In any case, as soon as I JLT> am able to mess with that server, I'll know more. Rebooting the server did not make any difference, and now more users are seeing the problem. At this point I'm in a state where NFS simply isn't reliable at all, and I'm not sure what to do. If Centos 8 were out, I'd work on moving to that just so that the server was a little more modern. (Currently the server is Centos 7.) I guess I could try using Fedora, or installing one of the upstream kernels, just in case this has to do with some interaction between the client and the old RHEL7 kernel. I do have a packet capture of a directory listing that fails with EIO, but I'm not sure if it's safe to simply post it, and I'm not sure what tshark options would be useful in decoding it. I do know that I can rsync one of the problematic directories to a different server (running the same kernel) and it doesn't have the same problem. What I'll try next is rsyncing to a different filesystem on the same server, but again I'll have to wait until people log off to do proper testing. - J<
