Ceph deploy无法创建osd

Question

我是ceph安装的net专家，并且遵循了一些教程。不幸的是，当我现在尝试执行OSD的命令时。

ceph-deploy osd create --data /dev/vdb node1

我遇到了这个错误

[ceph-vm2][INFO  ] Running command: sudo /usr/sbin/ceph-volume --cluster ceph lvm create --bluestore --data /dev/sdb
[ceph-vm2][WARNIN] -->  RuntimeError: Unable to create a new OSD id

请确保您的/dev/sdb没有首先获得重要数据！

1.

#umount /dev/sdb1 or /dev/sdb2

2.

vim /etc/fstab
common /dev/sdb uuid mount

3.

#parted -s /dev/sdb mklabel gpt mkpart primary xfs 0% 100%

4.

#reboot

5.

#mkfs.xfs /dev/sdb -f

6.

ceph-deploy osd create --data /dev/sdb node1
