Two drives and uefi partition on each drive. How to fix fstab so I can boot each separately?

The situation is like this :




  • Two drives, each with a linux raid partion and an uefi partition with grub installed.

  • The raid partitions are configured as RAID 1 with mdadm

  • Only one drive boots (sda) properly in degraded mode . The other one (sdb) boots in emergency mode.


But I figured out how to fix this. The problem is in the /etc/fstab file.



UUID=64C3-7807 /boot/efi vfat umask=0077 0 1



It points to the UUID of sda. I can boot sdb normally when changing the UUID in the fstab file manually.



How can I fix this permanently so I can boot both drives in degraded mode without having to edit fstab ?






boot grub2 raid
