In my post to NFS I decribed how to create and attach a NFS folder.
Last week a colleague asked me to double check the version of this NS folder on the client. It turns out, that it was NFS3 only and not NFS4.
Interestingly this depends on the file permissions of the parent folder. The parend folder has to be read- and executable for others.
myAppServer1 – Server
chmod o+rx /app/myApp exportfs -r exportfs -s
myAppServer2 – Client
umount /app/myApp/uploads mount /app/myApp/uploads mount -> myAppServer1.mynetwork.net:/app/myApp/uploads on /misc/myapp_uploads type nfs4
