I keep ubuntu 9.04 in my nand as a backup OS and my main OS is Debian squeeze installed in an ext4 partition on an USB disk.
But when I want to make somes maintenance actions on Squeeze, Ubuntu won't mount /dev/sda2 in rw mode because ext4 format is not fully supported.
How I can resolve this ??
I have 2.6.30 kernel for ubuntu and upgrade are ok.
