You don't see any "filesystem" or, more correctly, partition in your

output because you have apparently created your filesystem on the

device (hey, I didn't know one could do that!). 

That, actually, is the norm. It is NOT normal to partition a raid array

it IS normal for several reasons

* you may end with a replacement disk which is subtle
   smaller and hence you normally make the partition

And what does that have to do with the price of tea in China? 
Partitioning your array doesn't have any effect on whether or not said 
array uses the whole disk or not.

And putting a partition table in your array does exactly what to help that?

Which is why I partition my disk. I use one raid for the OS, and another 
for my data.

but than "fdisk -l" shows partitions - what the hell.....
that above you responded to has no partitions but the whole drive for 
the RAID
