Hello all, Recently, my lazy ass went from 4.6-current snap to the most recent 4.8-current snap (#647: Fri Nov 26, amd64). Machine in question is mostly a local file server, NFS to a few Macs. I say mostly, 'cause it does some other stuff, and sits in a DMZ.
Since the upgrade to 4.8, I'm unable to read /some/ files from the nfs server to the macs. I say some, because in testing I've been able to ascertain the following: 1. I can write any size file from the mac to the nfs server. No issue. 2. I can write a small file (like 5 KiB), and read it back to the Mac. 3. I can write a large file (like 700 MiB), and cannot read it back to the Mac. 4. I am unable to read any previously existing files on the NFS share to the Mac, whether they be large, or small. Because the machine is in a DMZ, I made sure to disable the DMZ->Internal filtering rules and stuff to rule out any stupidity. Traffic dumps show no blocked packets. While grasping at straws, I set vfs.nfs.iothreads=4. The Mac is mounting the share as -o resvport,hard,intr,nolock. The troubleshooting results thus far are just erratic enough to have me believe it's nothing I've done; nothing is making sense. I'm basically looking for corroboration here. Can anyone else replicate this? -- Jason
