Hi,

I spend all my day to try to figure how to replace my IDE drive with my brand new Sata 320GB. I'm a kind of Linux newbie.

I take Gparted (Great free application) to copy the three partitions. But when i rebooted with the new SATA drive the nightmare begin. No boot disk...

I looked here on the forum and one the knoppmyth wiki. I try few solutions without success:
Edit Lilo, modify fstab and lilo.conf, erase mbr, remake lilo, change hda to sda, ... After a lot of tries the system begin to load on my system with the SATA drive and suddenly "Kernel Panic Error" just before the welcome screen. I checked agin on the forum for kernel panic error without success. I'm stuck there and i'm a little bit deseparated.

Can you point me to the right detailed informations.

Thanks and excuse me for my poor english

Don't think you can migrate a live system like that. Run the backup script on the old drive then do a clean install on the sata drive using R5E50 cuz it works with SATA hard drives. You can handpick files to put from the old drive back on the new drive like /myth/tv/*

Then copy over the /myth/backup/* to the new drive and run the restore script.

I did this successfulyl recently. To be real honest, if you don't have a fairly proficient knowledge in Linux, you're in for a hard road.

But I'll throw you the best bone I can.

BACKUP BACKUP BACKUP NOW BEFORE YOU GO ANY FURTHER, YOU BEEN FREAKIN WARNED. had to get that out of the way.

My /myth partition is XFS which supports online expansion. EXT3 does as well, I'll assume you're using ext3 and this it a mythtv box you're trying to upgrade.

I'm assuming that the partition that you want to grow is the last one (i.e /dev/hda3).

do a fdisk -l as root and make sure, here's mine for example.

dev/sda1 * 1 7 56227 83 Linux
/dev/sda2 8 142 1084387+ 82 Linux swap / Solaris
/dev/sda3 143 38913 311428057+ 83 Linux

Notice how sda3 is the last partition and is the big boy?


What I did:

1. You'll need to use a Linux boot CD and do the copy with both drives unmounted, I used Knoppix 5.0.
2. Once in you boot cd, as root, do this:

type mount and press enter, do you see any of your /dev/hdX or /dev/sdX partitions mounted as read only? if you do unmount them all with a:

umount /dev/sdX

or

umount /dev/hdX (X being the partition number)

Now that it's unmounted its time to clone the hda drive to the sda drive, as root:

dd if=/dev/hda of=/dev/sda conv=noerror,sync bs=4k

be prepeared to wait a while, I copied a 160 Gig to a 320 Gig and it took right at 55 minutes. Make sure you tune your drives with hdparm and enable DMA or you'll be waiting half the night..

3. when finished, reboot and REMOVE your /dev/hda drive as it's no longer needed. The hda drive is completely intact, keep it safe as it's your fallback.

4. boot knoppix again and become root at the command line

5. use parted to expand the ext3 partition, reboot

6. boot knoppix again and become root at command line

7. make a mount point for your mythtv data partition, the one with /usr /bin /sbin on it , it should be /dev/sda1 now. If knoppmyth already mounted it, unmount it as it's mounted read only, you dont want that.

umount /dev/sda1

mkdir /mnt/sda1 (if one isnt already there)

mount /dev/sda1 /mnt/sda1

cd /mnt/sda1

do an ls -la, you should be in the root of you mythtv os partiton.

do a "chroot ."

now edit your /etc/fstab, your /etc/mtab (jusr for kicks) and your /etc/lilo.conf to reflect your new sdaX instead of your hdaX.

rerun lilo: lilo -b /dev/sda
sync your disks: sync
exit out of your chroot: exit
go back to the knoopix root and unmount the SDA drive:
cd /
umount /mnt/sda1

reboot and you should be good to go.

Or, you coudl do what snet suggested.

I added few things that I forgot to my post above.

Have questions? ask!
