Spanned volume limit reached

Question

_{Friday, October 16, 2015 10:53 PM}

I have inherited a virtual 2012 Server with a large spanned volume. The spanned volume is currently 55TB and contains 32 separate virtual disks. Some of the disks at 2TB and some are only 1TB. There appears to be a 32 disk limit to spanned volumes. I've tried to expand one of the 1TB disk to 2TB but when I try to expand it considers that space a separate disk. They need to expand the volume and I'm trying to find a way to do that for them. Can anyone offer a suggestions? I would love to create a single SAN LUN and just map to it directly and create a single GPT volume but I don't see that being an option currently.

Hi Vincent,

As you said it is a limitation of dynamic disk:

https://technet.microsoft.com/en-us/library/cc773268%28v=ws.10%29.aspx

Up to 64 TB for spanned and striped volumes. (2 TB per disk with a maximum of 32 disks per volume*.)*

As you have many disks, a workaround is to create another spanned volume instead of using a single hugh volume and keep creating virtual disks.
