基本操作
集群节点
扩展集群
1,必须做hosts域名解析
其实通过IP地址也能做集群,但是不建议这种方式.
192.168.1.210 glusterfs042, 添加节点到集群中,在当前所有集群节点中都需要执行
gluster peer probe glusterfs043,查看对等状态
gluster peer status查看集群节点信息
gluster pool list删除节点
从集群中删除节点
gluster peer detach glusterfs04卷
创建卷
distribute volume分布式卷(默认)
命令:
> gluster volume create NEW-VOLNAME [transport [tcp | rdma | tcp,rdma]] NEW-BRICK...示例:
> gluster volume create test-volume transport tcp glutserfs01:/guiji/pv1 gluster02:/guiji/pv1
Creation of test-volume has been successful
Please start the volume to access dataStriped Glusterfs Volume 条带卷
命令:
> gluster volume create NEW-VOLNAME [stripe COUNT] [transport [tcp | dma | tcp,rdma]] NEW-BRICK...示例:
> gluster volume create test-volume stripe 2 transport tcp glutserfs01:/guiji/pv1 gluster02:/guiji/pv1
Creation of test-volume has been successful
Please start the volume to access dataReplicated Glusterfs Volume 复制卷(最少两个节点)
命令:
> gluster volume create NEW-VOLNAME [replica COUNT] [transport [tcp | rdma | tcp,rdma]] NEW-BRICK...示例:
> gluster volume create test-volume replica 2 glutserfs01:/guiji/pv1 gluster02:/guiji/pv1
Creation of test-volume has been successful
Please start the volume to access dataDistributed Replicated Glusterfs Volume 分布式复制卷
命令:
> gluster volume create NEW-VOLNAME [replica COUNT] [transport [tcp | rdma | tcp，rdma]] NEW-BRICK ......示例:
两个节点组成分布式,镜像3份
> gluster volume create test-volume replica 3 transport tcp glutserfs01:/guiji/pv1 gluster02:/guiji/pv1 glutserfs03:/guiji/pv1 gluster04:/guiji/pv1 glutserfs05:/guiji/pv1 glusterfs06:/guiji/pv1
Creation of test-volume has been successful
Please start the volume to access dataglusterfs01和glusterfs02 组成分布式
glusterfs03和glusterfs04 组成分布式
glusterfs05和glusterfs06 组成分布式
然后在组成镜像
三个节点分布式镜像2份
> gluster volume create test-volume replica 2 transport tcp glutserfs01:/guiji/pv1 gluster02:/guiji/pv1 glutserfs03:/guiji/pv1 gluster04:/guiji/pv1 glutserfs05:/guiji/pv1 glusterfs06:/guiji/pv1
Creation of test-volume has been successful
Please start the volume to access dataglusterfs01 和glusterfs02 和glusterfs03 组成分布式
glusterfs04 和glusterfs05 和glusterfs06 组成分布式
然后在组成镜像
Distributed Striped Glusterfs Volume 分布式条带卷
先组条带在组分布
命令:
> gluster volume create NEW-VOLNAME [stripe COUNT] [transport [tcp | rdma | tcp,rdma]] NEW-BRICK...示例:
> gluster volume create test-volume stripe 4 transport tcp
glutserfs01:/guiji/pv1 glutserfs02:/guiji/pv1 glutserfs03:/guiji/pv1 glutserfs04:/guiji/pv1 glutserfs05:/guiji/pv1 glutserfs06:/guiji/pv1 glutserfs07:/guiji/pv1 glutserfs08:/guiji/pv1
Creation of test-volume has been successful
Please start the volume to access data.前4个组成一个条带,然后在组成分布式,组成多少分布式和条带式根据条带数量完成的
