/data/LCTEST/TMP -rw=Ita1
/data/LCTEST/TMP -rw=Ita2
/data/LCTEST/TMP -rw=Ita3
-
And ejecuted the "exportfs -a".
-
/etc/hosts are alseo set to resolve Ita1, Ita2, Ita3 to the correct IPs.
-
I have mounted this filesystem from a Red Hat Enterprise Linux 3 Server, and I can read but no write from the Linux server.
-
Any idea about the problem?
Solved! Go to Solution.

SolutionCheck the following:
/etc/exports settings on Linux. They can be quire restrictive by default.
tail -f /var/log/messages
on linux
try and nfs mount. Act on or post the errors or messages you see.
I've done what you wish to do, it should be no problem.

Re: NFS from HP-UX to Linux
My /etc/exports in linux is a blank file.
the /var/log/messages in linux does not report anything when I try to write on the NFS.
This is the error that linux reports me:
[oracle@ita1 pruebas]$ touch uvr
touch: creating `uvr': Permission denied

Re: NFS from HP-UX to Linux
Have you checked the directory permissions to see if they are what's stopping the writes from succeeding? Can you try (just as a test) opening up the directory permissions to something like "777" and see if the clients are then able to create files in the directory?
If that works, you should then decide what the proper directory permissions are for your environment/applications.
Let me know if opening up the directory permissions allowed writes/creates to succeed. If it doesn't the next step would be to collect a network trace of the failing write/create attempt (with a tool like ethereal) and posting the trace here for me to evaluate.
Regards,
Dave

Re: NFS from HP-UX to Linux
Well if you are trying to mount an NFS share on a Linux NFS server, you are going to need some content as in ex exports in the Linux.
But re-reading your post, I've done it the way you have written this post. Your title was misleading. NFS from HP-UX to Linux. In that case, /etc/exports on Linux can not be blank.
Here are the new diagnostics.
tail -f /var/adm/syslog/syslog.log
Attempt your mount from Linux to HP-UX.
Report the errors. Read the /etc/exports file on HP-UX and make sure its not restricting permissions to certain hosts or ip addresses.
Better yet post your /etc/exports file from HP-UX here.

Re: NFS from HP-UX to Linux
I had this problem when I tried to do a RHEL3 to RHEL3 nfs mounting.
then I added the no_root_squash options to /etc/exports file, it works fine now. But looks like this option is not available on HPUX, have you tried to give root access to those 3 servers ?

Re: NFS from HP-UX to Linux
Try
/data/LCTEST/TMP -root=lta1
/data/LCTEST/TMP -root=lta2
/data/LCTEST/TMP -root=lta3
It will surely work.
HTH,
Devender

Re: NFS from HP-UX to Linux
Thats the file which tells what to mount and where and with which options.
It may help to use your Linux gui to help mount the nfs filesystem.
See which options it puts into your fstab.
Reading Dave Olker's NFS tuning guide may help you. He does mention something about a -C option in rpc.lockd on the server side, when going from HP-UX to Linux. Whether you need that depends on your NFS version and patch level.

Re: NFS from HP-UX to Linux
THe permision for that directory is now to 777 and the problem is still there.
Owner of source directory and owner of mounted remote host are same owner (oracle user).
