I am using entire disks.
147GB U320 disks 8 MB Cache

I want to use 6 disks rather than 4.

Is there a limit it seems to be

4 or 8 whole disks...

I need to do 2 or 3 or 4 or 5 or 6... is this
possible?

Bad idea, why don't you want to at last put a partition table on it, with one big partition, that uses the whole disk ... or is this what you had in mind?

I'm using 1, 2, 4, 6, 8, 12 disks partially with hard- and soft-raid with LVM. no problems.

So, what again was your question?

There is no minimal number of disks/physical volumes for LVM. IIRC a Volume Group can not be bigger than about 2T, but that seams to be a kernel limmit and you will not each it with 1 - 6 of this "little" disks. :-)

And it might be 3, 5, 7, 9, 10, 11 as well ;-)
