Hi, Seems like cinder is not using the local ceph.

in my last message under the line "On a DCN site if you run a command like this:" I suggested some steps you could try to confirm the image is a COW from the local glance as well as how to look at your cinder config.

Update: I uploaded an image directly to the dcn02 store, and it takes around 10,15 minutes to create a volume with image in dcn02. The image size is 389 MB.

Hi Jhon, I checked in the ceph od dcn02, I can see the images created after importing from the central site. But launching an instance normally fails as it takes a long time for the volume to get created.
When launching an instance from volume the instance is getting created properly without any errors.
I tried to cache images in nova using https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/post_dep... but getting checksum failed error.

Update: After restarting the nova services on the controller and
running the deploy script on the edge site, I was able to launch the VM from volume.
Right now the instance creation is failing as the block device
creation is stuck in creating state, it is taking more than 10 mins for the volume to be created, whereas the image has already been imported to the edge glance.
Try following this document and making the same observations in your environment for AZs and their local ceph cluster.
https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features...
On a DCN site if you run a command like this:
$ sudo cephadm shell --config /etc/ceph/dcn0.conf --keyring /etc/ceph/dcn0.client.admin.keyring $ rbd --cluster dcn0 -p volumes ls -l NAME SIZE PARENT FMT PROT LOCK volume-28c6fc32-047b-4306-ad2d-de2be02716b7 8 GiB images/8083c7e7-32d8-4f7a-b1da-0ed7884f1076@snap 2 excl $
Then, you should see the parent of the volume is the image which is on the same local ceph cluster.
I wonder if something is misconfigured and thus you're encountering the streaming behavior described here:
Ideally all images should reside in the central Glance and be copied to DCN sites before instances of those images are booted on DCN sites. If an image is not copied to a DCN site before it is booted, then the image will be streamed to the DCN site and then the image will boot as an instance. This happens because Glance at the DCN site has access to the images store at the Central ceph cluster. Though the booting of the image will take time because it has not been copied in advance, this is still preferable to failing to boot the image.
You can also exec into the cinder container at the DCN site and confirm it's using it's local ceph cluster.
John
I will try and create a new fresh image and test again then update.

Or does it have a bond with everything on it? there is a lot of network traffic between nodes as the hypervisor needs to download the image from Glance. Along with various other services sending normal network traffic, it can be enough to cause issues if everything is running over a single 1Gbe interface. the situation I described, there were dropped packets which resulted in a loss of communication between nova_compute and RMQ, so the node appeared offline. You should also confirm that nova_compute is being disconnected in the nova_compute logs if you tail them on the Hypervisor while spawning the instance. thread: probably would start "tearing down" rabbitmq. I didn't have to do that in a production system yet so be careful. I can think of two routes: this will most likely impact client IO depending on your load. Check out the rabbitmqctl commands. packet list_policies -p the purpose: AMQP trying to privsep privsep privsep privsep
