A big part of my struggles over the last few days has been with mdadm |
| 18 |
& RAID1. I'm learning that we don't want to send someone down that |
| 19 |
path unless he has the right sort of disks. I'm having to deal with |
| 20 |
returns and reordering due to this. |

People should be aware of what is really required to do RAID before |
| 23 |
they get started so they don't duplicate my trials. I wasn't and I'm |
| 24 |
paying for it. (Almost literally if I don't get the drives in the |
| 25 |
mail!) ;-) |
