Title:
  multipath creates binding for Removable(USB) drives

Status in multipath-tools package in Ubuntu:
  In Progress
Status in multipath-tools source package in Trusty:
  Triaged

Bug description:
  On a system with a multipath configuration, multipath bindings are
  being created for removable(USB) drives rendering them inaccessible as
  normal removable drives.

  in this case, the usb drive is detected as /dev/sdi:

  # lsblk|grep -A2 sdi
  sdi                        8:128  1  14.7G  0 disk  
  ├─sdi1                     8:129  1  14.7G  0 part  
  └─mpath4 (dm-9)          252:9    0  14.7G  0 mpath 
    └─mpath4-part1 (dm-10) 252:10   0  14.7G  0 part  

  # cat /etc/multipath/bindings 
  # This file was created by curtin while installing the system.
  mpath0 1IBM     IPR-0   5EC2590000000080
  # End of content generated by curtin.
  # Everything below is maintained by multipath subsystem.

  mpath3 1IBM     IPR-0   5EC2590000000020

  Upon trying to format /dev/sdi1:

  # mkfs.ext4 /dev/sdi1
  mke2fs 1.42.9 (4-Feb-2014)
  /dev/sdi1 is apparently in use by the system; will not make a filesystem here!
