I am trying to compile a kernel for a server that uses SCSI drives. I |
| 2 |
followed the Gentoo documentation for building a kernel, specifying all |
| 3 |
the appropriate SCSI low-level drivers with |
| 4 |
|
| 5 |
make menuconfig |
| 6 |
|
| 7 |
then |
| 8 |
|
| 9 |
make dep && make bzImage modules modules_install |
| 10 |
|
| 11 |
and copied bzImage over to /boot/kernel-2.4.22-gentoo-rc5. |
| 12 |
|
| 13 |
When I boot with the new kernel, it dies on |
| 14 |
|
| 15 |
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0 |
| 16 |
ds: no socket drivers loaded! |
| 17 |
VFS: Cannot open root device "sda5" or 08:05 |
| 18 |
Please append a correct "root=" boot option |
| 19 |
Kernel panic: VFS: Unable to mount root fs on 08:05 |
| 20 |
|
| 21 |
The "root=" kernel option is set correctly in /boot/grub/grub.conf so I |
| 22 |
am a bit mystified. |
| 23 |
|
| 24 |
Someone mentioned to me that I need to make an initrd for SCSI because |
| 25 |
of some chicken-and-egg problem during boot. Here I'm a bit stuck |
| 26 |
because I don't see much documentation on initrd in the Gentoo |
| 27 |
installation docs other than in the mention of genkernel. |
| 28 |
|
| 29 |
(I tried genkernel, by the way, and booting with the kernel and initrd |
| 30 |
it produces got me to a shell in the initrd ramdisk but wouldn't |
| 31 |
recognize my root device.) |
| 32 |
|
| 33 |
I found the mkinitrd ebuild but it doesn't clear things up that much. |
| 34 |
It talks about "scsi_hostadapter entries in /etc/modules.conf" but I |
| 35 |
don't see any scsi_hostadapter entries in my modules.conf. Do I need to |
| 36 |
run modules-update or something? (I tried running it and modules.conf |
| 37 |
was left unchanged with no scsi_hostadapter entries.) And do I need to |
| 38 |
toggle any settings in the kernel to indicate that I'm using initrd or |
| 39 |
does it figure that out from the initrd setting in grub.conf? |
| 40 |
|
| 41 |
Is there any good documentation that anyone knows of that explains how |
| 42 |
to compile a kernel on Gentoo if you're working with SCSI drives? Can |
| 43 |
anyone give me an example set of commands one would go through in this |
| 44 |
process? This is an area I'm not really familiar with as you can |
| 45 |
undoubtedly tell .... |
| 46 |
|
| 47 |
Thanks, |
| 48 |
