Re: [Openstack-operators] [tags] Appealing for change of tags

[Shamail Tahir]

Hi,

We could definitely use more attendance/help on the ops-tag team... The
data in project navigator comes from multiple sources but the install guide
availability[1], packages[2], etc. are derived from ops-tags[3].  The team
meets once a month (3rd Thursday of every month) to review open tags.  I
agree with Tim that we should determine how we can automate the information
collection as much as possible... It's not abandoned but more participation
would be helpful.  We are nearing the point where we should start
populating tags for Mitaka.

[Openstack-operators] [nova] how to recover instances with different hypervisor-id on the same compute node

[Rahul Sharma]

Hi All,

Due to a hostname change, we ended up having a new hypervisor-id for one of
our compute nodes. It was already running two instances and then, we didn't
catch the updated hypervisor-id. This ended up with new instances spawning
up with new hypervisor-id.

Now, the instances with older hypervisor-id are not seen in "virsh list",
rebooting those instances keep them rebooting.

[root (admin)]# nova hypervisor-servers compute-90

[root@compute-90]# virsh list

 325   instance-18f8  running
 336   instance-18fa  running

Instances not visible: instance-0712 and instance-0b74

Is there a way to recover from this step? I can delete the old
services(nova service-delete ), but I am confused whether it will lead
to loss of already running instances with old hypervisor-id? Is there a way
I can update the state of those instances to use hypervisor-id as 92
instead of 40? Kindly do let me know if you have any suggestions.

Thanks.

fullack with both of you. The project guide itself is an awesome idea but don't 
know why, it looks a bit abandoned for now. Would be great if someone - maybe 
from the cross project team(?) - could point out how we all could make things 
better (or even who the right person to talk to is ;)).

[Openstack-operators] [puppet] Puppet OpenStack Community Session in Austin Summit

[Emilien Macchi]

Puppet OpenStack group will have a Community Session during the next
Summit in Austin.

This session is great to gather feedback from anyone in OpenStack community:
* developers can ask questions about how to contribute.
* operators / users can give feedback at how modules work on their deployments.

What we would like during this session is getting a maximum of
feedback about Puppet OpenStack modules:
* what would you like us to develop / improve / fix during Newton?
* how do you use the modules? Do you use Hiera? Which version of
Puppet? Which operating system? Which OpenStack version?

If you are interested by this session, or if you can't attend it but
you have some feedback / questions you want us to discuss, please
look:
https://etherpad.openstack.org/p/newton-community-puppet


Puppet OpenStack team will do their best to get feedback and address
it during Newton cycle, your help is really important!

Thanks,

Re: [Openstack-operators] [nova] create image from paused VM refused with http 409

[Christopher Hull]

I had some interesting experiences between Cinder and Glance with Kilo as
well.  For instance, occasionally I'd get a bad checksum when running an
image created from a Cinder volume.  The checksum would occasionally be
wrong.   Liberty works well.   All my images run no matter what.   But I
can't get a Liberty based Neutron Router to work.  The Public Port is
always Down.  Resorting to dedicating a small instance to be my virtual
router.

Best of luck.  If your problem keeps up upgrade to Liberty.

[Openstack-operators] Avoiding Cinder stampedes with RBD? (Kilo)

[Ned Rhudy (BLOOMBERG/ 731 LEX)]

We have a situation where tenant A is trying to launch large numbers of 
instances from a single RBD volume snapshot in Cinder (e.g., 40 instances at 
once). We made an unrelated change recently to enable 
rbd_flatten_volume_from_snapshot by default in order to save tenants who create 
large chains of volumes and snapshots until they run out of quota and then 
can't figure out how to unwind the chain, because the relationships are not 
trivially traceable. This change appears to be causing tenant A significant 
heartache now, because when he launches some large number of instances at once, 
most of his instance launches time out, presumably because Cinder is stampeding 
onto Ceph and trying to create flattened RBD images for every single instance 
simultaneously.

My question is, is there anything I can do to stop this stampeding? A review of 
cinder.conf options for Kilo didn't point out any obvious setting that could be 
adjusted to force Cinder to serialize its operations here, but maybe I missed 
something.___

Re: [Openstack-operators] [nova] create image from paused VM refused with http 409

[Saverio Proto]

I found the problem. It happens only then the instance has booted from volume.

I think api.py should be patched at the function
snapshot_volume_backed (line 2250) in a similar way as
https://review.openstack.org/#/c/116789/

Looks like the bug is also there in master , file nova/compute/api.py line 2296

I will try to submit a patch with Gerrit

[Openstack-operators] [nova] create image from paused VM refused with http 409

[Saverio Proto]

Hello there,

I used to do this in Juno, and now I upgraded to Kilo and it is not
working anymore.

macsp:~ proto$ openstack server image create --name test
81da19c6-efbe-4002-b4e8-5ce352ffdd14
Cannot 'createImage' instance 81da19c6-efbe-4002-b4e8-5ce352ffdd14
while it is in vm_state paused (HTTP 409) (Request-ID:
req-0e7f339d-a236-4584-a44c-49daed7558ee)

Is this a change of behaviour ?

I also found this:

Should not this work ? my nova-api --version is 2015.1.2
