tune2fs

[Trevor]

I've got a filesystem that is type btrfs.  When I execute the tune2fs command on it,
I get the following output:

sudo tune2fs -l /dev/sda5
tune2fs 1.47.0 (5-Feb-2023)
tune2fs: Bad magic number in super-block while trying to open /dev/sda5
/dev/sda5 contains a btrfs file system labelled 'fedora'

I have another filesystem that is type ext4.  When I execute the tune2fs coommand on
it, I get the following output:

sudo tune2fs -l /dev/sda2
tune2fs 1.47.0 (5-Feb-2023)

/dev/sda5 filesystem type:  btrfs

/dev/sda2 filesystem type:  ext4

Okay, now that you've been able to wade through all of the preliminary,
my question is, what could possibly be causing the very abbreviated 
output for the /dev/sda5 device?  Oh, by the way,  /devsda5 is my root
filesystem!!!
