  14 Spell out device instead of using $DEV - sfdisk is not a joke.

  27 Unmap by device
  28 ===============
  29
  30 Unmap by device (img is already mapped):
  31
  32   $ rbd device list
  33   id  pool  namespace  image  snap  device
  34   ?   rbd              img    -     /dev/rbd? (glob)
  35   $ sudo rbd device unmap $DEV
  36   $ rbd device list
  37
  38 Unmap by device partition:
  39
  40   $ DEV=$(sudo rbd device map img)
  41   $ rbd device list
  42   id  pool  namespace  image  snap  device
  43   ?   rbd              img    -     /dev/rbd? (glob)
  44   $ sudo rbd device unmap ${DEV}p1
  45   $ rbd device list
  46
  47   $ DEV=$(sudo rbd device map img)
  48   $ rbd device list
  49   id  pool  namespace  image  snap  device
  50   ?   rbd              img    -     /dev/rbd? (glob)
  51   $ sudo rbd device unmap ${DEV}p5
  52   $ rbd device list
  53
  54 Not a block device - random junk prefixed with /dev/ (so it's not
  55 interpreted as a spec):
  56
  57   $ sudo rbd device unmap /dev/foobar
  58   rbd: '/dev/foobar' is not a block device
  59   rbd: unmap failed: (22) Invalid argument
  60   [22]
  61
  62 Not a block device - device that's just been unmapped:
  63
  64   $ DEV=$(sudo rbd device map img)
  65   $ sudo rbd device unmap $DEV
  66   $ sudo rbd device unmap $DEV
  67   rbd: '/dev/rbd?' is not a block device (glob)
  68   rbd: unmap failed: (22) Invalid argument
  69   [22]
  70
  71 A block device, but not rbd:
  72
  73   $ sudo rbd device unmap /dev/[sv]da
  74   rbd: '/dev/?da' is not an rbd device (glob)
  75   rbd: unmap failed: (22) Invalid argument

 194 Not a mapped spec - random junk (which gets interpreted as a spec):
 195
 196   $ sudo rbd device unmap foobar

 231 Two images
 232 ==========
 233
 234 Unmap img first:
 235
 236   $ sudo rbd device map img
 237   /dev/rbd? (glob)
 238   $ sudo rbd device map anotherimg
 239   /dev/rbd? (glob)

 248   $ sudo rbd device unmap anotherimg
 249   $ rbd device list
 250
 251 Unmap anotherimg first:
 252
 253   $ sudo rbd device map img
 254   /dev/rbd? (glob)
 255   $ sudo rbd device map anotherimg
 256   /dev/rbd? (glob)

 269 Image and its snap
 270 ==================
 271
 272 Unmap the image first:
 273
 274   $ sudo rbd device map img
 275   /dev/rbd? (glob)
 276   $ sudo rbd device map img@snap
 277   /dev/rbd? (glob)

 286   $ sudo rbd device unmap img@snap
 287   $ rbd device list
 288
 289 Unmap the snap first:
 290
 291   $ sudo rbd device map img
 292   /dev/rbd? (glob)
 293   $ sudo rbd device map img@snap
 294   /dev/rbd? (glob)

 303   $ sudo rbd device unmap img
 304   $ rbd device list
 305
 306
 307 Two snaps of the same image
 308 ===========================
 309
 310 Unmap snap first:
