I have a HDD from my old openmediavault (based on Debian Jessie) machine with GPT ext4 format. I used it in my new ubuntu machine and try to mount it in fstab but odd things happened. If I mount it by /dev/sdb1, it works. But, if I mount it by UUID, the booting always fails. Anyone had the same problem? Thanks.
My sudo blkid /dev/sdb1 as:
/dev/sdb1: LABEL="HD0103T" UUID="adc291f2-b240-4b85-92af-ab2f7df0b831" TYPE="ext4" PARTUUID="ba0451ca-d562-4a7a-a21e-ca52c1f0e5ae"
and my /etc/fstab mount line as(If I replace the uuid part with "/dev/sdb1", it works):
UUID=adc291f2-b240-4b85-92af-ab2f7df0b831 /media/cwy/HD0103T ext4 defaults 0 2
