Liberty :cinder issue comes when trying to create multiple instances at the same time

[ Edited ]

This is a issue with Orange using Red Hat Openstack platform with CDOT :

 

The process I used is like this: on the OpenStack dashboard I select “Launch instance”, I select to create a new volume for the instance, select the source image to be used (rhel qcow2 image of ~500MB), select instance count x and deploy (instance.jpeg attached)

 

The problem comes when I try to create more than 4~5 instances, because the instance creation process fails, giving an error on the block mapping device (“Error: Failed to perform requested operation on instance "qwe-2", the instance has an error status: Please try again later [Error: Build of instance b4f0e9a4-1da1-433c-9fc7-20a65d47fd99 aborted: Block Device Mapping is Invalid.].”)

 

Looking on the volumes and the instance tabs at the same time, I noticed that the instance creation process times out before the volumes are created. I attached error.jpeg with a snapshot of the instance and the volumes tab at the same moment. As you can see, the volumes are still under construction when the error appears on the instance tab. After ~1 minute all volumes are created successfully, but the instances are already in error so the volumes created after the moment of the picture I sent, are not mapped to any instance.

 

Also, I attached the log of cinder for the operation above.

I noticed here the download operation (download source image of ~500 MB is done at ~200+ MB/s), but the multiplication operation (use the image to put it on all 6 volumes) is done at ~2.4 MB/s.

Is this speed very low or not? Also, I imagine the convert operation is internal (not through the network, but locally on the device).

Also, if I try the same test using a smaller image (~12 MB), I can have it successfully for 10 instances.

 

One quick and dirty workaround would be to change the timeout timers on the OpenStack side, but as far as I read on Red Hat support portal, this is likely to create other issues and they don’t recommend nor support it.

Could you please help?

 

Thank you,

Re: Liberty :cinder issue comes when trying to create multiple instances at the same time

‎2016-09-16 03:17 AM

FYI,

 

We have figured out that it's an issue with the platform overall write sizing. the test required ~500MB per second and this platform is not optimized for suck workload. 

 

NFS caching could be an option instead of using ISCSI for cinder by NetApp driver.
