I am having terrible trouble with NFS between a PI and several other machines. The PI hangs (completely dead) randomly when transferring large files via NFS. The problem almost always occurs when I am reading and writing large files on NFS-mounted disks. This happens every few days when the input and output files are on the same (remote) machine, and every few hours when the input and output files are on different machines. The worst problems are with the NeXT machine (O/S 0.9), but I also get failures with SGI 3000's (O/S 3.6). The PI is running a recent version of the O/S also, 3.14711181642.... Changing things like hard vs soft mount does not help.... Is this just another SGI trick to get us to buy more disk drives for the PI? -- John D.

The 3.147... version is the original OS release for the PI, and is quite out of date by now.

The first PI release had bugs not only to do with Ethernet (which showed up best under NFS stress), but also with interrupted level management (for kernel heads, spl was busted).

Since the 3.2 Release of IRIX is around the corner, you may want to wait until then. If not, feel free to call the Hotline and ask for a maintenence tape to bring you up above Rev C (3.147XXX). The bug was fixed in Rev D, but a Rev G is also available that has the NFS patch and other patches as well. If this is your only problem, I'd stick with Rev D. Let us know if we can assist.

I am happy to report that SGI has fixed the problems I reported earlier with NFS crashing my PI. The second or third call to the hotline found someone who knew about a bug in the 3.1D revision relating to ethernet stuff. They shipped us a 3.1G tape and I have been unable to crash the system since :-). Apparently the releases between 3.1D and 3.1G were distributed only to sites which reported problems. This is a nice policy to relieve the user of the burden of upgrading all the time, but I would have liked to have heard about the existence of the upgrades and the bugs they fixed.... -- John D.

What would be nice is if they sent you a short note when ever there was a new release and what that release fixes. Then you could send them a card back if you wanted the newest release. -- Brent L.
