Hello.
I'm working on Liberty Openstack environment using
ibm.storwize_svc.StorwizeSVCDriver as volume_drivert.
When I'm creating a new volume and attaching it to the VM - by default it
will be /dev/vdX on the instance using virtio driver.
And this way everything is working fine.
But I need it to be /dev/sdX for my application needs.
I tried to create a new type of the volume by running :
cinder type-create SATA
cinder type-key SATA set volume_backend_name=sata
But when I start a volume create process , it fails - the new volume has
error state and the error in cinder-scheduler.log is :
ERROR cinder.scheduler.flows.create_volume Failed to run task
cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create:
No valid host was found. No weighed hosts available
Please advise how a volume can be attached as /dev/sdX device and not
/dev/vdX.
The solution of stop the VM first and only then attach a volume can also
be taken in account.
Thank you.
