Cannot extend volumes on WIndows Server 2019?

Question

I have a VMware ESXi 7.0 backed Server running Server 2019. I have 5 disks on the server and need to extend 2 of them. In VMWare, I have allocated more space (4.5->5.75TB on one, 3.5->4.75TB for the other). After running "Rescan Storage" from "Server Manager -> File and Storage Services -> Volumes -> Disks" I see the correct capacity. When I click a drive, see the desired volume, and right click it to "Extend volume" I am shown a maximum size that is the same as the original volume. I have confirmed that the disks are GPT partitioned, and the unallocated space is directly after the NTFS drive.

Any advice is appreciated.

Answer 1

Hi,

Would you please show us the screenshot of the disk and volume in disk management?

Besides, please check if use the command diskpart to extend volume could work?

diskpart
list disk
select disk <>
list partition
select partition <>
list voume
select volume <>
extend
extend filesystem

Thanks for your time!
Best Regards,
Anne

It appears the CLI version works:

PS C:\Windows\system32> diskpart

Microsoft DiskPart version 10.0.17763.1554

Copyright (C) Microsoft Corporation.
On computer: *****FILE-02

DISKPART> list disk

Disk ### Status Size Free Dyn Gpt

---

Disk 0 Online 60 GB 0 B *
Disk 1 Online 4096 GB 0 B *
Disk 2 Online 2048 GB 0 B *
Disk 3 Online 5888 GB 256 GB *
Disk 4 Online 4864 GB 358 GB *

DISKPART> select disk 3

Disk 3 is now the selected disk.

DISKPART> list partition

Partition ### Type Size Offset

DISKPART> select partition 1

Partition 1 is now the selected partition.

DISKPART> list volume

Volume 5 F ShareRoot NTFS Partition 2047 GB Healthy
Volume 6 G Comms NTFS Partition 5631 GB Healthy
Volume 7 H IT NTFS Partition 4505 GB Healthy

DISKPART> select volume 6

Volume 6 is the selected volume.

DISKPART> extend

DiskPart successfully extended the volume.

DISKPART> extend filesystem

DiskPart successfully extended the file system on the volume.

DISKPART>

That will do it; maybe there's an error in the servermgmt tool in Server 2019? This is our first Server 2019 system and it works all the time in server 2016.
