Launch instance from image (as new volume) fails when giving different size to volume (NoneType' object has no attribute 'update_volume_group_info)

[Dafna Ron]

I tried running a new instance from image (create new volume)
if device size remains 1 we can launch the instance and create the volume.
but if I change the device size to 30 we fail creating the volume with the following error:

I know its an attribute issue but just in case someone asks...

[root@nott-vdsa images(keystone_admin)]# vgs
  VG #PV #LV #SN Attr VSize VFree

Strange, according to this the second time your ran the command the vg member object of your volume driver was not intialized.

Can you please list the commands and steps you performed that lead to this?

If you just did:
    'cinder create --image-id xxxx 1'

Followed by:
    'cinder create --image-id xxxx 30'

I don't see how this is possible, unless you have multiple backend drivers configured, or there were some other operations inbetween there that you performed.

actually I run this from horizon not the cli :)

go to horizon -> instances -> launch instance -> select 'boot from image (create a new volume).

[Rushi Agrawal (rushiagr)]

I too am not able to reproduce the issue with latest devstack. It throws an error 'no valid host found' on c-sch screen, which is expected, but can't find anywhere this message in any log. I'm marking this as invalid. Please try it out with latest devstack, and report back if you still see this issue..

I suspect this was bug 1221874.
