dashboard疏散主机提示报错：无法疏散主机…处理方法
报错说明【状态卡在reboot状态】
-
前提条件，有个虚拟机控制台刷不出来，以为虚拟机死机了，重启后发现一直卡在重启界面，并且host_status信息也获取不到了。。。
-
后面发现造成这个原因是因为该虚拟机所属的宿主机down机了。。。。但是又因为上面虚拟机一直处于硬重启状态，所以这台虚拟机肯定是无法迁移或疏散出去的。。。。所以疏散主机就会报下面错误咯。
-
疏散主机就提示，错误，无法疏散主机。
解决方法【登录nova数据库修改虚拟机信息】
首先获取nova数据库的密码
控制节点执行：grep mysql /etc/nova/nova.conf ，如下，Changeme_123就是密码
[root@controller01 nova]# grep mysql /etc/nova/nova.conf
connection = mysql+pymysql://nova:Changeme_123@controller01/nova_api
#connection=mysql://nova:nova@localhost/nova
# by the server configuration, set this to no value. Example: mysql_sql_mode=
#mysql_sql_mode=TRADITIONAL
connection = mysql+pymysql://nova:Changeme_123@controller01/nova
# by the server configuration, set this to no value. Example: mysql_sql_mode=
#mysql_sql_mode=TRADITIONAL
# by the server configuration, set this to no value. Example: mysql_sql_mode=
#mysql_sql_mode=TRADITIONAL
登录nova数据库并做修改
- 命令
mysql -unova -p，密码就是上面查到的。 然后执行查询操作use nova;#进入nova数据库select * from instances where uuid='15beda0e-8a5a-47a8-976c-98c30f316d3b'\G#，查询虚拟机，uuid要修改哦update instances set task_state='NULL' where uuid='15beda0e-8a5a-47a8-976c-98c30f316d3b'\G# 修改虚拟机状态，task_state参数确认你上面查询的有没有这个值【这个值是记录虚拟机状态信息的：如这位task_state: rebooting_hard】，然后后面的uuid也的同步修改。 【修改task_state后nova show命令可以看到status状态也会同步改变，其实我们可以在控制节点用命令单独修改status状态，但task_state不会跟着改变。】
[root@controller01 nova]# mysql -unova -p

再次迁移并验证
- 其实这个时候疏散主机还是提示，错误，无法疏散主机。
- 但不完全错误，因为4台已经迁出去2台了，还剩2台没迁移出去。 底层看到02这个宿主机上没迁移出去的虚拟机有一台为
ERROR，所以大概已经知道是因为ERROR这个虚拟机导致迁移失败了。 至于另外一个正常的为啥没迁移出去，因为到ERROR那台就卡主了，所以正常那台也没迁移出去。 处理和验证接着往下看

- 问题定位到了，因为这个error的虚拟机导致这2台都迁移失败了。尝试去数据库修改状态和底层用命令修改状态，都是，疏散就报错。。。。 大概率是这个虚拟机本身就损坏了。
解决方法
- 所以这个error的虚拟机是没解决的，这个虚拟机2021年就是关机状态了，也没人用，所以这个迁移就ERROR状态的虚拟机，直接就删除了。 【不解决这个虚拟机，迁移就乎会一直报错啊，因为到这就卡住了，后面虚拟机就疏散不了】
再次迁移并验证
- 直接再次迁移
成功
- 底层查看compute02【down机的主机】是否没虚拟机了
[root@controller01 ~]# nova list --all --host computer02

- 再登录到迁移的目标主机上，查看新主机是否存在，存在查出uuid，nova show看到ip后，去dashboard上进入控制台，看虚拟机系统是否正常。如果都正常，问题解决。
