https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D208071 Bug ID: 208071 Summary: AutoFS seems to disturb NFS server Product: Base System Version: 10.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: dlt_cjo@yahoo.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org I'm currently working to move my organization from am-utils to autofs and h= ave run into a snag. I've got three non-prod FreeBSD 10.2-RELEASE-p13 (as repo= rted by freebsd-version) machines that export NFS. If I'm transferring data fro= m a client and attempt an autofs mount elsewhere on the server, the mount betwe= en the client and server seems to be disturbed in a way that I haven't been ab= le to define, as there's no in-your-face error. To recreate: * Export a file system on the NFS server(nfs3). * NFS mount the server from a client(nfs3). * Run an automatic iozone benchmark from the client on the NFS mount. (iozo= ne -a) * ssh into the server, change directory into an autofs namespace, then do a directory listing to cajole it into mounting a file system on yet another N= FS machine(nfs3). * The NFS client running the iozone should now error out with a "Can not op= en temporary file iozone.tmp for read, open: Permission denied" or "fsync: Input/output error" I can't quite place my finger on it. It seems as if the act of mounting another filesystem with AutoFS is disturbing the NFS server in some way.=20= =20 This doesn't happen when using a similarly configured am-utils as the automounter & I'm able to duplicate on all three FreeBSD machines. Running automountd in debug mode doesn't seem to report any errors that would lead = me to believe it's a configuration issue. (Though I'm certainly open to that b= eing a problem!) --=20 You are receiving this mail because: You are the assignee for the bug.=
