Netraid Array Expansion taking very long time

[Bas Woudsma]

I have a test server Windows 2003 advanced server
I have added two 72 gig drives to a 6 disk array raid5. Only 1 gig of data on there just to test. It took more then 9 hours to complete the expantion. (I left to let it run during the night so was unable to time exactly) So somewhere between 9 and 24 hours to expand. Then while the background parity initialization was still running I used diskpart.exe to add the space to the array (remember to do the expantion twice in ACU to really add the space to the logical volume. Second time is instant) I have basic disks configured. So using diskpart.exe while parity initialization is running is working on my server. G3 server DL380 with 5300 controller card and MSA50 attached.
