Configuring ReFS volumes in Exchange Server 2016

Share this:

How to configure ReFS volumes to be used by Exchange Server 2016 Mailbox Databases. Introduced in Exchange Server 2016, we should use ReFS volumes for Exchange Databases, index and log files. 


After adding a new disk on the server, we can open Disk Manager and the following pop-up will be displayed, we can initialize the disk like we have been doing for many years on Windows Server.


We can use the Disk Management tool to format the volume as ReFS without any issues, however we need to disable the integrity feature and that requires PowerShell.  The first cmdlet will list the existent volumes, and from that we will get the Number of the desired volume and create a partition and format it using ReFS, as follows.


Get-Disk X | New-Partition –UseMaximumSize | Format-Volume –FileSystem ReFS –SetIntegrityStreams $False


The final step is to assign a mount point or volume to the new volume that has been just created, as follows.


Using the steps above we can create ReFS volumes to support Exchange Server 2016 workloads.
