I've just loaded NFS on our 90x running 4.0, and I have this problem:
1) I mount the pyramid's /u1 filesystem on my sun:
# /etc/mount andromeda:/u1 /mnt
#
2) I cd into the mounted filesystem:
# cd /mnt
#
3) I check to see if everything's there:
# ls -l
total 0
#
This can't be! My whole filesystem including /u1/dave should be there!
4) Just to be kinky, I see if my directory is indeed inaccessable:
# cd dave
#
5) Is anything there?
# ls -l
total 0
#
6) Let's try catting a file:
# cat mbox
------- mbox type stuff appears ---
#
It's as though every directory on the pyramid has read permissions turned
off. I checked the mount point on the sun, and it DOES have read and ex-
ecute permissions. The filesystems are all properly exported.
The RTOC seems to think the problem is on the sun for no particular reason.
I explained to him that I've been mounting file systems between suns for
months without problems... he says he'll get back to me.
Have any of you folks had this problem? Romain... are you out there?

You're taking into account the uid 0 -> uid -2 mapping here, right? It seems that you're running as root on the Pyramid. What do the permissions and the ownerships look like on the directories you're poking. It does seem strange that you're seeing the symptoms you're seeing, but I haven't sat down and thought hard about how such things might occur, or even if they might occur. -Steve

There was a series of fixes in 4.0 PTFs to problems with directory reading between Suns (and PCs) and Pyramids. Most of these involved the Pyramid as client. The customer should move to the latest PTF if it has not already been installed. In addition, OSx 4.1 has many improvements (functional and performance) over earlier releases of NFS. sas ---- Scott Schoenthal sas@pyrps5.pyramid.com Pyramid Technology Corp.

Indeed, the problems we were having were kernel related directory reading problems which were fixed when I applied the PTF's that Scott sent me.
