Re: ERROR: error removing the device '/dev/sdXN' - Inappropriate ioctl for device

[Anand Jain <anand.jain@oracle.com>]

Martin,

  presumably kernel failed to read SB from disk /dev/sdf5,
  bit strange it saw 'Inappropriate ioctl for device',
  logically that don't explain.

  Curios to know what does 'btrfs fi show -d' say ?
  and output of blkid if you could. The situation here
  is not same as destroying the SB though.

Thanks, Anand
