[SOLVED] nvme device not found through its UUID

First time installation on a Dell XPS 13 9310.

After rebooting from the live image, I get

Starting version 247.2-1-arch
ERROR: device 'UUID=a2d8cacb-75ea-43d5-b71f-c3812e9141b4' not found. Skipping fsck.
mount: /new_root: can't find UUID=a2d8cacb-75ea-43d5-b71f-c3812e9141b4.
You are now being dropped into an emergency shell.

blkid confirms the UUID of the device. It's also in /etc/fstab and even in the /boot/grub/grub.cfg:

I really hope this isn't embarassingly obvious, but I can't figure out why I don't get to a regular login prompt.

Re: [SOLVED] nvme device not found through its UUID

• Did you run

  mkinitcpio -p linux

• Are the packages in the installation up-to-date?

• Are you sure the nvme is not failing?

Re: [SOLVED] nvme device not found through its UUID

Is your disk configured for RAID in your UEFI? see: https://bugs.archlinux.org/task/68704 and try adding the vmd module to your mkinitcpio

That was it! After checking the output of `hwinfo --storage` and seeing RAID listed in the first storage device, it became clear.

Note that I did not adjust the flags to `mkinitcpio`. Instead, I reconfigured the BIOS as I have no need for the RAID operation mode and simply set it to AHCI. Reinstalled and booted fine. Thanks a lot!

Just curious how you knew this. I searched and read a lot, but it would've taken me much longer to link this problem to RAID settings.

Marking this as solved. Thanks again!

Re: [SOLVED] nvme device not found through its UUID

It's a problem that comes up every now  and then (fairly certain  basically every somewhat modernish dell defaults to that) and if you've been around here for a while and read the posts people make there'll eventually be someone (... like you) that runs into it again, so from that point it's just recognizing the symptoms as something you've seen before.

I've never personally ran into a UEFI set up  this way. But I'd say the link to some setting in the UEFI isn't too far fetched. If you're sure you didn't miss anything during installation, it must be something happening earlier. I did have a similarish experience on my Acer, where it has a UEFI quirk that it doesn't store NVRAM entries added via efibootmgr, but you must add them via their own interface (... in a weird and roundabout way)
