[comp.sys.hp] NFS HP bug...

We have a very diverse NFS network of Sun, HP, DEC, and SGI computers
here and have never seen the symptoms you describe.  We have
disabled "nobody" mapping in our 300 cluster so we can do backups,
but this only allows root access.  Files created are correctly
mapped to the UID of the creating remote process.  A thought:  do
all your machines accounts share identical passwd entries, including
UID and group numbers?  You must have a unified passwd file to make
NFS work correctly.

The SGI machines are a constant NFS problem.  Disks mounted from
the HP show 0 blocks if you issue a bdf command.  File access
from the SGI to the HP is very unstable (sometines it works,
sometimes it gets a partial listing, sometines it hangs).  Best
we can see there appears to be a YP interaction on the SGIs.

Can you give us a discription of your network, what machines you have
and some details of your account structure?
