Title:
Hard reboot escalation regression
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Nova used to allow a hard reboot when an instance is already being
soft rebooted. However, with commit
cc0be157d005c5588fe5db779fc30fefbf22b44d, this is no longer allowed.
This is because two new task states were introduced, REBOOT_PENDING
and REBOOT_STARTED (and corresponding values for hard reboots). A soft
reboot now spends most of it's time in REBOOT_STARTED instead of
REBOOTING.
REBOOT_PENDING and REBOOT_STARTED were not added to the
@check_instance_state decorator. As a result, an attempt to hard
reboot an instance which is stuck trying to do a soft reboot will now
fail with an InstanceInvalidState exception.
This provides a poor user experience since a reboot is often attempted
for instances that aren't responsive. A soft reboot is not guaranteed
to work even if the system is responsive. The soft reboot prevents a
hard reboot from being performed.
