I think you jumped over some very import information here.
/dev/da0p6 would seem to indicate that when you allocated the da0 disk 
drive you created partitions on the disk drive which you planed to use 
to segregate your jails by partition. Is that a correct interpretation?

If you showed the da0 disk layout with the partition directory trees and 
the jail.conf definition statements for the example jail and used the 
real fstab statements containing the real paths then it would become 
easier to see the complete picture of how things relate to each other.
