How to get ext4 on Meego?

[Aaghaz]

One of friend told me about Meego and I have installed the same on my mobile. Well I am really satisfied with the look and feel of this particular operating system. Well now I am here because many of you might be using Meego itself also you might know the solution for the particular query which I am going to post in this thread. Well the question is very simple. I want to get ext4 file system on Meego which I have installed. So please provide me any useful information which I can apply in order to meet my requirement. Any suggestions will be highly appreciated. I am waiting for your prompt reply. Thanks a lot in advance.

Well I really don’t which steps should be taken to get ext4 on your Meego. However I know something about ext4 which would be helpful to improve your knowledge. Well ext4 simply stand for fourth extended filesystem. Simply it’s a journaling file system which is used for Linux and it is developed after the success of ext3 file system. Journaling file system implies that it’s a file system which keeps record of modification made in to the journal before it’s applying on the main file system. Well in case of either system crash or power failure this kind of file system helps to get back online rather than to being corrupted

I am posting following steps which you can use to get ext4 on your Meego. You have to configure the Meego by using the following. You have to modify the following file.

EXTRAVERSION=.5

To

EXTRAVERSION=.5-24.1

Now you have to copy official config by using the following command.

cp /boot/config-2.6.33.5.24-1 .config
make oldconfig

Next step is to enable ext4 in the file system as module by using the following one.

make menuconfig

Now prepare for compilation

make prepare
make modules_prepare

Now you have to compile the module by using the following one

make M=fs/jbd2
make M=fs/ext4

Now it is ready to use and see whether it is working or not.

insmod fs/jbd2/jbd2.ko
insmod fs/ext4/ext4.ko

If it is correct then install the same

mkdir -p /lib/modules/2.6.33.5-24.1-netbook/kernel/fs/jbd2
mkdir -p /lib/modules/2.6.33.5-24.1-netbook/kernel/fs/ext4
cp fs/jbd2/jbd2.ko /lib/modules/2.6.33.5-24.1-netbook/kernel/fs/jbd2/
cp fs/ext4/ext4.ko /lib/modules/2.6.33.5-24.1-netbook/kernel/fs/ext4/
depmod

Now you can load the module by using the following command.

modprobe ext4

Well if you are having any query regarding this particular solution then feel free to ask the same. I am hoping that it will help to meet your requirement.

Well the solution which you have provided above really worked till the loading the kernel. However I have solved the problem by using loading the kernel manually. Well I have used the following command in order to load the kernel.

modprobe ext4

Then I have made the file /etc/modules.conf where I have put the following one.

jbd2
ext4

But it did not help me at all. Also I am unable to load the module by using filemanager. Please let me know any suggestion with you to fix the problem.

Well looking at the post which you have posted prior I can give you answer regarding the first question. However I don’t have any solution for remaining two questions. Well you have to edit the file which is located at /etc/rc.local location. You have to enter following line of code.

modprobe ext4

You have to execute the file at the time of boot. You can also use the Mount command in order to solve the matter.
