Block Device Naming Randomly On Every

Problem:

After installing the Arch Linux the Block Device Name such as /dev/sda changed to /dev/sdx randomly. That make you fall to rescue mode.

 

Reason:

The command to generate the fstab

genfstab -p /mnt >> /mnt/etc/fstab Boot

will use the Block Device Name instead of the Device UUID. Because of that the kernel can’t mount the / correctly.

 

Solution:

open the /etc/fstab and change all the /dev/sdXX to it corresponding UUID.

 

 

 

 

 

 

 

Useful Commands:

list all the block devices

#lsblk

 

find out the UUID of each device

#blkid
