IAAS平台Resize失败故障处理

背景

上通服IAAS平台某一实例于2022年05月24日resize错误，初步判定为数据库中数据不一致导致resize时检查卷attach状态错误，现将解决方法总结如下：

故障截图

1.根据实例名查找实例ID与卷ID

source admin-openstack.sh
openstack server list --project project_001|grep entrygo-023
openstack server show e1071139-fa71-42ce-ae79-b93914958ee9

2.修改实例状态

处于error状态的实例必须通过修改数据库表修改实例状态。

mysql -uroot -p
use nova;
SELECT * from instances where uuid='e1071139-fa71-42ce-ae79-b93914958ee9'\G
UPDATE instances SET vm_state='active' where uuid='e1071139-fa71-42ce-ae79-b93914958ee9';
SELECT * from instances where uuid='e1071139-fa71-42ce-ae79-b93914958ee9'\G
exit();

3.分离卷

只能分离状态为available的实例。

nova volume-detach e1071139-fa71-42ce-ae79-b93914958ee9 8dd2af95-5006-43b5-a685-2f1e272fc71c
openstack volume list |grep 8dd2af95-5006-43b5-a685-2f1e272fc71c
openstack server stop e1071139-fa71-42ce-ae79-b93914958ee9

4.重新Resize并Confirm

openstack flavor list

nova resize e1071139-fa71-42ce-ae79-b93914958ee9 c0c67d59-3822-4ebb-9076-3c4eea8062a4
nova resize-confirm e1071139-fa71-42ce-ae79-b93914958ee9
openstack server show e1071139-fa71-42ce-ae79-b93914958ee9

5.重新附加卷

nova volume-attach  e1071139-fa71-42ce-ae79-b93914958ee9 8dd2af95-5006-43b5-a685-2f1e272fc71c
# nova reboot e1071139-fa71-42ce-ae79-b93914958ee9

然后返回dashboard界面硬重启实例即可
