Win2K - Basic to Dynamic - Then Extend - ??

Hi - So I have a Compaq ML350 with a RAID 5 config (3) 18.2G drives.  Setup in Windows as a (basic) single disk with 3 partitions (4G, 4G and 25G - respectively).

The 25g partition has Exchange - and we are running out of space - fast!

I purchased another drive (18.2) threw it in the server and realized the RAID card will not support extending arrays :(

After some research, I see that it is possible to upgrade the basic volume to dynamic, but that "...you cannot extend a simple or extended volume that was upgraded from basic to dynamic..."

I'm sure this is true - just hoping that I don't have to blow away the server and start from scratch.

Any thoughts - anyone run into this before?

I'm not aware of any third party products that will extend  your array, but they might exist. Even if they do you probably wouldn't want to spend the cash on such a product. I can confirm that you can not do it within Windows. A disc must be converted to dynamic BEFORE you create any volumes. Any existing volumes or partitions before the conversion are locked. Hopefully one of the experts here will prove me wrong, but I would say you need to reinstall. Sorry.

Try using "diskpart" from the command line. It is in the Resource Kit. No guarantees, but it worked for me

Umm...rhrowson,  I never thought of using diskpart. That just might work in this situation. I always forget to check the resource kit before looking at 3rd party tools.

I never ended up using diskpar - but I read quite a bit about it.  It may have done what I needed, but the array controller (Smart Array 221) would not expand the array..  So I had to reformat the whole thing :(

Thanks anyway..
