Nitpicking: No need for a new volume group, just a new PV. Using a |
| 21 |
separate VG makes migration harder. |

I guess the OP is running the JBOD nature ("linear" in LVM terms). Not |
| 38 |
that it matters, really. |

BTW: Am I the only one seeing a good opportunity for creating a backup |
| 41 |
using the old disks? LVM snapshots would be perfect here, as long as the |
| 42 |
old disks can be kept running. |
