Hello.
Just as a quick update.
Since I installed the HP intelligent provisioning update, there has been no issue with accessing the ReFS volume.
I have changed two jobs, one is writing backups to the RefS iSCSI target, the other one to the local ReFS SAS volume.
Reading data for the "to tape job", is no problem as well.
The last time it worked for about two weeks and not all of the jobs are writing to the ReFS volumes.
But, as I wasn't even able to rescan a repository, this is already a progress.
I will change the last two jobs on Friday, so they can create a new full backup during the weekend.
I will keep you guys updated and hope that there is a MS fix soon too.

John

Also anxiously awaiting the MS update. Just deployed two proxies with ReFS repositories and have migrated a lot of jobs.
For the moment backup speeds are screaming but they haven't built up their configured restore points yet.
When the jobs start their synthetic operations I hope not to run into any issues or have a fix from MS by then.

@j.forsynthe are you also running verifier ? Sad to say my box froze today, even with verifier on it failed to create a dump file. It was just frozen at the login screen (Press CTRL + ALT + DEL to login).

No i think this might fit:

Addressed additional issues with updated time zone information, Internet Explorer, file server and clustering, wireless networking, Map apps, mobile upgrades for IoT, display rendering, USB 2.0 safe removal, multimedia, Direct3D, Microsoft Edge, enterprise security, Windows Server Update Services, storage networking, Remote Desktop, clustering, Windows Hyper-V, and Credential Guard.

As i said above there is a much newer refs.sys in there

Gotta love how Microsoft has offered less and less information about changes they make over the years. 10 years from now their KBs will just contain $null

Presumably, it fixes one issue around ReFS, but not "our" issue. I am planning to ping ReFS team this week unless they post the blog they were going to soon.

But it does fixes an issue around ReFS that could lead to corrupted metadata so I would say a rather important update, even if it doesn't fix our issue.

I haven't read the whole 6 pages but from the sounds of it I should stick with my current Server 2012 R2 NTFS until these issues are resolved or is Server 2016 ReFS 64K the way to go?

David,

The potential of having issues with 64K are much lower then with 4K. But we have already a report here that it can happen with a very large 64K ReFS volume also. On the other hand, there are many that have 64K volumes with no issues. If you have the possibility to wait until MSFT has solved it. Why not, but it would be a shame if that would put your ReFS 2016 plans on hold for a long time since the benefits of block-cloning API are really cool.

My 2 cents
