well, I don't have to have one giant disk, but I have to have one big disk from the RAID card, after that I can, and I was trying to, partition the disk, but not fdisk nor parted could get the last cylinders of that big device
so I hade to partition it in in the RAID setup.

The problem is that if I don't have only one big disk created in the RAID I can't add more disks to it, at least as I've understood it, but I think I'm gonna mail support and ask just to be sure.

In the picture below I partitoned the disks in 3 parts
One is 1Tbytes and the other 2 equally 768Gb.

When I'm suppoed to add more disks I have to "mark" on the the RAID array and then add the disk, but since the arrays are NOT equal to the HDD size of 500Gb I can't add the disk, but as I said, I'm gonna email support and ask just in case. But my tests of the other array of disks point to the fact that I am correct in my assumption

Can I ask you what the make/model is of your RAID controller? I see you are using RAID5 and you have 6 500GB drives attached. If I understand your issue you want to be able to add more disks at some point in the future and expand the size of the logical volume on your controller at that time. You claim you can do this if you create one large logical volume but not two smaller logical volumes. Do I have this correct? I would like to do some research on the issue if I can get your make/model.

Will it only allow you to create a single RAID set? That would be odd. For example with your 6 disks you should be able to create 2 stripe sets of 3 disks each and give you two logical disks of 1.5TB each (you don't have fault tolerance of course but this is just an example). Or with 2 more disks you could have 2 RAID5 logical disks at 1.5TB each. With 4 more disks you could have 2 2TB logical volumes. It would seem odd if you can't do that.

The controller is a HighPoint RocketRaid 2340. http://www.highpoint-tech.com/USA/rr2340.htm

And yes you understood me correct :)
I have more than one RAID set, just created another 800Gb RAID 5 of 5 200Gb disks.

What I was hoping to accomplish is that if I add more disks all the partitions of that array will get bigger in size.

It looks like you would have been better off buying a lot more smaller disks so you could have created more smaller RAID sets. It will be interesting to hear if the manufacturer has any suggestions for you.
