Questions about replacing disk #532

Hi,

Thanks for making btrbk! Running a simple master -> slave snapshot set up here. Got a scenario and a couple of questions:

My setup:

Host 1: "master disk" - Backup data are dumped on this disk. There're 2 subvolumes with backup data: vol1/, vol2/.
Host 2: "slave disk" - Once a day, Host 2 initiates btrbk snapshots and pull from vol1/, vol2/ on Host 1.

Scenario: Host 1 master disk died. I'd like to replace the master disk with a brand new one.

Questions:

I figured out how to use btrbk to send the snapshots from "slave disk" to the new disk, but not sure how to re-create vol1/, vol2/ on the new disk?
Will the re-created vol1/, vol2/ continue to snapshot and send to the slave disk OK?

Thanks!

Answering my own questions - btrfs subvolume snapshot works like a charm to re-create vol1/, vol2/. Just Work (TM)
