5193.0. "nfs client hangs" by UTRTSC::KNOPPERS (Oswald Knoppers) Tue Feb 04 1997 09:06
Hi,
One of my customer experiences intermittend nfs client problems. He uses an
Alpha running VMS V6.1 and UCX V4.0 w/o eco's. The remote system is a sun.
Somewere using this dnfs disk the disk becomes unuseable. It is not known
what triggers this. Trying to dismount the device gives the following:
%UCX$DNFSDISMOUNT-E-DISMOUNTFAIL, error dismounting _$1$DNFS1:
-RMS-E-DNF, directory not found
-SYSTEM-F-TIMEOUT, device timeout
I have made a UDP trace and see only empty IP packets coming back from the
sun. Can anyone tell me what could be wrong?
BTW I was able to dismount the device using the command:
UCX> dismount dnfs1:/all
Thanks,
Oswald

| Can anyone comment?
I am really puzzled by the fact that UCX sends it's UDP packets to port
32856. Shouldn't that be port 2049?
Thanks,
Oswald

| The reply packets are not even UDP. They are ICMP. I consulted MyTH
about them, and he does not understand why TCPIPTRACE does not dump
them. Presumably, they are either invalid or they are some unusual
type that TCPIPTRACE does not understand. It might be interesting to
have a look with a line monitor. If you do this, you are welcome to
post the results.
The client behavior is as expected when getting no answer from the
server.

No, 2049 is normal for the NFS port, but these are MOUNT calls, not NFS
calls. Even so, port 32856 is pretty odd for a MOUNT port also. Maybe
you should get the TCPIPTRACE going early enough to catch the client's
GETPORT call to the server's portmapper to see if it is returning the
correct port for MOUNT.

Well, I did a 'tcpiptrace/protocol=udp'. This probably explains the missing
data. I'll try to get more.
Thanks,

| 5193.4 | is this following a server host reboot? | LASSIE::CORENZWIT | stuck in postcrypt queue | Tue Feb 18 1997 16:08 | 8 |
| It has just come to my attention that the UCX client does not requery
the portmapper for the MOUNT port if it has mounted from the same host
previously. If the server host reboots, MOUNT may be using a different
port number.
This is IPMT case CFS.48976.
