Thanks for responding Peter. We have autofs v4 compiled into the kernel (2.4.12), and the userspace tools are autofs-3.1.7-14 which comes with Red Hat 7.1. Actually this brings up something I hadn't considered before, do we need a specific version of the userspace tools to use autofs v4 services in the kernel? Darrel Hankerson said that he was using autofs v3 to connect to solaris 8 servers and suggested that we drop down to autofs version 3. Maybe that would help, but since autofs v4 is where the current development is I am hesitant to move away from it. From my (user) perspective, it definitely seems to be a problem with how autofs is passing arguments to the NFS client software, because I have no problem mounting things directly. The strangest part is that I can get autofs talking to Solaris NFS servers, but only if I force tcp mode. Mounting NFSv3/udp (default settings) from Solaris servers only works if I do it manually via 'mount' or /etc/fstab.
Right now we have worked around the problem by forcing autofs to use tcp mode (which lets us talk to the solaris boxen) and mounting the linux filesystems through /etc/fstab. This works but it's a hack, we would like to use autofs for everything if possible. Any help you can offer would be greatly appreciated! Thanks again, aaron p.s.
