I am having a problem mounting an NFS v4 share on a RHEL6 system, when attempting to mount the file system with the command "mount -t nfs4 nfsserver:/home /media/home" I receive the following error message
mount.nfs: mount system call failed
I have other RHEL6 and Ubuntu systems that can mount this file system with no issue (same command). The strange part is that I can mount the file system from that server by forcing it to use NFS v3. I have checked the exportfs file, DNS, restarted the various NFS services with no change, SELinux and iptables have also been disabled while testing. The remote NFS server is also running RHEL6. I'm probably missing something obvious but not sure what to look for next, any ideas would be great, thanks!
