Hi folks, I am running Whezzy on my NFServer and the NFS clients. Kernel is Linux nfs-home.example.com 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt11-1~bpo70+1 (2015-06-08) x86_64 GNU/Linux Problem: Sometimes a client cannot write to /home via NFS anymore. The error message in kern.log on the client says Jul 30 15:53:57 dpcl082 kernel: [2880660.867248] NFS: Server nfs-home reports our clientid is in use Jul 30 15:53:57 dpcl082 kernel: [2880660.867254] NFS: state manager: lease expired failed on NFSv4 server nfs-home with Jul 30 15:54:54 dpcl082 kernel: [2880717.424872] NFS: Server nfs-home reports our clientid is in use Jul 30 15:54:54 dpcl082 kernel: [2880717.424878] NFS: state manager: lease expired failed on NFSv4 server nfs-home with Jul 30 15:55:01 dpcl082 kernel: [2880724.526741] NFS: Server nfs-home reports our clientid is in use Jul 30 15:55:01 dpcl082 kernel: [2880724.526748] NFS: state manager: lease expired failed on NFSv4 server nfs-home with : : I have to umount and mount /home to get read access again. The kern.log on the server doesn't mention this incident. Since I saw "NFSv4.1: Fix client id trunking on Linux" introduced with 3.16.7-ckt7-1 I wonder if this rings a bell somewhere? By now I saw this problem 4 times within the last week. There are more than 100 NFS clients, using a static mount of /home , i.e. the problem is hard to reproduce. Every helpful comment is highly appreciated. Regards Harri
