of NFS offered, however this might not be the cause of your problems. So, could you login as root to the RHEL3 boxes http://serverfault.com/questions/182851/getting-input-output-error-from-nfs-client-on-rhel5 and do an: rpcinfo -p server (server=resolvable name of your RHEL5). and provide the output? Also, what are the mount options you use on the /etc/fstab file (or automount config) on the RHEL3 side to mount the home dirs from RHEL5? Do the NFS imported https://www.redhat.com/archives/redhat-list/2008-February/msg00129.html partitions show up in df, does it hang, display the partitions as mounted but with no util info?...

I can ssh into the workstations but creating files gives the same Input/Output error. The server hard drives are fine BUT I do see this in /var/log/messages on every occurrence on the clients: kernel: svc: unknown version (3) I'm not able to log into the clients from the GUI so something serious is going on.

trying to mount a NFS shared folder on CentOS 6.4 from CentOS 5.9 and found a really tricky problem. I've added the /etc/fstab entry, but once I ran https://gerrydevstory.com/2013/11/12/mount-nfs-inputoutput-error-when-mounting-from-centos-5-9-to-6-4/ mount /my/folder it stuck for 2-3 minutes and came back saying mount.nfs: Input/output error Things I've Tried This is all the things I've tried with no success: Ensured network connection was ok. I checked the firewall / iptables and made sure the client machine can connect to NFS server Checked my /etc/hosts file, ensured no dodgy entries Double checked /etc/exports and ran exportfs output error -r on the NFS server Ran showmount -e [host_ip] to check the NFS server really does advertise the shared folders Ran rpcinfo -p [host_ip] to check the version and supporting services are available Rebooting the server many times Solution Thanks to this post from linuxquestion.org forum, the solution was to add nolock option to the /etc/fstab file. 10.0.10.10:/my/folder /mnt/nfs/my/folder nfs nolock 0 0 CentOS input output error manual is pretty vague as well on what this option really does, but oh well it seems to do the job for time being nolock — Disables file locking. This setting is occasionally required when connecting to older NFS servers. centosnfs Post navigation Previous PostCentOS / RHEL NFS Share Network Folder MountingNext PostBinding a List Request Parameter on Spring MVC Leave a Reply Cancel reply Gerry's software development journey of trial, errors and re-trials Sponsored Content Recent Posts Google Chrome Taking 16GB of my Macbook Air Managing Spring Security User Session Why You Should Use Java 8: NullPointerException Free Object Access Using Optional Using ZeroMQ Java Binding ZeroMQ Windows Java Binding: Building libzmq.dll, jzmq.dll and zmq.jar Using Visual Studio 2012 Archives Archives Select Month November 2015 August 2015 July 2015 April 2015 March 2015 February 2015 January 2015 December 2014 November 2014 October 2014 August 2014 June 2014 May 2014 April 2014 March 2014 February 2014 January 2014 December 2013 November 2013 September 2013 August 2013 July 2013 June 2013 May 2013 March 2013 September 2012 August 2012 July 2012 June 2012 May 2012 Sponsored Content Proudly powered by WordPress
