[Kernel-packages] [Bug 1327563] Re: Long delay when mounting NFS shares
Unfortunately no, I can still reproduce it on 3.13.0-32-generic. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1327563 Title: Long delay when mounting NFS shares Status in “linux” package in Ubuntu: Confirmed Bug description: Summary: After upgrading the kernel on Ubuntu 14.04 to 3.13.0-29-generic I found that it can take a considerably longer amount of time to mount NFS shares. How to reproduce: 1. Install Ubuntu 14.04 on two machines. A minimal server install should be fine. One will act as a server, the other as a client. 2. Upgrade the kernel on the client machine to at least 3.13.0-27-generic. 3. Install the nfs-kernel-server package on the server. 4. Add a directory to /etc/exports and run service nfs-kernel-server start. 5. Install the nfs-common package on the client. 6. Attempt to mount the shared directory on the client. Expected result: The shared directory should be mounted on the client more or less immediately. Actual result: The mount command hangs and eventually completes. In this test case it takes 16 seconds consistently. On a production machine where the problem was first discovered the time is considerably longer and essentially makes it impossible to mount NFS shares.

I have installed and tested all three kernels (v3.13.10, v3.13.11.1 and v3.13.11.2) by rebooting and selecting the kernel version at the grub menu.

How to reproduce: 1. Install Ubuntu 14.04 on two machines. A minimal server install should be fine. One will act as a server, the other as a client. 2. Upgrade the kernel on the client machine to at least 3.13.0-27-generic. 3. Install the nfs-kernel-server package on the server. 4.

Expected result: The shared directory should be mounted on the client more or less immediately. Actual result: The mount command hangs and eventually completes. In this test case it takes 16 seconds consistently.

** Description changed: Summary: After upgrading the kernel on Ubuntu 14.04 to 3.13.0-29-generic I found - that it can take a considerable longer amount of time to mount NFS + that it can take a considerably longer amount of time to mount NFS shares. How to reproduce: 1. Install Ubuntu 14.04 on two machines. A minimal server install should be fine. One will act as a server, the other as a client. 2. Upgrade the kernel on the client machine to at least 3.13.0-27-generic. 3. Install the nfs-kernel-server package on the server. 4. Add a directory to /etc/exports and run service nfs-kernel-server start. 5. Install the nfs-common package on the client. 6. Attempt to mount the shared directory on the client. Expected result: The shared directory should be mounted on the client more or less immediately. Actual result: The mount command hangs and eventually completes. In this test case it takes 16 seconds consistently. On a production machine where the problem was first discovered the time is considerably longer and essentially makes it impossible to mount NFS shares. Regression: I have been able to reproduce the problem on clients running Linux 3.13.0-27-generic and later. The problem is not reproducible on clients running Linux 3.13.0-24-generic. The problem is reproducible no matter which kernel version is used on the server.
