Just had this problem in Ubuntu 12.04. Setting nfsvers=3 in fstab solved this for me.
As enedene I thought I was using NFS 4 until I saw the /etc/exports file comments and realised I also use NFS3 Both the server and the client are running Ubuntu 12.04. (They were installed as 12.04 beta 2 but are now updated to 12.04) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/891825 Title: NFS client doesn't mount or mounts slow on startup on 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/891825/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
