Just reply to the gnats entry, and I'll follow it via the web interface.] Machine A is serving via NFS. When unmounting (probably also mounting) an unrelated file system on A, B will get a EPERM error if it is simultaneously accessing files on A via NFS. I have seen this behavior at least since 5.x, probably before. >How-To-Repeat: Do heavy NFS i/o from machine B to machine A, then unmount (mount) a file system on A. B will get an error. >Fix: Unknown. >Release-Note: >Audit-Trail: >Unformatted:
