Mounting an ext4 drive on Intrepid

[fontenot_1031]

Hi, I'm still on Intrepid because I want to use the proprietary drivers for my graphics card which was dropped after Intrepid.
Anyway I have an ext4 partition on my computer from my last install and I want to be able to mount it on Intrepid without having to move all the data off of it and formatting it to ext3. What are my options?

Locate the harddrive on the disc:

df -h

Mount your harddrive partition to a mountpoint on the disc (where sda would be changed to your choice):

mount -t ext3 /dev/[sda] /mnt/

Change to the mounted directory:

cd /mnt

where you can copy the files from the partition you need to keep.

david@hpdv5000:~$ sudo mount -t ext3 /dev/sda2 /mnt/datadisk
mount: wrong fs type, bad option, bad superblock on /dev/sda2

Would I have a hardtime building a new kernel with ext4 support?

You can do it. I had to do it just now, because I'm backing up an old server onto an external disk and the only external disks I have are ext4.

The trick to it I found is here: mounting ext4 on intrepid. The key command to look at there is using the tune2fs -E test_fs /dev/sd__ to enable experimental FS mods.

I have no idea how reliable this is. I hope it works well enough that I can get the files off securely, that's all.
