[ISSUE] b20251 b20257 b20262 b20270 b20282 b20287 Formatting a volume fails
YanranHao yes sure you see the the error message on diskpart (even with the latest build and other disks (SATA,NvME / vendor and MS defaut storage drivers - I want to guess it is not a driver issue at all)
OK - diskpart
OK - sel dis x
OK - clean
OK - convert gpt
OK - create part pri
NOT OK - format fs=xxx quick

- YanranHaoMar 24, 2021MicrosoftThanks for the followup. To collect time travel, first set up time travel debugging as described at Recording Time Travel Traces. Then run the below commands.
net start smphost # this is to ensure that the mispace process is up and running
$id = (Get-Process | ? { $m = $_ | Get-Process -Module -ErrorAction SilentlyContinue; $m.FileName -like "*mispace*"}).Id
start tttracer.exe "/attach $id" # note the ""
<run repro>
tttracer.exe /stop $id
The file will be dropped at .\svchost01.run. - Karl-WEMar 21, 2021MVPSure I can try this too. Yet by design create part pri will automatically select the new part and it should be active as well by default.

YanranHao I tried to repo with the latest 20317 build.
Repro steps: reset drive via Server ManagerTry format via Server manager (incl. initialize GPT)
fails at formattingThis is the output after the known error in diskpart.
Interestingly everything seems fine here.
The Server ManagerOK - initialized the drive as GPT
OK created partitions as expected
NOT OK - even created a volume but it is marked offline (corrected manually - diskpart online)NOT OK - both volumes are RAW
As suggested I marked it online. As said it is selected by defaultassign letter x
format fs=ntfs quick
Format-Volume and also Server Manager Format... works either way.
So the issue is in the commandlet "New-Volume" which is used in the Server Manager wizard to complete following tasksOK - initializing
OK - Partitioning
FAIL - formatting (volumes remain RAW and primary partition if marked offline with no mounting point or FileSystemLabelYanranHao it is clear now that the root cause is in Server Manager and the underlying PowerShell command "New-Volume" used by Server Manager
as pure formatting works with:- diskpart > format
- Server Manager aka PowerShell Format-Volume
- format.comHow should I proceed with the time travel debugging. Which process to monitor? Thanks!
- Karl-WEMar 25, 2021MVPHello it smphost or snmphost?

Hello YanranHao i have reproduced the issue with Server Manager and recorded it. I have sent you the Onedrive link in a direct message.
let me know if there is anything else I can do and if the file is helpful. Otherwise I can also try to repeat directly with PowerShell New-Volume if this record does not include enough or relevant data. - Karl-WEApr 08, 2021MVP
YanranHao I have decided to install this server from scratch. I can confirm this has fixed the issue.
It seem there was a problem with PowerShell New-Volume introed in B20251 which did not fix with upgrades to later versions.
Now I have installed b20234 from scratch the issue is completely gone.
Maybe you can find something in the logs but it seems to be a local issue that happens when upgrading from previous versions.Thanks for your time. I will retry the behaviour once after upgrading to 20239 or later to make sure it does not reappear, is this ok?
