[Solved] UUID not found, skipping fsck. Raid 0 environment

ziad87 · 2018-12-25 15:59:45

Hello, this is my first post here! I wasn't sure if I should post this inside Installation or not, but I went with here since I'm new.

Anyways, I cannot boot into Arch after I'm done installing. I am using UEFI, and GRUB was installed successfully.
Once it begins booting, it gives me an error about failing to mount the rootfs. Skipping fsck. I'm then dropped into an emergency shell.
If I look inside /dev/ I find /dev/sda and /dev/sdb. These are the 2 drives in my RAID 0 array. /dev/sdc is my live USB. However there is no sign of /dev/md126, my raid0 disk.

Edit: I also had run mkinitcpio -p linux once to fix a weird graphics problem where everything was unreadable.

Here is some more info (these were run in the liveUSB):

Any help would be appreciated!

Did you add mdadm_udev (and maybe mdmon) to the initiramfs? (check "lsinitcpio /boot/initramfs-linux.img")
Can you boot the failsafe initramfs?

ziad87 · 2018-12-25 16:28:28

Hm, no. Ill reboot and check that.
I have already booted the failsafe initramfs, without success.

Thanks for the help!

After adding the mdadm_udev hook, it booted up! Thanks a lot for your help!

Cool.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Edited. Thanks again for your help.
