I have 3 partitions which were previously RAID-1. I've already failed |
| 26 |
one drive so at this moment it's a 2-drive RAID-1. I'm attempting to |
| 27 |
get those two remaining 2 partitions converted to RAID-5 the command |
| 28 |
suggested on the RAID list for doing that isn't working for me. |
| 29 |
|
| 30 |
Once the 250GB RAID-1 is converted to RAID-5 i have to add a new drive |
| 31 |
back in to become a 3-drive RAID-5. The drive I add will be the drive |
| 32 |
I just failed. |
