From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Question: Can I use dd to clone my luks encrypted lvm os drive? (lemmy.ml)

EDIT WITH UPDATE: Operation went off without a hitch! I'm now up and running with the 512GB nvme drive! Next stop is dual booting nixos, which was the whole reason for switching to the larger drive.

ORIGINAL POST:

I’ve got a laptop running Arch (btw), with a 128GB nvme in it. The nvme has two partitions. EFI boot, and a luks encrypted lvm.

I’ve got a 512GB nvme I want to swap in. I think I can clone the device with dd, update the uuids, expand the lvm, and drop in the 512 nvme, but my searching hasn't given me a clear confirmation of this. Am I correct in my thought process, or am I setting myself up for disaster?

It is lvm2. Thank you for the recommendation! I'll check it out though I think I'm going to stick to the CLI for this one. I kind of want to do it manually.

I do plan to work from a bootsble USB for all the dd work so that nothing is mounted/in use.
