Hi list, |
| 2 |
|
| 3 |
We're mostly running FreeBSD on our systems but now I'm supposed to |
| 4 |
install a dedicated MySQL server and some benchmarks has shown that |
| 5 |
MySQL runs a lot better in a Linux environment and I especially like |
| 6 |
Gentoo Linux (maybe because it's like FreeBSD in many ways). |
| 7 |
|
| 8 |
Anywho... |
| 9 |
The problem is that I can´t boot the system after a fresh install. |
| 10 |
I may boot the Live CD without problems and from there I can install the |
| 11 |
system. The drives (RAID-1) is shown as device /dev/sdb |
| 12 |
|
| 13 |
(sub question: this cannot be just one of the two drives in the RAID |
| 14 |
right? I guess the PERC won't allow direct access to just ONE drive) |
| 15 |
|
| 16 |
Installation goes just fine and in the kernel configuration I have |
| 17 |
enabled every LSI entry under Device Drivers. But when I boot the system |
| 18 |
it can't mount the root decice: |
| 19 |
|
| 20 |
>> Determining root device... |
| 21 |
!! Block device /dev/sdb3 is not a valid root device... |
| 22 |
!! The root block device is unspecified or not detected. |
| 23 |
|
| 24 |
I have compiled the drivers into the kernel (not as modules). |
| 25 |
I have even tried copying the Live CD kernel and just changed the LSI |
| 26 |
drivers to be compiled into the kernel as opposed to modules. Still no |
| 27 |
luck though. |
| 28 |

Here's a cut from the boot messages: |

If I open the shell (when the kernel can't mount the root device) and |
| 55 |
look into /dev/ I see this: |
| 56 |
# ls /dev/sd* |
| 57 |
/dev/sda /dev/sdb |
| 58 |
|
| 59 |
I appreciate all help I can get |

Thanks, |
