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.

I'm running Proxmox on a Lenovo ThinkCentre and I decided to swap the internal 256 GB 2,5" SSD for a 500 GB NVME.

I installed the new NVME alongside the old SSD, and formated it in ext4 with a single partition. I then proceeded to 'dd /dev/sda /dev/nvme0n1' and it went through without an error.

My impression was that it would clone all content from the old drive to the new, but it wouldn't boot the new drive. I then logged in and set a boot flag via fstab a, but that only helped me boot but the system gets stuck at "waiting for root file system".

Nothing is lost as the old drive still works fine when installed but how do I complete the swap correctly so I can go NVME-only?

Thank you!

it sounds like the bootloader is installed; but not updated to point to the ramdisk and i'd be surprised if your ramdisk doesn't need a new driver to load the nvme drive since it was created using your old ssd.

also: i'm going to assume that you want 500gb instead of 256gb and i think dd is likely going to give you 256gb since it also copies free space and your drives are not identical; if none of the resizefs commands work, then you'll be stuck at 256gb. in your shoes i would use that live distribution to create that partition (or better yet an lvm) like you already did; copy the data that you want with something like rsync; install grub and allow that bootloader installation to create a new ramdisk for you.

this way you're guaranteed to get all 500gb; the bootloader and ramdisk have the necessary bits to run your nvme and installation; plus, if you go with lvm, you're future proofed since you can add drives to that lvm into perpetuity with each new drive increasing its size or retire old drives without having to remove/re-create the volume and all without having to do any of it again.
