Robocopy error 5, 13U5

[jenksdrummer]

Upgraded 13U5 from 13U4 last night, started copying over files to a fresh pool/dataset/etc. I get to my steam library folder and it seems no matter what I do, it stalls out on certain folders with an error 5 'access is denied' error, when accessing a destination directory. I am using robocopy \\source \\destination /copy:dat /mir /r:1 /w:9999

Source system is WS2019. Copied files locally without issue. I've also manually created the directory on the destination / truenas box, only to have the directory get deleted when robocopy hits it.

Not sure what's going on here. Is there a debug log I can look at?

Work-around found, on the share, changed from "Default Share Present" to "No Preset" and unchecked box next to "Enable Alternate Data Streams", restarted SMB service. Disconnected mappings/sessions and reconnected and re-ran robocopy command and it's working now.

Now to go research as to what/why this is enabled and seems to work most of the time while enabled?

Found that the directories in question all had an Alternate Data Stream that was a 0 byte file; all Win32App_1

There was zero-length ADS on source directories? What is output of Get-Item <filename> -stream * on source Windows box?

On any of the directories that would fail to copy.

If I created a matching directory on the truenas box, then ran robocopy again, it would delete that directory as well.

I found them doing a dir /r, let me get that info and post it; have to boot the server again.

get-item 'BioShock 2 Remastered' -Stream * does not produce a result. get-item 'BioShock 2 Remastered' does return a result so that selection is viable.

Where is source and where is destination? What is output of testparm -s on TrueNAS?

get-item * -stre

Source is WS2019 and ReFS
Destination is TN 13U5

Keep in mind, I disabled Alternate Streams so I could copy off my data so that's probably what that last line is stating.
I had also set "server min protocol = SMB3" uncertain if that could be of any relevance (it wasn't)

Thanks for posting this. These steps fixed the same issue I was having.

Seems this might be fixed given the release notes of 13U5.2
