Hi all, I'm playing around with LVMs to expand data storage and I'm looking at what would be required to transfer those drives to another device, all the steps I can find require exporting the volume group and then importing on the other device. But what would be the case if your boot drive were to fail, and you needed to move the drives without being able to export the volume group. Can you just do an import with a new device, or are there other steps required to do so?

Secondly, is there a benefit to creating an LVM volume with a btrfs filesystem vs just letting btrfs handle it?
