ext3 filesystem getting mounted as ext2?

[ewildgoose]

I think my ext3 root filesystem is getting mounted as ext2. I notice the following message in the boot log:

EXT2-fs warning (device ide0(3,5)): ext2_read_super: mounting ext3
filesystem as ext2

However, it is not clear because running "mount" shows the root filesystem listed as ext3. I seem to remember reading that the output from mount was not neccessarily accurate for this case though?

/etc/fstab lists this as ext3. ext2tune -j says that there is already a journal present.

The only thing (which has just occured to me) is to check whether I am compiling ext3 as a module. What are the implications of this anyway? If I have done this do I just need to put the module in modules.autoload or is it easiest to just compile ext3 into the kernel (since it is always needed).

Thanks

You should put ext3-support in the kernel.

The kernel cannot mount the a partition without the module, and cannot load a module from a partition he cannot mount. It's the chicken-egg problem. You can solve this with an initial ramdisk (I think).

It's easier to put those things into the kernel.

It only just occured to me as a possibility. However, I don't know if that is in fact the default when ticking kernel options? If so, then probably this is what I did...
