Supermicro workstation, Debian Buster

Mounting disks isn't working with UUIDs. At boot or manually mounting:

UUID=301d6d6d-6782-4be3-b979-0cb595ef1a48	/backupDisk	ext4	default 		1	1

says:

mount: /backupDisk: wrong fs type, bad option, bad superblock on /dev/sde1, missing codepage or helper program, or other error.

Both mountings work fine with:

/dev/sde1					/backupDisk	ext4	default 		0	0

The UUID line was copied from "https://wiki.debian.org/fstab" -- and changed a little (the 1s in the line are from the website).  The sd line is what I've been using for years.

The fstab:

# <file system>					<mount point>   <type>  <options>               <dump>  <pass>
# / was on /dev/md0p1 during installation
# root drive (RAID /dev/sda1 and /dev/sdc1)
/dev/md0p1					/               ext4    errors=remount-ro	0	1
# misc
# UUID=2e7a5901-597e-4ea2-92fb-614d07280b20	/blackHole	ext4	default			0	0
# UUID=4e88a5ab-0a0a-491c-ac00-e9d20b66fba7	/mnt		ext4	default			0	0
# backup disk
UUID=301d6d6d-6782-4be3-b979-0cb595ef1a48	/backupDisk	ext4	default 		1	1
### /dev/sde1					/backupDisk	ext4	default 		0	0
# cd drive
/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto		0	0

The manual 'mount /backupDisk' works with the sd version.  It gives the same error using the UUID id.

I've used the UUID version before, on Buster, and I swear it worked.  Any ideas??

The only fstab line where 1 belongs in the pass column is the / filesystem. The
rest should be 0 or 2. The dump column should be 0 unless you need that filesystem
dumped. Most configurations don't need dumped.

I don't see any effect of having the extra "1" fields on mounting.
BTW I trim off any 0 in the last field, which basically means that
a final 0 0 can be omitted, as it's the default. Less cluttered.

But I would like to see the output from:

$ ls -l /dev/disk/*/301d6d6d-6782-4be3-b979-0cb595ef1a48

If nothing is produced, then try the following:

$ ls -lR /dev/disk | grep sde1

Some people might like to obfuscate (or remove) the line that
contains the model name and serial number of the disk.

Cheers,
David.

I don't either, which is why I didn't remove them.  I just changed them to zeros, just so there'll be something there ... I just tried 'mount /backupDisk' again (with the zeros), and there's no difference.

lrwxrwxrwx 1 root root 10 May  8 12:10 /dev/disk/by-uuid/301d6d6d-6782-4be3-b979-0cb595ef1a48 -> ../../sde1

(The UUID's the same as in fstab.)

What happens if you put the following into /etc/fstab?

UUID=301d6d6d-6782-4be3-b979-0cb595ef1a48 /backupDisk ext4 default 0 0

"wrong fs type..."  Like before when it was tabs instead of spaces.

Is it possible that ext4 is the wrong file system type for that partition?

Nope, unless gparted is bent -- just looked.

My bad -- default options is spelled 'defaults'.

UUID=301d6d6d-6782-4be3-b979-0cb595ef1a48 /backupDisk ext4 defaults 0 0
