rbd 操作小计

#列出指定pool的镜像
root@ceph:~# rbd ls|list [--pool|-p <pool>]

#列出指定pool的镜像
root@ceph:~# rbd rm|remove <image-name> [--pool|-p <pool>]

#新建镜像,可以用-p|--pool参数或者<pool-name>/<image-name>方式指定pool
root@ceph:~# rbd create [<pool-name>/]<image-name> -p|--pool <pool-name> -s|--size <image-size>

#将镜像映射到块设备
root@ceph:~# rbd map [<pool-name>/]<image-name>[@<snap-name>] -p|--pool <pool-name>

#取消映射
root@ceph:~# rbd unmap [<pool-name>/]<image-name>[@<snap-name>] -p|--pool <pool-name>

#调整镜像大小

rados 操作小计

#列出所有pool
root@ceph:~# rados lspools

#创建pool [with auid 123[and using crush rule 4]]
root@ceph:~# rados mkpool <pool-name> [123[ 4]]

#复制pool的内容到另一个poo
root@ceph:~# rados cppool <pool-name> <dest-pool>

#删除pool
