I've got an 11.2 system acting as my media server. I'm successfully exporti= ng the directory which contains the media files via NFS, so that they're accessible on my workstation, which is running Windows 10 Pro. I ca= n read the files fine from the Windows machine using the built-in Microsoft NFS client, and I can create directories, new files, and so forth= from the Windows machine in the share. The issue is that I can't copy any files greater than or equal to 1M from t= he Windows system to the NFS share. I confirmed this by using dd to create a file which is 1023k, which I was able to copy, and one which is= 1024k, which I was not. I get the same behavior whether I try to drag-and-drop into the NFS share, copy-and-paste, or using "copy" in the Wi= ndows Command Prompt. The error that Windows immediately gives me is "Error 0x8007045D: The request could not be performed because of an I/O dev= ice error." (And again, I *don't* get this error if the file is under 1M.) I've done some web searches, and there's a fair amount of that particular e= rror code--but nothing that I saw seemed directly relevant (mostly about timeouts...but I'm getting the error immediately). Maybe I'm= just bad at Google. My /etc/exports is unexceptional, literally just the line: /usr/local/plexdata -mapall=3Dplex Unfortunately, I don't have another system to hand to test mounting the sha= re. So at this point, I'm not sure where to poke. Is this something I can address from the FreeBSD side? A limitation of the Windows NFS client?= Some unfortunate combination of them? If anybody can point me in the right direction, I'd be appreciative.
