I seem to be just getting more and more lost. I ran mkinitrd and over-wrote the existing .img file in /boot/ but it didn't seem to make a difference. Running "lsmod" confirms that ext3 is not loading, and "modprobe ext3" seems to work fine so it's not an issue with an uncompiled module. I don't understand how this stuff works in any way; any chance I can impose on you for a slightly more detailed explanation on ensuring ext3 loads at boot? Or if I need to RTFM some recommended reading would be appreciated. Apologies and thanks very much for all the help you've offered... ----- Original Message ----- > Probably because you are using an initrd with ext3 as a module and not > compiled into the kernel. Try "mkinitrd" if that is the case, or just > compile ext3 into the kernel.
