And it even would get funnier if the drive's relocation table |
| 8 |
could be accessed (no idea if this is possible): |
| 9 |
The LVM would notice if the drive has relocated an (LBA) block, |
| 10 |
move it out of the way (somewhere else in the LV) and then |
| 11 |
remove the relocation (never access that LBA block anymore). |
| 12 |
This way an slowly dying disk can be used for quite a long time. |
| 13 |
Think of boxes with very limited physical access (eg. outoor field |
| 14 |
systems) or huge archives w/ non-critical/regeneratable data |
| 15 |
(eg. media collections w/ originals available, mirrors, etc). |

The idea of using even old and damaged disks at really low costs |
| 18 |
(not counting the power consumption ;-P) is seems quite fascinating |
| 19 |
to me :) |
