[SOLVED] Mounting ext4 partition

rusyd · 08-21-2010, 09:50 PM

Hi, I'm still new to Gentoo
I have compiled my kernel with ext4 support and done instructions in wiki but I'm still unable to mount my ext4 partition.

The output says: "Unknown fs type ext4"

Any idea how to solve my problem?
Thanks.

Did you install e2fsprogs:

Code:

$ cd /var/db/pkg/ && ls -d */* | grep e2fsprogs

Re-check also if your kernel support ext4:

Code:

$ grep -i ext4 /usr/src/linux-`uname -r`/.config

Have you compiled it as module. If so then first as root enter the command "modprobe ext4". Then try mounting it.

CONFIG_EXT4_FS is not set

This is my fault.
I forgot to save my kernel configuration to .config so the kernel was compiled with default configuration and doesn't support ext4.
I have already recompiled my kernel again and now I can mount ext4 partition perfectly.

Thank you very much
