grub ext4 recognition

Hi everybody,

I just have installed slitax 5 on a ext4 partition, /dev/sda1 It uses Grub, but not Grub2. Grub2 I could install, though. But my problem is that I have another installation on /dev/sda2 with Grub2, also on ext4. Now mz (Slitaz-) grub on /dev/sda1 does not recognize this one. With blkid it is recognized:

/dev/sda2: UUID="f1e9a3f2-d8fd-4859-b660-e15918d98ba0" TYPE="ext4" PARTUUID="e8753a1d-02"

What to do to boot that with (Slitaz-) Grub?

Re: grub ext4 recognition

I found that there had been a tazpkg for ext4-support, but for Slitaz 3: linux-ext4

So the question is how to support ext4 now? There is apparently no kernel module for it, at least I could not find one.

ext4 is no problem for SliTaz 5

Re: grub ext4 recognition

I have another problem. I first installed q4os with Grub2 on /dev/sda2. Had a Grub2-boot menü. Then I formated /dev/sda1 as ext4 and I installed Slitaz 5 on it. It automatically placed its „normal“ old Grub in the MBR but only with 1 menü element: Slitaz. Manually I cannot boot q4os then. When I use

root (hd0,1)

Kernel /boot/vmlinuz... etc

I only get the message that the kernel cannot be recognized. So I must either find a way to change to (Slitaz 5) Grub2 and adapt it - or I have to install q4os on /dev/sda2 again.

Re: grub ext4 recognition

drum hab ich Dir ja den link geschickt....

ich finde nirgends was zu q4os und grub nur grub2 - am besten q4os neu installieren und slitaz zu grub2 hinzufügen

Grub2

menuentry "SliTaz GNU/Linux (cooking)" {

   set root='hd0,1'

   linux /boot/vmlinuz-3.2.98-slitaz root=/dev/sda1

}

Re: grub ext4 recognition

The next day it worked. Most likely the file stage2 from my Slitaz 5-LiveCd was corrupted. Being a layman this might be a wrong explanation, so be careful! ;-)
