    Karl-WE two issues:

     

    1. Why did 3.10 refs refuse to mount the volume?

    There should be events in system event logs, and refs operational logs indicating the reason.

    2. Why didn't refsutil salvage work?

    Current inbox salvage is not yet compatible with 3.10 refs. We are working on it. If you are willing to test a private refsutil, please let us know.

    @RajDS_FS, are you able to provide me with a private refsutil as well? For some reason my REFS drive just turned RAW, and it is on v3.10. I need to try to recover my files. Do we have an ETA on when the updated REFSutil that works on v3.10 gets released?

    Hi RajDas_FS ,

     

    While I'm not suffering from the same problem indicated in this thread, I'm trying to use the dedup functionality and it's failing. I'm willing to test a private version of refsuti if there's still one available.

     

    I understand and accept that it could cause all my data to disappear etc.

     

    Regards,

    Matthew

    Hi,

    I now have this issue after installing the latest updates on a production copy of Windows 11, I'd be willing to try the private refsutil as I've lost my live copies and my backups.
    TIA

    Hi RajDas_FS as I have moved on, I cannot check anymore but what differed from one of the two ReFS 3.10 Volumes affected that the one that got in RAW state after IPU had a the second volume as mounting point.

     

    Such as 

     

    D:\Hyper-V 1(native volume 1)

    D:\Hyper-V 2(mounting point volume 2 on volume 1.

     

    I understand it's an uncommon scenario but it made it easier for Management purposes, and shouldn't cause a problem. Not saying it was the cause but that could be explaining this rare state. 

     

    As for ReFS salvage as I don't have the RAW volume anymore, being interested into it, is rather of theoretical nature at the moment. Good to know, though, this is a known limitation at the moment.
