讲解
分布式复制卷扩容
扩容前查看容量：
[root@master ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/vda3 96G 9.3G 86G 10% / ...... 192.168.118.18:/luoahong 96G 7.1G 88G 8% /mnt
扩容命令：
[root@master ~]# gluster volume add-brick luoahong 192.168.118.20:/gfs/test1 192.168.118.20:/gfs/test2 force volume add-brick: success
扩容后查看容量:
[root@master ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/vda3 96G 9.3G 86G 10% / ...... 192.168.118.18:/luoahong 143G 8.9G 134G 7% /mnt
