Thanks, David. Maybe f17 installer is easier for me. I never install dualboot Linux on one hard disk. I always test such things on my slc usb3.0. Back to the title. As I used yesterday, f18 anaconda partitioning interface just made me more confused. I'll try f17 anaconda to see if things can go along. And, fedoraforum suggest me using ext4 instead of lvm.

I was hoping someone else who actually remembered how to do this would respond to your question. That hasn't happened so I'll give it my best shot. I run Fedora from a 400GB external hard disk for my laptop (long story). I more or less divide the disk between the current Fedora release and the previous release. That way, by the time the previous release is no longer supported, there is a new release to try and the current release is relatively stable. So, currently, I have FC 18 on one partition set and FC 17 on the other. It took several tries to find where the option is hidden but there is a button on option of some kind on the partition screen that allows you to install over existing partitions. Unfortunately, I don't remember exactly where it is or the label. I just remember that it wasn't at all obvious. Restart your installation. Poke around on the partitioning screen. There is a well hidden option for installing to existing partitions. Once you find that, you get the familiar installer partition tool for assigning partitions to mount points and the option to format the partition or not. Cheers, Dave

When you have your fc17 installed and booted, only then you make the rest bootable by asking grub2 to find it: grub2-mkconfig -o /boot/grub2/grub.cfg That should find lots of stuff for you. -- Bill Davidsen <davidsen(a)tmr.com&gt; "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot

Allegedly, on or about 01 March 2013, Craig White sent: Yes, that kind of thing was what I meant by spanning (not sure if it's meant to be the term, or just how it's been described in the past). I have wondered, that if you're already doing RAID, can it provide the same ability? I'm guessing that if you wanted to increase the size of a RAID, it probably entails adding more than one drive at a time.
