Windows server 2016 stand desktop experience cannot use disk management to continue to use the extended volume function to expand partitions at 15T.

Question

    The Windows server 2016 stand desktop experience version uses disk management. When the disk partition is larger than 15T, the extended volume function cannot be used to continue to expand the partition. It can be completed by directly allocating a partition larger than 15T. This problem occurs in both basic and dynamic partitions.

Hello there,

To a server, it is very common to use 2TB to 4TB single disk or over 10TB RAID array. If you initialized a disk as MBR, only 2TB disk space can be used. The remaining space is shown as Unallocated, it can't be used to create new volume or extend other partition.

When you cannot extend partition past 15TB in Windows Server 2016: convert disk from MBR to GPT in advance, then you can extend partition with Unallocated space easily.
