Subject: How to change BTRFS filesystem UUID
Date: Mon, 28 Dec 2015 01:31:26 +1100	[thread overview]
Message-ID: <567FF63E.3010106@ganomi.com> (raw)

Hi,

I cloned several machines from the same disk and they all have same 
BTRFS filesystem UUID. I need to recovery one disk from failure, but if 
I attach two disks to the same machine, both disks have the same ID.

This seem to confuse UDEV, because /dev/disk/by-uuid seem to show just 
one link, not two links to two disks.

Is there a way to change the BTRFS ID (generate new one) that I can 
differentiate between the two disks on one host?

Thank you
Jiri
