Hi!
I have a 2-node Windows Server 2016 failover cluster set up as a file server.
Disks are SAN LUNS mapped as raw devices to the vmware virtual machine.
We have configured data deduplication on the volumes and it seems to work since we have gotten more free capacity on the volumes.
However, when looking in the server manager GUI it most of the time shows no deduplication status at all, and when clicking configure data deduplication the setting is shown as disabled. (The dedup information is visible there occasionaly, but it seems completely random if it shows it at all).
But when running the powershell command Get-DedupVolume it correctly displays the status and dedup beeing enabled.
(I was hoping to be able to post screenshots of server manager but for some reason I get the message that my account is not verified and no information on how to verify it). But I can at least post the output of the PS command.
PS C:\Windows\system32> Get-DedupVolume
------- --------- ---------- ----------- ----
True Default 1.36 TB 47 % G:
True Default 3.47 TB 28 % E:
True Default 1.52 TB 38 % F:
Anyone else got this problem with server manager? Is there a workaround?
Kind of annoying not to be able to trust the information shown. (I assume that PS is correct in this case).
BR
