基本操作
集羣節點
擴展集羣
1,必須做hosts域名解析
其實通過IP地址也能做集羣,但是不建議這種方式.
192.168.1.210 glusterfs042, 添加節點到集羣中,在當前所有集羣節點中都需要執行
gluster peer probe glusterfs043,查看對等狀態
gluster peer status查看集羣節點信息
gluster pool list刪除節點
從集羣中刪除節點
gluster peer detach glusterfs04卷
創建卷
distribute volume分佈式卷(默認)
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 條帶卷
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 複製卷(最少兩個節點)
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 分佈式複製卷
命令:
> gluster volume create NEW-VOLNAME [replica COUNT] [transport [tcp | rdma | tcp，rdma]] NEW-BRICK ......示例:
兩個節點組成分佈式,鏡像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 組成分佈式
glusterfs03和glusterfs04 組成分佈式
glusterfs05和glusterfs06 組成分佈式
然後在組成鏡像
三個節點分佈式鏡像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 組成分佈式
glusterfs04 和glusterfs05 和glusterfs06 組成分佈式
然後在組成鏡像
Distributed Striped Glusterfs Volume 分佈式條帶卷
先組條帶在組分佈
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個組成一個條帶,然後在組成分佈式,組成多少分佈式和條帶式根據條帶數量完成的
