在cinder 集群之外安装 qemu
# 好像需要开启 yum install epel-release -y yum install qemu -y
在 客户 机上 放置 授权文件
qemu-img {command} [options] rbd:glance-pool/maipo:id=glance:conf=/etc/ceph/ceph.conf 由于 qemu 命令 需要 /etc/ceph/ceph.conf 以及 keyring 所以我们去 集群中 取一下 scp -rp root@192.168.141.20:/etc/ceph /etc
创建 image
# 第二个 rbd 是 pool 存储池名称 qemu-img create -f raw rbd:rbd/foo 1G qemu-img create -f raw rbd:rbd/qemu_img_client 1G rbd info qemu_img_client -> rbd image 'qemu_img_client': size 1 GiB in 256 objects order 22 (4 MiB objects) snapshot_count: 0 id: 391b7fcc6093
qemu 查看镜像信息
qemu-img info rbd:rbd/foo -> image: rbd:rbd/foo file format: raw virtual size: 1.0G (1073741824 bytes) disk size: unavailable
qemu resize 镜像
qemu-img resize rbd:rbd/foo 3G
qemu 根据镜像创建 image
