Your problem does not sound as though it is directly a consequence of NFS, not if you can mount the exported drive or partition. I am the 'tech guy' for the Linux server, however only the AIX sys admins have root access to AIX servers (one which I am using as an NFS client). You might want to do a man nfsstat (I have found nfsstat -m particularly useful in this regard). It sounds as though you have a connectivity problem.

Re: [expert] NFS LM8.1 server, AIX client problems
Laurent, Got some problems at work with an NFS server running on Linux (was kernel 2.2.18), and AIX NFS clients (4.2, 4.3.1 and 4.3.3). On AIX clients, we run as root: nfso -o nfs_use_reserved_ports=1 Then, we were able to mount the filesystems from our Linux box... I remember that we call our IBM support to have this information. I just checked, and this was done by the tech guys for the AIX client. I added the nfs_use_reserved_ports=1 to /etc/rc.uc.posttcpip so that he's be able to do his mounting... With this I was able to mount, however the problem is still that I can't copy the contents of the NFS mounted CD onto the local AIX client. Thanks... Dan.

Daniel Woods wrote: I have not tried soft mount because the NFS how-to recommends to never use it, otherwise you risk file corruption. I have used a soft mount many times with both AIX and Solaris over the years. It has not ever corrupted any file. The main thing that a soft mount does is to not make an entry in /etc/filesystems on AIX. If you ever reboot your AIX machine, and the Linux NFS service is not available, you will find that your boot process has just went to shit on you while it attempts to read /etc/filesystem and mount a non-existent export. You could give the soft mount a try, just to see what happens. One 2 min experiment should not doosh the system -- J.
