btrfs device scan returns nothing?

btrfs device scan returns nothing?

[Neal Becker]

What am I doing wrong?

sudo btrfs device scan

Scanning for Btrfs filesystems
[silence]

But I'm running on btrfs now:

--- /etc/fstab
UUID=7246327b-1905-4fe2-9b6b-b9376017264f /                       btrfs   
subvol=root     1 1
UUID=2c04be93-34c1-4016-ba41-60fd9fd90616 /boot                   ext4    
defaults        1 2
UUID=7246327b-1905-4fe2-9b6b-b9376017264f /home                   btrfs   
subvol=home     1 2

   Nothing wrong -- that's what it's meant to do.

   It tells the kernel about the filesystems it finds, not the
user. If you want to do a scan and show the filesystems on the current
machine, btrfs fi show is the tool you need.
