hi,all
i use the UUID option to mount the btrfs disk,but i can not success.
first, the disk is /dev/sdd1
then, i pull out the disk
and after mintues, pushed it again,at this time, it changes to /dev/sde1
but the UUID didn't change.
why i can not mount it successfuly?
the starce file attached.
thanks!
