Hmm, odd, ext4 is supposed to be supported in klibc's fstype which should obviate the need for this.

Works like a charm here too. Brought up a second system successfully with ext4. The first try (error 24) showed up to be a misconfiguration in the grub's menu.lst and is now up and running as well.

An even simpler solution is to append rootfstype=ext4 to kopt in /boot/grub/menu.list, eg. # kopt=root=UUID=24c707be-c824-4781-89bd-25ed9dba54f8 ro rootfstype=ext4 Then just run sudo update-grub.

[Bug 309762] Re: initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image)
Just to confirm, the custom_mount_ext4 script is only needed in local- bottom. Also, the `modprobe ext4` is not needed, since it's compiled into the kernel now. However, it's probably wise to using `-t ext4` as the mount option. #! /bin/sh mount -t ext4 /dev/sda1 /root mount -t ext4 /dev/disk/by-uuid/.. /root Works like a charm for me. -- initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image) https://bugs.launchpad.net/bugs/309762 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Confirm this bug. I've tried the break=mount option too without success. I can mount an ext3 volume but still not an ext4. $ mount /dev/sda1 /root results in (obvious as ext3 defaults): EXT3-fs: sda1: couldn't mount because of unsupported optional features (40) mounting /dev/sda1 on /root failed: Invalid argument $ mount /dev/sda1 -t ext4 /root results in (sda1 is ext4): mounting /dev/sda1 on /root failed: No such device In my case I made a conversion ext3 to ext4 using this guide http://kernelnewbies.org/Ext4 that is, $ tune2fs -O extents,uninit_bg,dir_index /dev/sda1 $ fsck -pf /dev/sda1 uname -r 2.6.28-3-generic So I guess it's up to what ext4 features you activate that makes the ext4 device mountable or not in the initramfs shell. However, I can boot up another Jaunty system an mount this sda1 device there with success so the device itself is ok. -- initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image) https://bugs.launchpad.net/bugs/309762 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

see Bug #309758 about adding the ext4 module to your initramfs image first. I gave some workarounds in there.. Basically, you have to get ext4 and it's dependent modules in the initramfs image, and you have to get the scripts to 'modprobe ext4' before you can mount the partition. -- initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image) https://bugs.launchpad.net/bugs/309762 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 309762] Re: initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image)
Sorry, but that update of the initramfs image made my sda1 unbootable. Error 24: Attempt to access block outside partition. What I did was, I chrooted the device and updated the initramfs image acc to bug #309758. Then at reboot error 24 was issued. I fscked the device with no error! It's still mountable from another system. So one way here might be (or is a must) to update the image before the ext3 to ext4 conversion.

[Bug 309762] Re: initramfs fails to mount ext4 root partition or provide user intervention (even when ext4 module is available in the image)
The problem is that fstype doesn't detect a ext4 filesystem. It detects
it as ext3, and tries to mount the rootfs with mount -t ext3..., which
fails because ext3 can't mount a ext4 filesystem.
The problem is in scripts/local:
get_fstype ()
{
local FS FSTYPE FSSIZE RET
FS=${1}
# vol_id has a more complete list of file systems,
# but fstype is more robust
eval $(fstype ${FS} 2 /dev/null)
fstype pass ext3 as filesystem there.
It turns out that the unreliable vol_id detects the ext4 properly,
while fstype does not...
