GlusterFs卷的简单操作

小咪咪 2021-10-23 14:48 299阅读 0赞

一、创建卷

gluster volume create

例子：gluster volume create gv0 replica 2 [server1:/data/brick1/gv0][server1_data_brick1_gv0] [server2:/data/brick1/gv0][server2_data_brick1_gv0]

报错

发现报错了，这是因为我们创建的brick在系统盘，这个在gluster的默认情况下是不允许的，生产环境下也尽可能的与系统盘分开，如果必须这样请使用force

gluster volume create gv0 replica 2 [server1:/data/brick1/gv0][server1_data_brick1_gv0] [server2:/data/brick1/gv0][server2_data_brick1_gv0] force

二、启动卷

gluster volume start

例子：gluster volume start  gv0

三、停止卷

gluster volume stop

例子:gluster volume stop gv0

四、 删除卷

gluster volume delete

例子：gluster volume delete  gv0

五、添加节点

gluster peer probe

例子：gluster peer probe server3

六、删除节点

gluster peer detach (移除节点，需要提前将该节点上的brick移除)

例子：gluster peer detach server3

七、查看卷

gluster volume list              /\*列出集群中的所有卷\*/

gluster volume info \[all\]      /\*查看集群中的卷信息\*/  
gluster volume status \[all\]  /\*查看集群中的卷状态\*/

八、 更改卷类型

1.需要先卸载挂载的目录

umount ／mnt

2.停止卷

3.更改卷的类型

语法：gluster volume set test-volume config.transport tcp,rdma OR tcp OR rdma

例子：

九、重新均衡卷

语法：gluster volume rebalance <VOLNAME> fix-layout start

例子：gluster volume rebalance test-volume fix-layout start

十、收缩卷

1.开始收缩

gluster volume  remove-brick  gv0 [server3:/data/brick1/gv0][server3_data_brick1_gv0] [server4:/data/brick1/gv0][server4_data_brick1_gv0] start

![image2017-10-31_2018_3A32_3A59.png_version_1_modificationDate_1509446136000_api_v2][]

2.查看迁移状态

gluster volume  remove-brick  gv0 [server3:/data/brick1/gv0][server3_data_brick1_gv0] [server4:/data/brick1/gv0][server4_data_brick1_gv0] status

![image2017-10-31_2018_3A33_3A38.png_version_1_modificationDate_1509446136000_api_v2][]

3.迁移完成提交

gluster volume  remove-brick  gv0 [server3:/data/brick1/gv0][server3_data_brick1_gv0] [server4:/data/brick1/gv0][server4_data_brick1_gv0] commit

![image2017-10-31_2018_3A34_3A8.png_version_1_modificationDate_1509446136000_api_v2][]

九.GlusterFS的配额

GlusterFS目录限额，允许你根据目录或卷配置限制磁盘空间的使用量

1.开启限额

`gluster volume ``quota` `VolumeName ``enable`

2.关闭限额

`gluster volume ``quota` `VolumeName disable`

3.设置或替换磁盘限制

3.1.根据卷限制

`gluster volume ` `quota`  `VolumeName limit-usage / size`

例子： `gluster volume ` `quota`  `gv0 limit-usage / 10GB`

3.2.根据目录限制

`gluster volume ` `quota`  `VolumeName limit-usage DirectoryPath LimitSize`
