NFS Mount Fails at 3rd Mount command

If I try to run the following commands on a OpenVMS System 9.2-1 running on VMware to mount some folders on another OpenVMS system via NFS. Two NFS mounts are working, the third always fails independent from the order of the commands.
The other system is an Alpha Workstation running OpenVMS V7.3-1.
Code: Select all
$ TCPIP MOUNT DNFS20: /HOST=PDS_BACKUP /PATH="/RDISK/EQUALRUN/ATO" /GROUP /WRITE /TIMEOUT=00:00:05 /UID=1 /STRUCTURE=5
$
$ TCPIP MOUNT DNFS10: /HOST=PDS_BACKUP /PATH="/RDISK/EQUALDTB/PDS_DB" /GROUP /WRITE /TIMEOUT=00:00:05 /UID=1 /STRUCTURE=5
$
$ TCPIP MOUNT DNFS11: /HOST=PDS_BACKUP /PATH="/RDISK/EQUALBAC/PDS_DB" /GROUP /WRITE /TIMEOUT=00:00:05 /UID=1 /STRUCTURE=5
Any ideas?

Please provide the full messages returned by the 3 mount commands - the two successful mounts and also the failing mount.

Hi
Thank you for your interest.
The mount commands
Code: Select all
$ TCPIP MOUNT DNFS10: /HOST=PDS_BACKUP /PATH="/RDISK/NYTCPDTB/PDS_DB" /GROUP /WRITE /TIMEOUT=00:00:05 /UID=1 /RETRIES=3 /STRUCTURE=5
$ TCPIP MOUNT DNFS11: /HOST=PDS_BACKUP /PATH="/RDISK/NYTCPBAC/PDS_DB" /GROUP /WRITE /TIMEOUT=00:00:05 /UID=1 /RETRIES=3 /STRUCTURE=5
$ TCPIP MOUNT DNFS20: /HOST=PDS_BACKUP /PATH="/RDISK/NYTCPRUN/ATO" /GROUP /WRITE /TIMEOUT=00:00:05 /UID=1 /RETRIES=3 /STRUCTURE=5
provide the following messages:
Code: Select all
%TCPIP$DNFSMOUNT-S-MOUNTED, /RDISK/NYTCPDTB/PDS_DB mounted on _DNFS10:[000000]
%TCPIP$DNFSMOUNT-S-MOUNTED, /RDISK/NYTCPBAC/PDS_DB mounted on _DNFS11:[000000]
%TCPIP$DNFSMOUNT-E-MOUNTFAIL, error mounting _DNFS20:[000000]
-SYSTEM-F-REJECT, connect to network object rejected
If I change the mount sequence, I get the same error for one of the other devices e.g. DNFS11.

Indy,
I've tested this on OpenVMS x86-64 V9.2-1 against an VSI OpenVMS Alpha V8.4-2L2 NFS server running TCPIP V5.7 - ECO 5 and I can mount 3 NFS shares without problem.
A -SYSTEM-F-REJECT, connect to network object rejected message implies, that the problem most likely is on the remote NFS server. Check OPERATOR.LOG on that NFS server or enable OPCOM messages using $ REPLY/ENABLE. Then retry the mounts and look for error messages.
Volker.

OK.
The Operator.log contains some logs.
Code: Select all

To me it lokks like the third connection is accepted, but not the mount.
I also noticed, that the gid=330 is not correct. I tried the mount command with gid=320 (how the Proxy is defined) but the log shows gid=330, which is the gid from the client user.

Indy,
please also check SYS$SYSDEVICE:[TCPIP$NFS]TCPIP$MOUNTD_RUN.LOG and/or the portmapper log file SYS$SYSDEVICE:[TCPIP$PORTM]TCPIP$PORTM_RUN.LOG
If you want to test, whether this problem is caused by the NFS server or the NFS client, you could try those 3 mount commands to your local V9.2-1 server after configuring the local NFS server accordingly.
