SATA again

dish · Posted: Sun Dec 19, 2004 6:19 am Post subject: SATA again

I successfully installed gentoo with 2.6.9-gentoo-r6 kernel on a SATA mirror 2x160 Seagate on Promise FastTrak 378. After I reboot it says smth like kernel panic... set the right option root=...

What should I do?

Thanx.

Definately more info is needed.
Specifically atleast
your kernel statement in /boot/grub/grub.conf

also your /etc/fstab

To boot in your system, use livecd to boot and mount the partitions
for eg. if your raid is being detected as sda
then mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot

and then just cd into the /mnt/gentoo/boot/grub & /mnt/gentoo/etc to read your files etc.
you could also mount and proc and then chroot if you want to do more work etc.

Refer to gentoo handbook for that if you don't know how to do that..

Also, I am not quite sure how that kernel behaves your chipset. But I ran into an issue with my motherboard, as to when using live cd my raid 1 was being detected as sda but after rebooting the kernel saw it has hda
its funny, I probably just have go through my kernel config again.
but I was originally using gentoo-dev-sources (HD was still detected as sata) and then I switched to hardened-dev-sources and used the same old config file and the hardened kernel detects it as hda
hope this helps

grub.conf:

root (hd1,0)
kernel /vmlinuz-2.6.9-gentoo-r9 root=/dev/sda5

fstab:

/dev/sda1 /boot ext2 noauto, noatime 1 2
/dev/sda2 none swap sw 0 0
/dev/sda5 / ext3 noatime 0 1
/dev/sda6 /usr ext3 noatime 0 1
/dev/sda5 /var ext3 noatime 0 1

Chipset -- intel 865 (Asus p4c800 gold)

Oops, I forgot about one thing:

/dev/hda -- is my another HDD, generic IDE maxtor

So, I should use hdb instead sda? Right?

I'll try right now

it said CRC ERROR
I guess, device is /dev/sda, but for some reason kernel does not see it...

up...

I don't know what else to do... LiveCd works properly and kernel doesn't...

even after genkernel all

it depends on the sata support you used, if you're using the libata, the harddisk will reside in /dev/sdx, if it's the legacy ide-sata, then it will reside in /dev/hdx (probably hde or hdg since the ide probing is reversed)

p.s. i suggest building your own kernel, without using genkernel

Own kernel goes the same... i'm using libata, but why can it be so, that liveCD considers it as sda and my kernel can consider it another?

hybrid · Posted: Sun Dec 19, 2004 11:44 am Post subject:

yes, since there are two implementations for sata :s

Dig you sure you have enabled SATA support in kernel.
I suggest using libata driver in SCSI section. (It faster at least 10%).

At least, LiveCD can boot and remount your root (do mount same as when you installing gentoo, chroot and then go check kernel again).

dish,

Your fstab is wrong. You have raid devices so the entries are
/dev/mdN,
/dev/hdX2 or /dev/sdY1, only refer to part of the raid.
Likewise, your kernel line should say root=/dev/md<something>

NeddySeagoon,
Thanx, it worked

Could you tell us the output from

fdisk -l

then you'd know for sure where the drive is if gentoo/linux can see it ;-)
