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?
@Cenzorrll For comparison of LVM with BTRFS there are several article available.

From personal experience, I have an encrypted software RAID1 with mdadm and BTRFS on top.
Is not LVM, but same direction.
Before implementing this, I made some tests.
Related to encryption, when RAID1 was implemented with BTRFS, the CPU load had been doubled, because every BTRFS disk has an encryption process.
With software RAID1, only one encryption process is there.
