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?
@harsh3466 That should work, as always with dd the potential disaster is getting if and of the wrong way around and wiping the old drive.
No joke! I plan to quadruple check before I hit enter.
Tip: don’t use
/dev/nvme0n1directly, but use device aliases in/dev/disk/. I prefer/dev/disk/by-id/but maybe another works better in your case.# find all aliases for nvme drives (no partitions) find /dev/disk/ -type l -ilname '*nvme?n?' -printf '%l %p\n' | sed 's!^../../!!' | sortThat is actually what I did,
by-id. The whole operation went off without a hitch. I’m up and running with my new 512GB nvme!Congratulations!
Thank you!
The other is not having the sync,noerror options and having a disk error. ddrescue is a lot more forgiving.
