OpenVMS and Mac NFS issues
rcyoung
OpenVMS (8.2) from/to the Mac (10.6.6)? I can get the Mac volume
mounted over on OpenVMS, but any attempt to do a "dir" or "copy"
results in a timeout. Here is the terminal output
On OpenVMS, the Mac volume is mounted

When you go to the OS, you can see the disk (aka DNFS16), but no "dir"
is possible (you timeout)

File protection is generally the big problem. And not obvious how to fix
properly. Not it doesn't generate the timeout errors you see.

I can reproduce this if VMS creates more than 315 versions of temp.png
(perhaps it is a limit on number of files in a directory).
This problem surfaced with an upgrade of OS-X, it used to not be a
problem before. My VMS config has not changed.
I am not sure if you are hit with the same issue.
VAXman-
Hmm. OK. First look at the Mac.
What's in your /etc/exports?
Try just:
/Users -alldirs -network xx.yy.zz.0 -mask 255.255.255.0
Use your network in lieu of xx.yy.zz.0
Make certain nfsd is running:
% sudo nfsd status
nfsd service is enabled
nfsd is running (pid 376, 8 threads)
Make sure that the nfsd sees the /etc/exports
% sudo nfsd restart checkexports verbose
Lastly, verify your GID/UID with 'ls -ln'
On my MacBook Pro, these are 20 and 501, respectively.
On VMS:
TCPIP> SET HOST mbp /ADDRESS=xx.yy.zz.nn
TCPIP> ADD PROXY <localVMSusername> /GID=20 /HOST=mbp /UID=501
Check that you can actually see your NFS server on your Mac and that you
can get to it. You may need to access and change things in your Mac's
System Preferences->Sharing.
$ TELNET/PORT=2049 mbp
%TELNET-I-TRYING, Trying ... xx.yy.zz.nn
%TELNET-I-SESSION, Session 01, host mbp, port 2049
helpNET-I-ESCAPE, Escape character is ^]
%TELNET-S-REMCLOSED, Remote connection closed
-TELNET-I-SESSION, Session 01, host mbp, port 2049
$
Then and only then, you can use your MOUNT command

on your mac:
cat /etc/exports
And you will see the config for the "disks" you are exporting.
rcyoung
should have reread the posting to see he was talking about the
"contents" of the /etc/export file. Just want to be sure I "catch
myself" on that one before everyone thinks I'm a dolt.....it's been a

moving files from OpenVMS to Unix/Mac/Windows. All those "pesky"
OpenVMS file attributes that sometimes get "corrupted".
If I am storing Mac files on OpenVMS I don't see a problem.
But if I move a file from OpenVMS (save a backup saveset), and then
move it back to the same or different OpenVMS system from the Mac,
will there be any "problems" you can think of??
John E. Malmberg
I do not know how anything other than HP TCPIP does it.
Some of this is controlled by the mount options.
The VMS attributes for the file are put in a second "hidden" file with a
name that is based on the file name.
I have seen two issues with using NFS files on VMS served from Cygwin NFS.
The VMS debugger, at least the Motif version of it will hang if the
source files are on an NFS disk.
The DCL search command also hangs when searching files on the NFS disk.
The only way to clear the hang appears to be to stop the hung process.

Most reliable way I have found is to ZIP the files on VMS and unzip them
on the mac. This way text files take on native Unix attributes, at which
point VMS can access them as stream-lf files.
VAXman-
On your Mac, in your $HOME directory, issue either (examples with me logged
in as VAXman):
% pwd
/Users/VAXman
...or...
% echo $HOME
/Users/VAXman
The /Users in the /etc/export refers to the /Users directory where Max OS X
builds all user's account home directories. The manpage 'man exports' says
this:
The first field(s) of an export entry is a list of directories on a local
file system to export. At least one pathname must be to an exported
directory. Other pathnames may refer to sub-directories of the exported
directory to indicate that hosts are also allowed to explicitly mount
those sub-directories of the exported directory. (Note that the -alldirs
flag can be used to allow mounting any sub-directories of the pathnames
specified.)

Maybe I presumed you were more than a novice with nfs. Perhaps, I should
have explained that with greater detail.

As long as you're not a faineant dolt and you learn something, I wouldn't
think you a dolt.

I haven't done this with HP's IP stack, but I have done it with
Multinet.
The one issue I ran into was that Multinet was using an older NFS
protocol and the Mac wasn't failing over to it. When I forced the
Mac to use the older protocol, it ran fine.
Bob Koehler
Yes. Sadly, even Mac uses a brain-dead file system and can't
properly track file attributes. Various FTP clients and servers
have workarounds for this, but not NFS.
Richard B. Gilbert
WHAT PROBLEM ARE YOU TRYING TO SOLVE??????????????????????????????
I can't think of any "problem" but I would not want to experiment
without first making backups of all disks that I would be writing to.
If I had important stuff on disks on this system I would want to make
backups of EVERYTHING.
rcyoung
posting). They display a bit "funky" but "any port in a storm"........
Now let's time travel a bit...to OpenVMS 7.1 and UCX. I have tried
setting up the same thing on the older system, and have a glitch in
that the NFS client is not creating the mount point automatically
(screen immediately follows) . Using same settings as before (except
VMS username is different), and I am only using the VMS NFS client in

Yikes... back in those days, I used MultiNet. I'll defer to somebody
else to answer that for you.

Now another issue....NSF keeps the VMS file characteristics in
"invisible" ADF files created along with the OpenVMS files on the NSF
server...so far so good.
If one were to try a ZIP from the VMS side, of a file stored on a NSF
volume, would it "automatically" incorporate the file characteristics,
or would they be "lost" ? Remember they are kept in a separate file
under NSF, but does the OS "automatically" bring them in when the
files are "accessed" and zipped???
Don't I come up with the most "interesting" questions?????

I *think* there are settings on the VMS side on whether attributes are
saved or not. I have found NFS to be unreliable for large text files.
Here is an example:

So it appears to work
rcyoung
backup saveset on the NFS disk of various hard drives. THe 2-4Gb disks
seem to work. But the 32Gb RAID array
image backup "dies"...the backup command executes, but the saveset
file gets to around 4 Gb and then things go crazy, and in the in the
saveset file is suddenly < 2Gb in size...yet looking at the log on VMS
shows everything seemed to be fine. So the backup command "thinks" it
is ok...but something in the NFS is killing it.

Are you talking about VAX, Alpha, or Itanic? I would not be totally
surprised if a VAX couldn't do it. The Alpha and Itanic architectures
should have no problem.

Alpha----but I have seen posts going back several years where people
"alluded" to, but did not provide a lot of info, on NFS probs with
large files. Maybe this is why?

Your first post indicated VMS V8.2, this now looks as it's a much older
version. I know from experience that VMS $BACKUP had no possibility to
write tape savesets of larger than 4GB on that version. ISTR that the
error messages were the same as above. Maybe the same restriction
applies to disk save sets?

I believe that older versions of NFS support only 32 bits in the file
size. This would explain the 4 gig limit.

7.1 thru 8.2 VMS systems. Wouldn't it be nice to find (1) solution
that worked across the board? Oh well, time will tell.

This is the problem I mentiond in my other post. Above 2GB (or was
it 4GB?) the saveset contents "wrapped" to the beginning. It was easy
enough to see when I did a DUMP of the saveset.
