我的 openstack 整个环境被我不小心重启了, 重启计算节点出了问题没有启动起来, 我于是想 stop 这个实例, 但是 stop 后, 虚拟机异常了, 如下:

# nova list +--------------------------------------+--------------+--------+--------------+-------------+-----------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+--------------+--------+--------------+-------------+-----------------------+ | 015ac60a-1902-4d39-b4ea-11376838872b | myvm | ACTIVE | None | Running | private=192.168.22.34 | | 72824bed-4ce6-440c-996f-12d725e3fa71 | myvm-on-ceph | ACTIVE | None | Running | private=192.168.22.36 | | a8bdeb86-981f-449e-a529-e6f43314f7dc | myvm2 | ACTIVE | powering-off | Running | private=192.168.22.35 | +--------------------------------------+--------------+--------+--------------+-------------+-----------------------+
# nova stop myvm2 ERROR: Instance a8bdeb86-981f-449e-a529-e6f43314f7dc in task_state powering-off. Cannot stop while the instance is in this state. (HTTP 400) (Request-ID: req-f91e6cfd-bc05-43c8-87e5-5f00bc25f713) |
我把计算节点修复好了, 该虚拟机也一直无法恢复, 这时候只有通过 nova reset-state 先恢复状态了, 该指令会把 instance 的 Task State 恢复为 None, 然后就可以 stop 或者 delete 该虚拟机了.

状态已经修复, 可以 stop && start 了
