From: mess-mate on 20 Jun 2010 12:00 i've squeeze and lenny installed and squeeze as a production system now. Recently installed grub2 (1.98) on squeeze on the MBR of hd0. Evereting goes well but i can't boot lenny. The lenny file system partitions are for /boot ext3 and all others ext4. When i try to boot lenny i have this error message: exit_fill_super:extents feature note enabled this filesystem, use tunefs So can't mount /dev on /root/dev, etc..... grub.cfg: ..../... menuentry "Lenny, kernel 2.6.28_mm01 (on /dev/sdc6)" { insmod ext2 set root='(hd2,4)' search --no-floppy --fs-uuid --set f26b56c1-4550-4815-b7bf-e5f114c6f9e4 linux /vmlinuz-2.6.28 root=/dev/sdc6 rootfstype=ext4 ro quiet vga=788 initrd /initrd.img-2.6.28 ...../... this kernel is a self-compiled with of course ext4 enabled on it and had never problems to boot before i installed grub2. Seems ext4 not supported by grub2 ? any help would be very appreciated. mess-mate

I know and googled about it before. There are no error messages when i do an update-grub. This is maybe the most important error message i can given on the boot: exit_fill_super:extents feature note enabled this filesystem, use tunefs set root='(hd2,4)' or set root='(hd2,5)' (count from 0 or 1) didn't change anything. The root is on hd0 and partition 5 = first logical ext4 and /boot is a separated ext3 partition. In the past grub legacy booted without any problem with lenny. BR |
