2、ceph体系架构

3、ceph核心概念

  • Monitors: A Ceph Monitor (ceph-mon) maintains maps of the cluster state, including the monitor map, manager map, the OSD map, and the CRUSH map. These maps are critical cluster state required for Ceph daemons to coordinate with each other. Monitors are also responsible for managing authentication between daemons and clients. At least three monitors are normally required for redundancy and high availability.
  • Managers: A Ceph Manager daemon (ceph-mgr) is responsible for keeping track of runtime metrics and the current state of the Ceph cluster, including storage utilization, current performance metrics, and system load. The Ceph Manager daemons also host python-based plugins to manage and expose Ceph cluster information, including a web-based dashboard and REST API. At least two managers are normally required for high availability.

该组件的主要作用是分担和扩展monitor的部分功能,减轻monitor的负担,让更好地管理ceph存储系统

  • Ceph OSDs: A Ceph OSD (object storage daemon, ceph-osd) stores data, handles data replication, recovery, rebalancing, and provides some monitoring information to Ceph Monitors and Managers by checking other Ceph OSD Daemons for a heartbeat. At least 3 Ceph OSDs are normally required for redundancy and high availability.
  • MDSs: A Ceph Metadata Server (MDS, ceph-mds) stores metadata on behalf of the Ceph Filesystem (i.e., Ceph Block Devices and Ceph Object Storage do not use MDS). Ceph Metadata Servers allow POSIX file system users to execute basic commands (like ls, find, etc.) without placing an enormous burden on the Ceph Storage Cluster.

[root@ceph- ceph]# ceph quorum_status --format json-pretty

8、启用dashboard

启用dashborad

[root@ceph-1 ceph]# ceph mgr module enable dashboard

http://10.213.14.51:7000/

至此整个ceph集群构建完毕,下面测试rbd块存储

[root@ceph-3 ~]# ceph osd pool create test1 128  #创建新的存储池,而不是使用默认的rbd

[root@ceph-3 ~]# rbd create --size 100G image-1 --pool test1 #创建一个快

[root@ceph-3 ~]# rbd info image-1 --pool test1 #查看rbd信息

root@ceph-3 ~]# rbd --pool test1 feature disable image-1 exclusive-lock, object-map, fast-diff, deep-flatten #禁用不支持的属性

[root@ceph-3 ~]# rbd map --pool test1  image-1  #映射块 image-1 到本地

/dev/rbd0

[root@ceph-3 ~]# mkfs.ext4 /dev/rbd0  #格式化块设备

[root@ceph-1 ~]# ceph osd pool application enable test1 rbd

enabled application 'rbd' on pool 'test1'

测试写入数

[root@ceph-3 rbd]# dd if=/dev/zero of=/mnt/rbd/a count=30000 bs=1M

30000+0 records in

30000+0 records out

31457280000 bytes (31 GB) copied, 66.36 s, 474 MB/s

删除ceph

ceph-deploy purge ceph-1 ceph-2 ceph-3

ceph-deploy purgedata ceph-1 ceph-2 ceph-3

ceph-deploy forgetkeys
