[SOLVED] NVMe Drive not working in Raid On Mode

I have had Arch Linux installed and working on my laptop for about a year now. Every now and then I close the lid and the battery dies. On power up I always have to enter the current time and setup the BIOS settings again. It usually works, however this time now it is failing to boot with the following error:

:: running early hook [udev]
Starting version 244.3-1-arch
:: running hook [udev]
:: Triggering uevents...
Waiting 10 seconds for device /dev/disk/by-uuid/0f44a1ff-b26d-4ba4-80cf-aadec1289f82 ...

There are no sdx entries in /dev

In the grub console the drive shows up (and I can browse the contents of both the efi and root partitions):

When I use a Arch ISO image to obtain a UEFI Interactive Shell v2.2, I can list the current boot entries:

My grub menuentry is doing the following:

insmod part_gpt
insmod ext2
if [ x$feature_platform_search_hint = xy ]; then
  search --no-floppy --fs-uuid --set=root 0f44a1ff-b26d-4ba4-80cf-aadec1289f82
else
  search --no-floppy --fs-uuid --set=root 0f44a1ff-b26d-4ba4-80cf-aadec1289f82
fi
echo    'Loading Linux linux...'
linux   /boot/vmlinuz-linux root=UUID=0f44a1ff-b26d-4ba4-80cf-aadec1289f82 rw  loglevel=3 quiet
echo    'Loading initial ramdisk...'
initrd  /boot/initramfs-linux-fallback.img

When I run the search commands, they do not fail, indicating the UUID is correct.

Some extra details:

The laptop is a Dell Precision 5510 and I replaced its primary drive
with a Samsung 970 Pro M.2 SSD (but it has been working with that change).

It's SATA mode is set to "Raid On" and its setup with UEFI and legacy mode disabled.

The dell ePSA hard drive diagnostic utility says the hard drive is good.

Re: [SOLVED] NVMe Drive not working in Raid On Mode

If you can reproduce the issue with SATA mode set to AHCI then please post the dmesg from the live media.  See tip box from pastebin to post from console.

Doing some reading (https://askubuntu.com/a/473936/189273) I think the mapping table is showing the GUID of the partition table and the UUID is a separate identifier using by Linux to identify a partition. As noted, I can browse the root system partition in the GRUB command-line and view all the files in my home folder and stuff.

When I set to AHCI I can't get into GRUB on the disk but I can boot to the USB live media. In dmesg (http://ix.io/2wKv) I saw the error:

nvme nvme0: missing or invalid SUBNQN field.

Re: [SOLVED] NVMe Drive not working in Raid On Mode

You're always booting the fallback initramfs? Are you sure that's the entry you're using?

I tried this. Doesn't make a difference. Still same UUID disk not found and emergency shell error.

Re: [SOLVED] NVMe Drive not working in Raid On Mode

You're also booting an initramfs from last Feb? What kernel are you on?

Re: [SOLVED] NVMe Drive not working in Raid On Mode

I updated the initial description to add more info about possible cause.

"I have had Arch Linux installed and working on my laptop for about a year now. Every now and then I close the lid and the battery dies. On power up I always have to enter the current time and setup the BIOS settings again. It usually works, however this time now it is failing to boot with the following error:"

Since I am able to chroot in AHCI w/ live media, I am trying a pacman -Syu and updating GRUB and there's some other stuff to try there.

Re: [SOLVED] NVMe Drive not working in Raid On Mode

I was able to perform a full upgrade in chroot and update grub but I'm getting the same behavior. fallback initramfs not working. "Raid On" mode gets me to Emergency shell. Will not boot even into GRUB in "AHCI" mode.

My BIOS is fully up to date but wasn't earlier today but has been for the duration of this thread.

Re: [SOLVED] NVMe Drive not working in Raid On Mode

Fixed.

1. BIOS now set to AHCI mode.
2. Used live image to reformat my EFI partition (didn't change it -- fat32).
3. In arch-chroot, reinstall GRUB
4. Update /etc/fstab to new ESP UUID

Thanks all for the help!
