I followed this guide on migrating an install to a new ssd and this was the result. I still have the original SSD but i’d rather fix this one then reinstall the original and clone it again. I’d be appreciate of any help.
Update 1: I reinstalled my original SSD and am booted into my Arch install. I’ll probably try cloning again from here.
once ran into the same error when I tried reinstalling arch once and my only option to fix it was
btrfs check --repair /dev/nvme0n1p2
WORD OF WARNING THOUGH: could result in data loss. But that did fix the same issue for me.
