Hi all,
I can't seem to find such answer on the net.
I use mirrored volumes and blkid returns the same UUID for the "raid"
volume and the underlying volumes
/dev/mapper/lvm01-root_mimage_0:
UUID="0b88ad6f-34ed-46d6-abe3-eca0d235b353" TYPE="ext4"
/dev/mapper/lvm01-root_mimage_1:
UUID="0b88ad6f-34ed-46d6-abe3-eca0d235b353" TYPE="ext4"
/dev/mapper/lvm01-root: UUID="0b88ad6f-34ed-46d6-abe3-eca0d235b353"
TYPE="ext4"
Then such ID is used in fstab to mount root based... on UUID.
I wonder how fstab knows that it must use /dev/mapper/lvm01-root and not
the others since the three of them share the same UUID, and if by accident
the others can be erroneusly used/mounted.
Has anyone thought of it? Or it's just me?
Alex
