[gentoo-user] Gentoo from ext3 to ext4

[gentoo-user] Gentoo from ext3 to ext4

[reQuiem23]

Hi all,

i just had the idea to make a new ext4 partition (via mkfs.ext4) and copy
(cp) my whole root-dir into that new partition, change the /etc/fstab, add
an entry to the grub.conf and booting into that new partition. My /boot is
on a separate ext3 partition, so this is not a problem. The kernel i use is
gentoo-sources 2.6.28-r1 with ext4-support enabled. However, when i want to
boot into my new system, the system starts, even the uvesafb starts, but
than the booting process stops with a message like "tty starting" and the
system reboots.

I removed all the files in /proc /dev and /sys, so probably this could be
the cause of the problem. Or does anyone have an idea what could be the
problematic factor here? unfortunately i can't provide any logging
information because i can't get to a working shell :(

Greetings,
Niklas

yeah, but my /boot is still ext3 and grub IS actually loading the system, it
even runs uvesafb. or is grub even incompatible with ext4 root-filesystems?
i thought this was entirely handled by the kernel.

I have ext4 root filesystem on 2 machines running gentoo & grub and
it's working fine. Don't give up :)

Grub is not incompatible with ext4 root filesystems as long as you, as
you do, have a separate /boot partition with a 'supported' format. It
works fine here with ext2 /boot and ext4 / - but I converted this using
tune2fs from etx3 rather than creating a new etx4 root (but I did create
a new ext4 /home on a different drive)

What you describe is pretty much my setup. I read that converting the FS
with tune2fs would not affect the storage of already existing files so i
thought it would be better to copy it all over. I also don't have another
64bit system with 2.6.28 kernel on my PC, so I tried it this way.

Don't know if it is related, but for me I had to put rootfstype=ext4
on the kernel commandline. Also make sure you're using
sys-boot/grub-0.97-r9, I know it has ext4 support.

I actually have that parameter on the kernel command line. I'll check my
grub version, though, thank you.

Be sure to re-install grub to MBR as well. Just emerging it won't be
good enough.

Make sure you have /dev/console and /dev/null in place ... it's needed
*before* /dev is mounted over with tmpfs for udev.

You can copy those from where ever, CD, old install, it shouldn't
matter.  They just need to be there.

Yeah, you probably shouldn't have done that.  There are 'skeleton'
copies of /dev/ files in your root partition before udev kicks in and
those files are needed by the boot process (e.g. /dev/console).

What I recommend doing is:
      * boot into a livecd/usbstick
      * mount your root partition (ro) somewhere (e.g. /tmp/root
      * mount your empty destination partition somewhere
        (e.g. /tmp/newroot)
      * copy the files over to the new ext4 partition in whatever manner
      * reconfigure new fstab, grub.conf, etc and reboot.

For livecd/usb I always use RipLinux.  The latest version supports ext4
and has both 32- and 64-bit kernels.

I did it exactly the way you recommended, but i still get an error, even
though it's another one than before:

Kernel: Unable to open an initial console.
Kernel panic - not syncing: No init found.  Try passing init= option to
kernel.

An idea?

I had a similar problem with my initial LiveCD install. Do you just  
boot directly from the gzipped kernel image or use initramfs?

As expected, it was not a good idea to try and boot from an empty root
partition :D now it all works, I'm writing this from ext4, thanks to all of
