Open Stack

HI,

I can launch an instance, when using the option "boot from image" and then I just choose one from the list i.e. UbuntuServer1404.
But I get an error when choosing the option  "Boot from image (creates new volume)"

This stats according to "nova hypervisor-stats" show I'm out of free disk space.
i.e. the "free_disk_ge" is negative and the number is -864.

root at opst-ctrl1-dev:/# nova hypervisor-stats

| vcpus_used                   | 72     |

The stats in Horizon are coherent with these stats,
When I look at the
Admin->Hypervisors->Hypervisor Summary
I see the same restult

Disk Usage
Used 1.2TB of 386GB

i.e. the result is -814 (negative).

But my vg0 volume groups on all computer nodes still have plenty of space left, i.e. some 80+ GB.
According to the error, it has to do with the cinder servcie (block device)  ;

Error: Failed to launch instance "yp-test-33": Please try again later [Error: Build of instance be93dfeb-02eb-4ebb-989d-c033f24b5191 aborted: Failure prepping block device.].


I've created cinder-volumes on all computer nodes, and each cinder volume group has 800 GB disk.

Disk Usage
Used 1.2TB of 386GB


When I look at the "cinder stats" I can not find

But for this particular tenant ( which I used when trying to launch the instance) , this is the usage,
and there should be enough resources,

root at opst-ctrl1-dev:/# cinder quota-usage 7c0b82b2ace9471c92ae87f675e562f6

|  Property | Value |
+-----------+-------+
| gigabytes |  2000 |
| snapshots |   30  |
|  volumes  |   30  |

Can anyone please help me on this matter?  What stats am I missing?

Best regards
Yngvi
