Dear Maintainer,

I recently tried to resize my home volume, which is a btrfs filesystem
on a lv.  I used the following command:

# lvresize -r -L -75G /dev/RAID/home_vol
fsadm: Filesystem "btrfs" on device "/dev/mapper/RAID-home_vol" is not
supported by this tool
  fsadm failed: 1
  Filesystem resize failed.

It would be nice if this tool supported btrfs.  Resizing btrfs (on a
single block device) is easy (just do btrfs filesystem resize).

thanks,
Brian Minton
