Yes, part of the problem is that I can't create a fifth partition. |
| 25 |
However, even if possible, this wouldn't have been my ideal solution |
| 26 |
anyway as it would negate some of the performance benefit gained from |
| 27 |
having one huge partition over the whole array. |

But my real question is, as I've reached the max partition for the msdos |
| 30 |
partition table, can I migrate to a GPT partition table without losing |
| 31 |
my data? |

Cheers, |
