Maybe create a /data path, then:
Code:
mkdir /virtual
mount -t ext4 /dev/sda11 /virtual
Your /etc/fstab would look like:
Code:
/dev/sda11 /virtual ext4 defaults 0 <number>
...where <number> is the sequence number by which fsck tests filesystems. I think I got all that right, but stare at it with a jaundiced eye for a bit to make sure ; )
