Title:
resizing an instance - causes the drives to dissapear - With it hung
during reboot
Status in OpenStack Compute (Nova):
New
Bug description:
I have my openstack cluster on Havvana.
Resizing an instance (Deb-7-based) to have more disk space - followed
by a reboot (soft) - causes the drives to dissapear. And the instance
would be hung permanently at the boot screen for it cannot find any
drives.
STEPS:
----------
1. Create an instance (deb-7)
2. Resize the instance - with a flavour to have more disk space.
3. After the instance is resized, the instance is permanently set in "ERROR"
state - eventhough you can take a console of it and login as usual.
amande@axcient:~/VMs/IMAGES$ nova list

None | Running | 172_22-public=172.22.0.49 |
+--------------------------------------+-----------------------+--------+------------+-------------+---------------------------+
4. Reset state of the instance.
amande@axcient:~/VMs/IMAGES$ nova reset-state --active
cc867684-0fe9-48a7-95e9-60890d6e4fd0

None | Running | 172_22-public=172.22.0.49 |
+--------------------------------------+-----------------------+--------+------------+-------------+---------------------------+
5. After it has its state changed, Soft Reboot the instance.
6. right at this stage, the drives are not to be seen. and the
instance will be hung at the boot screen forever- for it cannot find
any drives to mount.
