Hey guys,

I am getting the error that is in my topic, and I have no clue why. I wish it would tell my why my root filesystem could not be mounted, maybe even give me a little hint.

Can anyone give me some guidance as to figuring out why it can't be mounted?

It drops me to a read-only filesystem, then i do "mount -o remount rw /" and it remounts it as rw

however, "mount" shows / as being of type "rootfs"

my root is /dev/sda6 and is of type ext3, i have this specified in the /etc/fstab and ext3 support is built into my kernel.

Thanks!
George

one more thing... during boot right before it gets into the run level stuff, it says:
Code:

VFS: mounted root (ext2 filesystem) as read-only


why might it think root is ext2?

Have you tried in unmounted state to check the filesystem, especially to rebuild the journal (as ext3 is just ext2 with a journal IIRC)?

ok maybe i didn't do it wrong in the first place

i did:
Code:

mkfs.ext3 /dev/sda6


then i tried to mount it with:
[code]
mount /dev/sda6 /mnt/gentoo
[code]
and I get this warning, which ends up mounting it as ext2:
[code]
EXT2=fs warning (device sda6): ext2_fill_super: mounting ext3 filesystem as ext2
[/code]

So it does mount it as ext2... so then I try to mount it specifying the filesystem with an -t ext3 and it mounts it as ext3

am i missing something here?
