[ReFS] BSOD after installing March 2025 Cumulative Update

[Gostev]

Please be aware of the newly introduced ReFS regression that may cause your backup repositories to BSOD. We have updated (right at the top) the ReFS Known Issues, Considerations, and Limitations support KB article with the latest information we received from Microsoft. This seems to affect all supported Windows versions.

This is all we know about the issue at the moment.

Thanks

Thank you very much for this warning.
Does this also happen when ReFS filesystems are attached but there is nearly no IO to these? We just finished migrating to XFS but our old repos are still attached to our main Veeam server.

I wonder: Has something like this ever happened with XFS?

Unfortunately the above is literally all we know about the issue at the moment, no further details have been provided by Microsoft.

Wanted to comment on this as from my time in Support, I can only recall 2 times when XFS was a factor in significant issues in the Veeam infrastructure; one time ended up being an issue in the distribution (Ubuntu, EDIT: issue was identified as this, already patched in Ubuntu) and the other ended up being an /etc/fstab misconfiguration unrelated to XFS that was hard to spot (Veeam logging helped catch it though)

XFS has proven to be exceptionally reliable and resilient, so while I wouldn't say XFS is immune to such issues, it seems quite battle-tested.

Really impressive.
This all shows that Veeam has really put its bets on the right horse. The posibility of using LVM alone has made our live so much better.

Thank you!!!

Does anyone know if this was actually resolved in one of the subsequent CUs?

Want to Bump this. Has this been resolved with Windows newer cumulative updates?

While we wait for a patch or more information from Microsoft, does your team recommend any interim solutions to mitigate the risk of BSOD when using ReFS?

According to the KB article linked in the first post, this issue was supposedly resolved with April Windows updates.
