NFS LINUX/VMS

Nobody's Hero — Tue, 17 Aug 2004 09:25:44 GMT

I have a redhat 9 system. I also have an older VMS box running NFS version 2. I want the VMS box to be the NFS server and I am having trouble mounting the Linux box to it. Do I have to do something to handle the mismatch NFS versions between the two systems? One is NFS 3 and one is NFS 2.

What error do you get?
can you see the share with
showmount -e x.x.x.x

from the client where x.x.x.x is the IP address of the NFS server?

if from rh9 you do this command
rpcinfo -p x.x.x.x
where x.x.x.x is the IP of nfs server what do get ? You should see the protocol and the version that nfs uses

by default the client tries to mount with nfs version 2.
Otherwise you can specify other version in mount option:
nfsvers=3 (for instance)

And for the bove suggestion use:
rpcinfo -p x.x.x.x |grep nfs

to narrow the output to relevant rows...

IHS005 is the nfs server
techweb3 is the RH9 system that I am trying to mount.

How do you try to mount it on the linux and what is the error returned if any ?

Do you see error on the vms side
does a
$reply/enable=all
on the vms side

then try the mount (from linux) again and see if you get meaningfull message in the vms session ?

Maybe this will give more info on what this problem is ... if all fail's perhaps you could enable this in the audit trail on the vms side and see what this reveals.... in fact maybe you should post this also in the Openvms forum ... I have done year's of vms system management but this is also some years back and surely the vms forum will carry lots and lots more knowledge then your poor servant.

in any case keep us informed .

the output show that the NFS server uses version 2 (like you said) , and UDP proto.
By default the client tries to connect with UDP and version 2.So technically you shouldn't have problems...What error message do you get if any and what is the command that you use to mount that directory....
