Well, I thought I would close the thread with a follow-up on how it went and
what I ultimately went with. I ended up expanding the extended partition to
encompass the remainder of the disk. I then created 2 ext4 partitions, a 6 gig
for private data that can be mounted for use then unmounted and the remainder as
a big data drive. Both are dmraid mirrored partitions.

The current mount options are:

/dev/mapper/nvidia_ecaejfdip12 /data ext4 defaults 0 1
/dev/mapper/nvidia_ecaejfdip11 /home/david/pvt ext4 defaults 0 1

are you guys saying I should add 'auto_da_alloc' as an option for all ext4
partitions?
