The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

根据日志可以看出是openstack-cinder-volume.service服务没起来，因为我前面删掉了原本的loop设备，所以导致这个问题，我们先看下这两个service文件，正确的阅读方式请参见 systemd.unit 中文手册

既然我们已经自己手动创建了cinder-volumes，那么我们就不需要openstack-losetup.service这个脚本了，所以我们把Before+RequiredBy去掉即可
