New Setup, Non-standard Landing Zone Location

[t0bbe]

I have currently an LVM setup that I want to scrap and start over with a 4 disk Greyhole setup.

The problem I have is that I'm using a 8GB SD card for my system partition, so I can't use that for the landing zone.
Also, I'm running Crashplan and have backed up a lot of data from my current shares at /var/hda/files/sharename, and I don't want to have to start over again uploading all that data to the Crashplan servers (very slow), so I would like my new Greyhole shares to still look like /var/hda/files/sharename.

How do I set up the Greyhole storage pool for this to work?
Do I just mount one of my disks as /var/hda/files and the rest as /var/hda/files/drives/ or similar, would this automatically set the landing zone to use the disk mounted as /var/hda/files ?

Also, what's the best partition type to use, ext4?

Thanks!

EDIT:
I found another forum thread that seems to answer my question,

I'll give it a try mounting one of the drives as /var/hda/files and the rest under /var/hda/files/drives/driveX

It's a good idea to have your Landing Zone (/hda/files) mount on the largest storage drive. That way large transfers will not fill up a drive before you run a "greyhole -f"
