nfs problems

Heiner E. Lennackers — Mon, 08 Jul 2002 12:19:17 GMT

Please help.

If i mount a directory from my nfs server (HP-UX 10.20) i cannot access any directory which access is handled by a secondary group entry and the sgid bit.
This does not happen on a nfs server running HP-UX 11.00.
What can i do to make it going? Are the any options, kernel parameters or other things i can check to solve it?

Hello,

Are you trying this as root? How many groups does root belong to?

Can you post your exports file?

Hi!

No, i use the user account who has to use it for testing. And this is currently the only secondary group the user has. So it is not a root-squash or the to 32 limited count of secondary groups a user has problem.
I have tested it on other machines with hp-ux 11.00 or solaris 8. It seems to be a hp-ux 10.20 related problem.

Is your 10.20 machine up to date in patches?

Hello, again

I think that Harry has a good point with the patches. I would also make sure that you retrace your steps in that you have your link /etc/logingroup pointing to /etc/group and it has the appropriate permissions. That you have the sgid bit set on the directory, mounted and unmounted.

I apologize in advance if I am stating the obvious and you already have these checked

which nfs version are you running, version 2 or 3 , that could make quite a difference and 10.x standard useses version 2 and 11.x uses 3

patching is also my advise , nfs=patching , however you look at it

I had the Jun-01 patches installed, so i upgraded the machine to the latest (dec-01) general patch bundle with no effect, but after frocing the mountd to accept nfs3 calles (10.20 defaults unfortunatly to nfs2) it was working, now the clients just step down from nfs3/tcp to nfs3/upd and not down to nfs2/udp.
There seem to be some incompatibilities between nfs2 and nfs3 in handling group ids.
