I'm now trying to merge an existing cinder volume to another system's cinder volume.

In the current system I am using has two nodes running cinder, for example CINDER-NODE-A and CINDER-NODE-B. And I am now planning to add one more cinder node, CINDER-NODE-C, however after adding it I want to merge the cinder volume in CINDER-NODE-A to CINDER-NODE-C, and then remove the cinder service in CINDER-NODE-A. Therefore, as a result there will be two cinder nodes running.

I did some search on internet, but I couldn't find any good ideas. I've found that a cinder volume migration feature will be released in the Havana, but for now I want to do this on Grizzly platform.

Is there any way to migrate a cinder volume to another system within grizzly ?

In Grizzly there's really no built in way to do what you want here. You'd have to hack on the code and modify the DB manually. It is possible, but involves manual hacking etc.

Thank you for your answer. Indeed, as you've mentioned, I had to do some manual hacks, and luckily it worked!
