So I have successfully attached cinder volumes to instances. However, I've noticed that when it asks for the Device Name I.E. /dev/vdc ...I get a message on the Horizon dashboard that says it attached at /dev/sdc or something completely different than what I specified. When I goto the instance and view the volume I noticed a few things:
1. I had to reboot the instance to get it to pick up the volume
2. The volume is showing up as /dev/sdxxx (a device name not indicated on the Dashboard)
3. I assume I have to partition and format these volumes? I noticed when setting up a new volume there is a place for Volume Source which can we either No source, empty volume or Image. How do I go about using the from image?
Is there a way to automate the attachment/mount/partition/format/etc where I don't have to reboot the instance?
