All of the following is assuming you're using Linux. I'm using RHEL 6.3 to mount an NFSv3 based device using autofs.
I should have added that the issue for me was that I had specified the wrong block size values for the rsize/wsize parameters in the autofs mount configuration for the device I was mounting. I was operating in the mistaken belief that the larger the value for these parameters the better. Therefore I set their values to be 256K (in bytes). Problems with the message store followed. What I should have done, and ended up doing, was rather than guess the value of the device's block size was to determine the device's _actual_ block size. You can either ask the administrator for the device what its block size is or use the stat command. If you really want to play it safe you could always use the default block size for a device that supports NFSv3 which is quite conservative at 8192 bytes (I think - look it up). However, if the device you're mounting can support larger block sizes then the stat command is how you would find that out. First, mount the device using a _very_ conservative block size value, say 1024 bytes. Second, run the stat command on the mount point to see what the device's block size actually is. It might be the default 8192 or it could be larger. Either way you'll know. Here's an example. Say your local mount point is /NFS then the stat command to use is: stat -f /NFS The output should look something like: File: "/NFS" ID: 0 Namelen: 255 Type: nfs Block size: 32768 Fundamental block size: 32768 Blocks: Total: 330424288 Free: 178080429 Available: 178080429 Inodes: Total: 257949694 Free: 246974355 The output indicates the block size in bytes (32768) for the device. This is the value that should be plugged into the rsize/wsize parameters for the mount's definition. I hope this helps.
