Pick your reason. > 1) ext3 is identified as ext2 on bootup. > 2) There is no fallback to ext3 if ext2 is not found. Doesn't make sense. The kernel just tries all registered filesystems for the rootfs until one clames it. It means you either: - don't actually have ext3 in the kernel or - the filesystems actually is ext2 and not ext3 Try calling debugfs /dev/$ROOTDEVICE and then typing features, what does it say? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
