Hi folks,
we are having issues running chkdsk on our disks. Our system looks like this:
- Windows Server 2016
- 6TB Disk (NTFS filesystem)
The disk is part of a Windows Failover Cluster and says "scan needed" within Failover Cluster Manager and when running "Get-Volume" command.
We try to run "chkdsk /scan" command, but it takes for ages.
It is running for almost a week already. It is at stage 2 at the moment, the ETA shows 100 hours to go, but this time is increasing instead of going down.
What can we do here?
Chkdsk seems not to be capable for such big disks. Is there an alternative? Or how can we speed up the process?
Thanks

Did you observe any error which leads you to run this command?
Do you have access to a Windows 10 or Windows 11 PC?

No errors so far, but Windows does not say to run a scan without reason, right?
No access to Windows 10/11 PC. What would be the purpose of that?

2023-06-07T19:07:40.6766667+00:00 Have you look into the Event Viewer or Log files?
I guess this is not supported scenario but it required testing.
I am asking you about Windows 10 or Windows 11, because you have Feedback Hub app and you may report this issue (even for Windows Server).
You may check with Microsoft Support too.

2023-06-08T10:21:53.36+00:00 Event Log doesn't say anything.
Why is it not supported? A SAN-connected disk is standard in enterprise world, and that's what Windows Server is used for, right?
MS Support simply says "Wait for it to finish...", but that's not really helping.

2023-06-08T19:24:40.3233333+00:00 I am referring to case of running Disk Check on large number of file.
I advise you to file a bug report using the Feedback Hub app.
