OpenStack Glance通过add location方式上传镜像到Ceph
前提：
需要将所有控制节点glance中show_multiple_locations设置为true。
/etc/glance/glance-api.conf
show_multiple_locations = true
修改后需要重启glance-api服务
systemctl restart openstack-glance-api
1 创建一个空的镜像记录
glance image-create --visibility public --disk-format raw --container-format bare --name test-image.raw

2 确认本地镜像文件为raw
qemu-img info /root/cirros
image: cirros
file format: raw
virtual size: 39M (41126400 bytes)
disk size: 39M
3 将本地镜像文件导入到ceph
这里上传到compute池，名字保存为镜像id
rbd import /root/cirros compute/1572527c-3282-49cc-a63b-6a67b0898aab
rbd snap create compute/1572527c-3282-49cc-a63b-6a67b0898aab@snap
rbd snap protect compute/1572527c-3282-49cc-a63b-6a67b0898aab@snap
确认镜像文件成功上传到ceph的compute池
rbd ls -l compute |grep 1572527c-3282-49cc-a63b-6a67b0898aab
1572527c-3282-49cc-a63b-6a67b0898aab 40162k
1572527c-3282-49cc-a63b-6a67b0898aab@snap 40162k
4 给空的镜像记录增加location
url格式为rbd://cluster_id/pool_name/image_id/snap
其中cluster_id通过ceph -s查询
ceph -s
cluster d1c2aad7-beda-41aa-b537-833eed731acb
