 Posted: Thu Oct 12, 2006 9:51 am Post subject: Migrating Gentoo to a SATA HD |
 |
|
Hello everybody
My Gentoo installation is currently on a 20GB IDE HD. I want to transfer my installation to a new SATA HD I bought. Do I need to compile SATA support in the kernel in order for this to work? I also use GRUB boot manager. Is GRUB compatible with SATA HD?
thx, in advance

Yes and you have to adjust fstab as well as grub.conf and of course you need to rewrite MBR.
+ what I forgot to mention

ok. I found this page in the Gentoo Wiki http://gentoo-wiki.com/HARDWARE_SATA. But what changes do I need to make to fstab and grub.conf in order to get it to work with a SATA HD. This is how I have my fstab now :
| Code: |
/dev/hda1 /boot ext2 noauto,noatime $
/dev/hda2 none swap sw $
/dev/hda3 / ext3 noatime $
/dev/cdroms/cdrom0 /mnt/cdrom subfs fs=cdfss,rw $
/dev/cdroms/cdrom1 /mnt/dvd subfs fs=cdfss,ro $
none /proc proc defaults $
none /dev/shm tmpfs defaults $
/dev/fd0 /mnt/floppy subfs noauto $
|
and my grub.conf
| Code: |
default 0
timeout 10
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.17-r8
root (hd0,0)
kernel /kernel-2.6.17-gentoo-r8 root=/dev/hda3 video=vesafb:ywrap,mtrr,1024x768$
initrd=(hd0,0)/splash-livecd-2005.1-1024x768

Wait. I think
| Code: | | initrd=(hd0,0)/splash-livecd-2005.1-1024x768 |
Should be
| Code: | | initrd=(sd0,0)/splash-livecd-2005.1-1024x768 |
Not quite sure though.

no, hd in grub just means HardDrive, regardless of drive interface.
it is pretty easy to move your installation to a new drive with `dd`, if you need help with this, let me know  |

Sorry for reviving this post, but I have the same "problem", I want to move all my HD content to a new SATA drive.
My actual situation is: Gentoo on IDE0 master, windows on IDE0 slave. The future situation is: Gentoo on SATA, windows on IDE0 master.
Apart for changing /etc/fstab, how I must change grub? I don't understand that hd vs. sd stuff, because grub must know in which HD is the stuff installed.
And what about the dd command? My idea was doing a cp -a after partitioning the new HD. Is better/worst/impossible doing this? Keep in mind that the partitions of the new HD will have different size.
Thanks for your help.
Edit: I forgot to say that I want to change filesystem also, so I suposse that dd won't work.

| My grub.conf didn`t require any alteration. I only altered /etc/fstab as shown in the posts above. It worked smoothly except for the fact that the kernel complains that it can`t find /dev/tty1 during boot. |
