Heat stack error - when creating a new swarmbay

[Khoi Vo]

Have Liberty Devstack with Magnum running on baremetal server with more than enough resources.

Was able to successfully create a swarmbay no problem for "demo tenant".

Tried to create another Openstack project/tenant and create an additional swarmbay for this tenant. I created a similar bay model and when I tried to create bay, Heat logs showing:

Resource CREATE failed: ResourceInError: resources.docker_volume: Went to status error due to \"Unknown\"

Magnum API logs show:

screen-m-cond.log:2015-11-25 15:12:46.198 ERROR magnum.conductor.handlers.bay_conductor [-] Bay error, stack status: CREATAILED, stack_id: 005318e1-d219-4c4f-aeec-fd0738bb0c3d, reason: Resource CREATE failed: ResourceInError: resources.docker_vme: Went to status error due to "Unknown"

Any ideas?

Thanks
Khoi

Volume has been recently added to swarm bay, but it seems the document is outdated. Could you try to create a new baymodel by specifying the docker-volume-size. Like below:

magnum baymodel-create --name swarmbaymodel \
                       --image-id fedora-21-atomic-5 \
                       --keypair-id testkey \
                       --external-network-id public \
                       --dns-nameserver 8.8.8.8 \
                       --flavor-id m1.small \
                       --coe swarm \
                       --docker-volume-size 5

    Docs: specify --docker-volume-size for swarm bay

    If this option is not specified, the default is 25GB which is too big
    to fail the stack creation.

Hi

I've tried to specify the docker volume size to 5 as requested but still getting heat and m-conductor errors:

"Resource CREATE failed: resources.swarm_masters: ResourceInError: resources[0].resources.docker_volume: Went to status error due to \"Unknown\""

, "stack_status_reason": "Resource CREATE failed: resources.swarm_masters: ResourceInError: resources[0].resources.docker_volume: Went to status error due to \"Unknown\"

Thanks

Several things:

* Does the error reproducible? If yes, could you share the steps the reproduce the error (e.g. the exact set of commands you ran).
* Did you see any error from Cinder? (check c-vol tab) If yes, could you paste the cinder logs?

Indeed, there was a cinder volume error:

had to perform the following to fix:

This issue was fixed in the openstack/magnum 2.0.0 release.
