We have an NFS server, running Redhat Linux 6.1. We have upgraded a number of workstations to RedHat Linux 6.2. The NFS mounted filesystems mount inconsistently between versions. The RedHat 6.2 workstations receive a 'permission denied' error when trying to mount the nfs filesystems. This did not happen with 6.1 workstations. The current workaround is to 'exportfs <workstation>:/<dir>' on the server, every time a 'permission denied' error is found. After doing so, the workstation is able to mount the filesystem. However, the workstation will not show up in the exportfs list. This problem is happening in a commercial environment, with a number of very knowledgable developers being effected. If you require us to do any testing, feel free to ask, we will do what we can. my work email: dboyd.ca
I'm seeing the same behavior on our 6.2 system. There seems to be a change from the way nfs worked in previous versions of RedHat. I think that what is happening is this: If a directory is exported and if a different partition of a local disk is mounted on a subdirectory, then that second partition is no longer exported as a subdirectory. In old versions of RH, it was exported.

I have found that the mount command in RH 6.2 will not nfs mount a volume exported from Novell 5.1 NFS. It gets a permission denied or volume not found message. (It works fine on RH 7.0). When I compiled and installed mount-2.10m-6 on RH 6.2, the problem went away.
I'm unable to reproduce this in the current release.
