Not exactly. It depends on whether or not you enabled extents when using it as ext4.

poc


I am not that technically proficient. The ext4 is for Ubuntu 9.04; Fedora 10 has ext3 and used to give console error messages about being unable to umount the ext4 partitions during shutdown. I had to do a reset as the PC stalled at that point.

Presently, I have added the 'noauto' option to Fedora 10's fstab file so that the ext4 partitions are not mounted. This stopped the error messages and enabled proper shutdown.
