Thanks Stroller. I saw a web page where Google announced this December |
| 12 |
that they were going to be using it. I figured I might as well finally |
| 13 |
get on board. |

The next thing I need to understand is the initramfs stuff. My |
| 16 |
existing RAID1 (md5 below, 3 disks) uses a 0.90 Super Block which get |
| 17 |
auto-assembled by the kernel at boot. The new RAID6 (md3 below, 5 |
| 18 |
disks) uses Ver 1.2 which, as I understand it, won't get |
| 19 |
auto-assembled and requires the initramfs. I'm currently going through |
| 20 |
the Gentoo docs to learn about setting that up. |
