The 240 error can happen:
a) If you are trying to mount the drive in an EXT4 on an EXT2 partition
(journaling is disabled).
b) If you have mounted in EXT4 when using grub.
*c)* If you have a ext4 root and don’t use grub2, you can obtain this
error:
EXT3-fs: sda1: couldn’t mount because of unsupported optional features (240)
Add "*rootfstype=ext4*" to the kernel line* or at the grub> line when
specifying the initrd?
**ARE you CERTAIN you have ext4 and not ext2?
You can "fdisk -l" to see a list of disks and types.**
*
Of course, there also is:
d) Your drive journal is toast as your fsck failed.
I suggest you boot into either recovery mode or LiveDistro/Knoppix and
manually work on the drive or:
0) Boot into recovery mode and follow these instructions.
https://help.ubuntu.com/community/LiveCdRecovery
if not successful:
0) Move off or backup your data.
1) Rebuild with new distro version following recovery recommendations:
I can drop an Ubuntu Live and a knoppix tool distro into the mail for you
today? What is your distro version exactly, please and upgrade choice?
Contact me offline with your address?
