Well, I'm not sure what the issue or fix was, but this issue can be closed.
I posted the bug to the GVFS list and, amongst other suggestions, one of the maintainers noticed an error in the GVFS debug log of 2 malformed parameters in smb.conf min client protocol and max client protocol (vs the correct client min protocol and client max protocol). These nonsense parameters were also both set to SMB3 so the first thing I did was remove them from smb.conf before doing the other tests recommended. However, now my repeatable "issue" scenario writes the files properly (and the traces show a perfectly good response to the file info request that repeatedly returned access denied errors before, BUT the file creation parameter values are now different for no reason I can figure out). I tried adding the parameter lines back, as they were before, but I still can't recreate the issue. I also tried "fixing" those bad parameter lines and it prevented me from connecting to my SMB2 share at all, which I would expect when the client side is locked to SMB3. So after I pulled the lines again to let the client side negotiate naturally, I can't get the issue to happen again after repeated tests with different programs, some of which had consistent write problems and some of which had intermittent write problems. I didn't do any updates to the system in between when I posted this and when I "fixed" it and the one change I DID make I reversed, but it didn't cause the problem to recur. I suppose this is why I wanted to see if anyone could replicate this. I would bet now that they couldn't but I doubt I'll ever know what the actual issue was, now. Anyway, I'm closing this bug. Sorry for the false alarm. :) Thanks, Scott -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1815395 Title: GVFS-SMB write problems to SMB2 shares To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1815395/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
