分布式存储系统之Ceph集群部署( 七 ) _生活百科

提示：create可以指定数据盘，日志盘以及block-db盘和bluestore 日志盘等信息；
将ceph-mon01的/dev/sdb盘添加为集群osd
[cephadm@ceph-admin ceph-cluster]$ ceph-deploy osd create ceph-mon01 --data /dev/sdb查看集群状态

文章插图
提示：可以看到现在集群osd有一个正常，存储空间为80G；说明我们刚才添加到osd已经成功；后续其他主机上的osd也是上述过程，先擦净磁盘，然后在添加为osd；
列出对应主机上的osd信息

管理osd ceph命令查看osd相关信息
1、查看osd状态
[root@ceph-mon01 ~]#ceph osd stat10 osds: 10 up, 10 in; epoch: e56提示：osds表示现有集群里osd总数；up表示活动在线的osd数量，in表示在集群内的osd数量；
2、查看osd编号
[root@ceph-mon01 ~]# ceph osd ls0123456789[root@ceph-mon01 ~]#3、查看osd映射状态
