+Unmap by device
+===============
+
+Unmap by device (img is already mapped):
+
+  $ rbd showmapped
+  id pool image snap device    
+  ?  rbd  img   -    /dev/rbd?  (glob)
+  $ sudo rbd unmap $DEV
+  $ rbd showmapped
+
+Unmap by device partition:
+
+  $ DEV=$(sudo rbd map img)
+  $ rbd showmapped
+  id pool image snap device    
+  ?  rbd  img   -    /dev/rbd?  (glob)
+  $ sudo rbd unmap ${DEV}p1
+  $ rbd showmapped
+
+  $ DEV=$(sudo rbd map img)
+  $ rbd showmapped
+  id pool image snap device    
+  ?  rbd  img   -    /dev/rbd?  (glob)
+  $ sudo rbd unmap ${DEV}p5
+  $ rbd showmapped
+
+Not a block device - random junk prefixed with /dev/ (so it's not
+interpreted as a spec):
+
+  $ sudo rbd unmap /dev/foobar
+  rbd: '/dev/foobar' is not a block device
+  rbd: unmap failed: (22) Invalid argument
+  [22]
+
+Not a block device - device that's just been unmapped:
+
+  $ DEV=$(sudo rbd map img)
+  $ sudo rbd unmap $DEV
+  $ sudo rbd unmap $DEV
+  rbd: '/dev/rbd?' is not a block device (glob)
+  rbd: unmap failed: (22) Invalid argument
+  [22]
+
+A block device, but not rbd:
+
+  $ sudo rbd unmap /dev/[sv]da
+  rbd: '/dev/?da' is not an rbd device (glob)
+  rbd: unmap failed: (22) Invalid argument

+
+Need an arg:
+

+  [22]
+
+
+Two images
+==========
+
+Unmap img first:
+
+  $ sudo rbd map img
+  /dev/rbd? (glob)
+  $ sudo rbd map anotherimg
+  /dev/rbd? (glob)
+  $ rbd showmapped
+  id pool image      snap device    
+  ?  rbd  img        -    /dev/rbd?  (glob)

+  $ sudo rbd unmap img
+  $ rbd showmapped
+  id pool image      snap device    
+  ?  rbd  anotherimg -    /dev/rbd?  (glob)
+  $ sudo rbd unmap anotherimg
+  $ rbd showmapped
+
+Unmap anotherimg first:
+
+  $ sudo rbd map img
+  /dev/rbd? (glob)
+  $ sudo rbd map anotherimg
+  /dev/rbd? (glob)
+  $ rbd showmapped
+  id pool image      snap device

+  ?  rbd  img   -    /dev/rbd?  (glob)
+  $ sudo rbd unmap img
+  $ rbd showmapped
+
+
+Image and its snap
+==================
+
+Unmap the image first:
+
+  $ sudo rbd map img
+  /dev/rbd? (glob)
+  $ sudo rbd map img@snap
+  /dev/rbd? (glob)
+  $ rbd showmapped
+  id pool image snap device

+  id pool image snap device    
+  ?  rbd  img   snap /dev/rbd?  (glob)
+  $ sudo rbd unmap img@snap
+  $ rbd showmapped
+
+Unmap the snap first:

+  ?  rbd  img   -    /dev/rbd?  (glob)
+  $ sudo rbd unmap img
+  $ rbd showmapped
+
+
+Two snaps of the same image
+===========================
+
+Unmap snap first:
+
+  $ sudo rbd map custom/img@snap
+  /dev/rbd? (glob)
+  $ sudo rbd map custom/img@anothersnap
+  /dev/rbd? (glob)
+  $ rbd showmapped

+  ?  custom img   anothersnap /dev/rbd?  (glob)
+  $ sudo rbd unmap custom/img@anothersnap

+  $ sudo rbd unmap custom/img@anothersnap

+  id pool   image snap device    
+  ?  custom img   snap /dev/rbd?  (glob)
+  $ sudo rbd unmap custom/img@snap
+  $ rbd showmapped
+
+
