Irrelevant.
Debian thought it relevant enough to mention in a warning(error?)
message.
Not Debian. Just tune2fs, as a hint suggesting that maybe you specified
the wrong device.
I get the following error message:
root@fromdell:/home/richard# tune2fs -l /dev/sda
tune2fs 1.43.4 (31-Jan-2017)
tune2fs: Bad magic number in super-block while trying to open /dev/sda
Found a dos partition table in /dev/sda
You must specify the partition containing the filesystem, not the
whole disk.
The man pages for fdisk, parted, sfdisk, tune2fs, and dumpe2fs each give
"device" as a possible parameter. Only the last two balk at it.
"Device" is in the generic sense of Unix block device. Not just a whole
disk, but also a partition, logical volume, RAID array, encrypted volume...
fdisk, parted and sfdisk manage partition tables and expect a device
containing a partition table.
tune2fs and dumpe2fs manage ext* filesystems and expect a device
containing an ext* filesystem.
