Here is the scenario. I have two RHEL 6.5 Workstations. Workstation1 has a partition that needs to be mounted on Workstation2.

The following is what I did to configure Workstation1 to be able to export the /share partion.
1. I set up the /etc/export file on Workstation1 to read
/share IPWorkstation2(rw)
2. ran exportfs -ra to make the changes in th export file take place
3. Made sure that NFS Service was running and retarted the service and the machine and checked it again.
4. No entries were made to the host.allow or deny files so NFS should let Worstation2 through.
5. On Workstation2 I created the /share mount point.
6. From Workstation2 I ran mount IPWorkstation1:/share /share

NFS times out like it cannot reach Workstation1. Workstation1 can be pinged by name or IP. I can ssh into Workstation1 from Worstation2, so connectivity does not seem to be the issue.

I have looked at the file /proc/fs/nfs/exports and there is no info in that file. This may be the problem, but this file is supposed to populate automatically when I run exportfs -ra and/or a reboot happens and Linux sees a change to the /etc/exports file.

Anyway I have exhausted all Google searches and spent too much time, so reaching out for some ideas. I must be missing something very simple...

if you do exportfs -av does it say it is exporting /share ?
if you do netstat -at | grep nfs does it show nfs as listening?

Have you ever try to open the filter to * to begin with? What errors are you getting?

/share *(rw)

Open in new window

Yes - Says it is exporting IPWorkstaion2:/share
Yes - tcp 0 0 *.nfs *:* LISTEN

/share *(rw)


Are you talking about editing the /etc/exports with this?

Just for testing if you can ignore security for some time use below

#service iptables stop
#setenfore 0

Then try to mount it on another node.

Bingo!

Mounted immediately. Can you give brief description of what we just did and how to edit the IPTables to allow the mounting?

You need to add a rule to allow 2049 and 111 port connections in your firewall..

Would be nice to have an admin of this calibre to work with. I spent 13 years in Windows and was made a Linux/Unix admin out of necessity. At times just Google and EE at the helm here. Can be very overwhelming at times. Thanks SA!
