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

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