Guys,

I just rebooted one of my compute nodes, and its Instances does not start
anymore.

Logs say:

---
InstanceNotFound: Instance instance-00000011 could not be found.
---

If I try to "Terminate" it, to start over, I'm seeing the following
messages:

---

---

The Logical Volume of that Instance in particular, is still there. I mean,
the file /dev/nova-local/instance-00000011_disk exists.

What can I do?

Thanks!
Thiago
