Well, it's not specific to Qubes OS, but maybe you'd like to read this:
Setting up a HA cluster using Xen PVMs recently, I found a bug that 
activated one VM on two nodes at the same time... The VM was using BtrFS 
as root / boot filesystem with many subvolumes and automatic snapshots 
before each software update.
As a result the BtrFS was corrupted, and there was NO way to recover any 
of the snapshots or subvolumes. Maybe keep this in mind. In the past I'd 
traditionally use separate ext2/3 filesystems for things like /, /boot, 
/var, etc. And the changes to recover something are probably higher than 
with BtrFS... Anyway: I just wanted to tell.


Regards,
Ulrich

Hi I recently upgraded to a new primary HD and these are the steps 
I've taken:

1. plug the new HD in via USB
2. boot from debian live
3. use dd to copy my entire old HD to new HD
4. use gdisk to convert from MBR to GPT
5. use gparted to move the swap partition to the end of the drive, and 
resize the primary partition to use the remaining space

6. swap in the new HD

I read I need to resize the LVM thin pool but, I'm not seeing the 
right output from lvs.

I also have a second 2TB drive with a second pool.

lsblk output:

Where have my Qubes on the first HD gone? They still work, but I don't 
see them in the output of these commands.

For the record it's:

sudo btrfs filesystem resize +1t /
sudo btrfs filesystem resize +100g /
sudo btrfs filesystem resize +10g /
etc
Just keep spamming until it gives you errors.
