Adding unallocated space to an existing partition

Last Modified: 2012-05-06
I have an HP Proliant DL380 running a RAID 5 with 147GB drives (2-data, 1-parity and 1-spare). I just added 2 more drives and was able to add the drives to the existing logical drive using the HP Array Configuration Utility. Windows recognizes and shows all of the new drive space as unallocated.  What is the best (and easiest method) of adding the unallocated drivespace to the existing partition C: without losing the existing data and while unit remains in production. The server is in a file server role for about 150 employees though I estimate only about 40-50 maybe accessing their network share at any given moment.  Live State Recovery is run daily backing up data to a backup server. Weekend implementation is possible to minimize I/O from users. Any suggestions for combining the Primary (and only) partition with the unallocated space?

I would say use Partition Magic for the primary partition.
It's been a while since I've used it, but I'm pretty sure I've used this on Windows Server 2003 to resize a primary partition:

AFAIK nothing can resize C: on the fly. Should have set it up as 2 seperate logical disks, then you could have used diskpart to resize live. You can still use diskpart of course but you will have to use it from a CD since it cannot resize the boot partition. Also gparted CD above will resize offline only (but does the job fine).
