Subject: Determining subvolumes
Date: Wed, 26 Dec 2012 08:38:54 -0500	[thread overview]
Message-ID: <50DAFDEE.3030204@czarc.net> (raw)

I know that I can find out what btrfs "volumes" are on a system with the 
command:
      btrfs  fi  show

I can also check if a partition of disk is a btrfs volume with the command:
      blkid  -o value -s TYPE /dev/<disk|partition>

And, if I mount that btrfs volume with something like:
      mount -t btrfs /dev/<btrfs>  /mnt/btrfs

The, I can get a list of btrfs subvolumes on that volume with the command:
      btrfs  subvolume  list  /mnt/btrfs

My question:  Is there a way of finding out what subvolumes are defined 
on a btrfs volume without mounting the volume?
