I have recently updated my production storage to 25.10.
I have noticed couple of times that while trying to access my SMB share Truenas will report empty drive, when I refresh couple of times my content will show up correctly.
It also happens in opposite direction too - at one point, I tried to open PDF file which was clearly there and my windows client reported that the file I am looking for is no longer there (it opened correctly few seconds later). I have done all “have you tried turning it off and on again”, but the issue repeated itself. No errors are recorded.
My setup includes multichanell SMB and it is also true that my windows machine recently updated to 25H2 so there are many “moving parts” which makes it hard to pinpoint where exactly issue happens.
So this is just a record that something is happening (data is/appears safe), so if anyone has a clue or idea where to look for issues, or you notice something similar, please let me know.
I can confirm I have the same issue on multiple machines with Windows 11/10. Was really stressed about it for the first couple of times, thinking everything was gone.
I’m not seeing this in my lab with default settings for 25.10.0. I’ll need explanation of minimal test case for this, or someone to PM me for a teamviewer session some time next week (I’ll probably have to install development tools and debug symbols so that I can gdb attach to the SMB session).
Examples of relevant information:
share configuration midclt call sharing.smb.query | jq and select out relevant share config
ACL configuration getfacl <path> or nfs4xdr_getfacl <path> depending on underlying ACL type.
whether share path is being accessed by apps / containers / NFS server as well as the SMB server.
Reposting here, you can send message directly to me.
