Alright, so I connected my old linux SSD to my new machine via a USB adapter and only a small partition with OS stuff shows up, not my home / user files.

Edit: had to learn LVM2 nonsense and would around a bug with falsely active groups >_<

@[email protected] you have to first use vgscan to find the name of the volume group and then it should be something like vgchange -ay VolumeGroupName to activate it. And then you can lookup the logical volume with lvs, create a mount point somewhere (just a directory) and THEN mount it mount /dev/VolumeGroupName/LogicalVolumeName /mnt/yourmountpoint

All with sudo, all without breaking your system 🥲

@helpsterTee Thanks. I already just did it though... but there was a bug at the final step so I had to toggle the group on and off. I got my files now.

@[email protected] before turning off the usb drive do
umount /mnt/yourmountpoint
lvchange -an <lvpath>
vgchange -an <vgname>

@[email protected] great! I hate lvm with passion.
