通过 Juju 部署 Openstack 后，ceph-osd 被阻止
$: juju status
ceph-osd/0 blocked idle 1 10.20.253.197 No block devices detected using current configuration
ceph-osd/1* blocked idle 2 10.20.253.199 No block devices detected using current configuration
ceph-osd/2 blocked idle 0 10.20.253.200 No block devices detected using current configuration
我已经通过 juju ssh 连接到了第一台带有 ceph-osd/0 的机器
$: juju ssh ceph-osd/0
我运行以下命令：
$: sudo fdisk -l

如果我们的环境已经部署，我已经决定使用这两个任务：
1°任务

我也为另一台机器 ceph-osd/1 和 ceph-osd/2 重复了此任务
2°任务
在 Juju Gui 上，我已在 3 ceph-osd 上将 /dev/vdb1 中的字符串 /dev/sdb 更改，保存并提交
现在其自身状态为“空闲”

而如果我们必须运行 Openstack 的部署，在此之前，我们必须在 Juju Ui 中将字符串 osd-devices（字符串）从/dev/sdb到/dev/vdb在 3 ceph-osd 中。然后我们可以继续提交。
答案2
ceph-base 的默认磁盘路径当前设置为：“/dev/sdb”。您必须将其设置为 ceph-osd 数据磁盘的路径（“/dev/vdb”）：
$ juju config ceph-osd osd-devices
/dev/sdb
$ juju config ceph-osd osd-devices='/dev/vdb'
配置磁盘时，磁盘上不应有任何分区。此后，ceph-osds 应变为活动状态。
