Re: Problem NFS mounting Centos 7 file systems from vxWorks 5.5

[Andrew Johnson <anj@aps.anl.gov>]

Calling all RTEMS developers (Till, Eric, Michael, Heinz): Given the
statement below from Red Hat, are there any plans in the works to
support NFSv3 or later on RTEMS, or some other modern network filesystem
protocol?

The RTEMS NFSv2 client does talk to our RHEL-7.3 server with the
configuration change I posted for Mark, but the VxWorks 5.4.2 NFS client
broke somewhere between the RHEL-7.2 and 7.3 servers. VxWorks 5.5 has an
NFSv3 client (which is buggy, make sure you get all the available
patches) that works OK against a RHEL-7.3 server.

The APS now only has *2* production IOCs left running on EPICS 3.13.10,
having upgraded the others to Base-3.14.12 and VxWorks 5.5 or 6.9. This
solved the NFSv2 issue for VxWorks, but our RTEMS-4.9.2 and 4.10.2
systems are still stuck with NFSv2...
