| 26 | Unmap by device | |
| 27 | =============== | |
| 28 | ||
| 29 | Unmap by device (img is already mapped): | |
| 30 | ||
| 31 | $ rbd showmapped | |
| 32 | id pool image snap device | |
| 33 | ? rbd img - /dev/rbd? (glob) | |
| 34 | $ sudo rbd unmap $DEV | |
| 35 | $ rbd showmapped | |
| 36 | ||
| 37 | Unmap by device partition: | |
| 38 | ||
| 39 | $ DEV=$(sudo rbd map img) | |
| 40 | $ rbd showmapped | |
| 41 | id pool image snap device | |
| 42 | ? rbd img - /dev/rbd? (glob) | |
| 43 | $ sudo rbd unmap ${DEV}p1 | |
| 44 | $ rbd showmapped | |
| 45 | ||
| 46 | $ DEV=$(sudo rbd map img) | |
| 47 | $ rbd showmapped | |
| 48 | id pool image snap device | |
| 49 | ? rbd img - /dev/rbd? (glob) | |
| 50 | $ sudo rbd unmap ${DEV}p5 | |
| 51 | $ rbd showmapped | |
| 52 | ||
| 53 | Not a block device - random junk prefixed with /dev/ (so it's not | |
| 54 | interpreted as a spec): | |
| 55 | ||
| 56 | $ sudo rbd unmap /dev/foobar | |
| 57 | rbd: '/dev/foobar' is not a block device | |
| 58 | rbd: unmap failed: (22) Invalid argument | |
| 59 | [22] | |
| 60 | ||
| 61 | Not a block device - device that's just been unmapped: | |
| 62 | ||
| 63 | $ DEV=$(sudo rbd map img) | |
| 64 | $ sudo rbd unmap $DEV | |
| 65 | $ sudo rbd unmap $DEV | |
| 66 | rbd: '/dev/rbd?' is not a block device (glob) | |
| 67 | rbd: unmap failed: (22) Invalid argument | |
| 68 | [22] | |
| 69 | ||
| 70 | A block device, but not rbd: | |
| 71 | ||
| 72 | $ sudo rbd unmap /dev/[sv]da | |
| 73 | rbd: '/dev/?da' is not an rbd device (glob) | |
