Message definition (Btrfs)

There is an '''easy and secure way''' to move a volume to another disk/device. If you use Btrfs itself to move the volume, there will be no danger. You even can do this '''while the volume is in use'''.
* Create the partition you want to use as ''destination'' '''without formatting''' it. Or remove the filesystem when one is present
* Add the ''destination'' device to your volume by {{RootCmd|command=btrfs device add /dev/[destination] [path to filesystem]}}
* Remove the ''source'' device from your volume by {{RootCmd|command=btrfs device remove /dev/[source] [path to filesystem]}}
Btrfs will notice, that it is necessary for this setup to move all data from the source device to the destination device. And it will start immediately to move data in the background. Meanwhile you can use your PC as you want.
* Empty Blocks will not be moved
* Compressed data will remain compressed
* All Snapshots will remain
* '''The UUID of the filesystem will remain the same''', but btrfs will be aware of this
* If you used the UUID to identify your volume, you even wont´t need to edit '''/boot/grub/grub.cfg''' and '''/etc/fstab'''
* Only, '''don't shutdown while the move of the volume is not complete'''.
If you want to watch the volume move, inside a terminal:
{{UserCmd|command=pamac install procps-ng}}
{{RootCmd|command=watch -n 60 btrfs filesystem show /}}

If you want to watch the volume move, inside a terminal:
{{UserCmd|command=pamac install procps-ng}}
{{RootCmd|command=watch -n 60 btrfs filesystem show /}}

There is an easy and secure way to move a volume to another disk/device. If you use Btrfs itself to move the volume, there will be no danger. You even can do this while the volume is in use.

Create the partition you want to use as destination without formatting it. Or remove the filesystem when one is present
Add the destination device to your volume by
root # btrfs device add /dev/[destination] COPY TO CLIPBOARD

Remove the source device from your volume by
root # btrfs device remove /dev/[source] COPY TO CLIPBOARD

Btrfs will notice, that it is necessary for this setup to move all data from the source device to the destination device. And it will start immediately to move data in the background. Meanwhile you can use your PC as you want.

Empty Blocks will not be moved
Compressed data will remain compressed
All Snapshots will remain
The UUID of the filesystem will remain the same, but btrfs will be aware of this
If you used the UUID to identify your volume, you even wont´t need to edit /boot/grub/grub.cfg and /etc/fstab
Only, don't shutdown while the move of the volume is not complete.

If you want to watch the volume move, inside a terminal:

user $  pamac install procps-ng COPY TO CLIPBOARD

root #  watch -n 60 btrfs filesystem show / COPY TO CLIPBOARD
