Read: In the name of thy Lord Who createth, Createth man from a clot. Read: And thy Lord is the Most Bounteous, Who teacheth by the pen, Teacheth man that which he knew not. Nay, but verily man is rebellious That he thinketh himself independent!. Lo! unto thy Lord is the return. (Sura Alalaq 96:8)

Force grub2 to not use UUID

Created On: 02 Nov, 2016: 14:00:39 - Tags : server management


It describes how to update grub2 so it does not use the disk UUID but instead uses the disk physical path. When restoring backup of virtual machine, the backup process may create a new disk with a new UUID.

The server may not reboot if the UUID of the new disk is different from the UUID of the old disk. One possible solution is to ensure that /etc/fstab file uses physical paths instead of UUID. Another solution is to update grub configuration so it uses physical device paths e.g /dev/xvda1 instead of UUID of disk
