    Just installed WHS 2011 on a four 1 TB drive raid 5 array (2.72 TB).  The installer set up a 60 gig drive c: partition and a  1.95 TB drive d: partition.  ....BUT....  745 gig of the array was left unallocated?

    Is this typical/normal ?

    Yes, this is normal, I assume the scripted installation is not allowing larger sizes for the system disk than the 2 TB of a physical disk in the common MBR scenario. (UEFI, which supports booting from larger disks, is still not widely supported on hardware level.) Since Server backup is also limited to a total size of 2 TB, it makes also sense in this context.

    You should be able to use diskpart to extend the volume by performing following steps:

    Login locally or via Remote Desktop on your home server.

    In Start menu Search dialog type cmd, right click the found result and select Run as Administrator.

    type following commands, each ending with Enter:

    diskpart

    select volume D:

    extend

    This should extend the  selected volume by the free subsequent space.

    Best greetings from Germany

    Would it be better to remove one of the drives from the current array and set it up as a 3 drive array or a 3 drive plus hot spare?

    OR

    To create a 3rd partition and use that for "basic" storage, external to the backup features (maybe mapping the my docs, my pic, etc to this 3rd partition)?

    This is a clean install on new hardware and I have only run one workstation through the client backup process to get a feel for what is where and how it functions.  I can easily reset the array and reinstall the OS or create a 3rd partition without too much muss or fuss at the present time.

    I'm a little disappointed to find a "glass ceiling" but glad to know about it rather than find out later I have made a critical error by trusting it to hande "too much data"
