Failure to mount disk on NFS client

Rajeev Hejib — Tue, 24 May 2005 06:27:25 GMT

I get following error:

SMIV14 » tcpip mount dnfs201: /host=smiv96/path="/nfsdsa201"
%TCPIP$DNFSMOUNT-E-MOUNTFAIL, error mounting _DNFS201:[000000]
-SYSTEM-F-INVLOGIN, login information invalid at remote node

Same works on other node

SMIV15 » tcpip mount dnfs201: /host=smiv96/path="/nfsdsa201"
%TCPIP$DNFSMOUNT-S-MOUNTED, /nfsdsa201 mounted on _DNFS201:[000000]

NFS Server is on Alpha 4100 with
OpenVms 7.3-1
TCP/IP V5.3 - ECO 2

NFS Client with problem is on MicroVAX 3100-95 with
OpenVms 7.1
TCP/IP V5.0

NFS Client where it works is on MicroVAX 3100-95 with
OpenVms 7.1
TCP/IP V5.0A

Only difference I see is with TCP/IP version. I am mounting the disk as user - system

Proxies on NFS server
VMS User_name Type User_ID Group_ID Host_name
DECEDI OND 1 1100 SMIV15, smiv15, SMIV14,smiv14
EDI_GATEWAY OND 0 1100 SMIV15, smiv15, SMIV14,smiv14
EDI_WATCHDOG OND 2 1100 SMIV15
SYSTEM OND 4 1 smiv15, SMIV15, smiv14,SMIV14
TCPIP$NOBODY OND -2 -2 smiv96, SMIV15, smiv15

Can someone please help? Than

Did you restart the NFS server ? In pre-5 this was often needed because the server cached certain info.
Did you check for intrusions ?

Error indicates that login to mount isn't valid in remote node. Are you check permission of mount for SIMV96 node from SIMV14?

Sorry.
Check export of /nfsdsa201 on NFS server.
Is activated to SIMV14 node?.

Saludos.

Thanks guys for your help. I have tried it and it still fails.

I have stopped and restarted NFS server on SMIV96. There are no intrusions.
export on SMIV96 is
SMIV96:MGR> ucx show export

File System Host name

/nfsdsa200 *
/nfsdsa201 *

and
SMIV96:MGR> ucx show map
Dynamic Filesystem Map
Pathname Logical File System

/nfsdsa200 DSA200:
/nfsdsa201 DSA201:
SMIV96:MGR>

When I did reply/enable on SMIV96 and mounted the disk on SMIV14 I get following on SMIV96

SMIV96:MGR>
%%%%%%%%%%% OPCOM 24-MAY-2005 15:09:48.93 %%%%%%%%%%%
Message from user TCPIP$NFS on SMIV96
%TCPIP-S-NFS_MNTSUC, mounted file system /nfsdsa201
-TCPIP-S-NFS_CLIENT, uid=-2 gid=-2 host_name = SMIV14

SMIV96:MGR>
%%%%%%%%%%% OPCOM 24-MAY-2005 15:09:48.95 %%%%%%%%%%%

%TCPIP-S-NFS_UMNSUC, file system /nfsdsa201 is unmounted
-TCPIP-S-NFS_CLIENT, uid=-2 gid=-2 host_name = SMIV14

SMIV96:MGR>

IT DOES mount the disk but dismounts immediately and gives following error on client (SMIV14)

and on SMIV14 following
MIV14 Â» ucx mount dnfs201:/host=smiv96/path="/nfsdsa201"
TCPIP$DNFSMOUNT-E-MOUNTFAIL, error mounting _DNFS201:[000000]

Note the -2 in the opcom messages. Indicates "tcpip$nobody" according to your proxy setup. I think you need to define an O(outgoing) proxy on the client side. Compare with the working system. It should map the SYSTEM account.

Note that smiv96 (in lowercase) is not present in the not working part of SYSTEM.

Creating ON nfs proxy on client for the server user system made it work.
