After rebooting the the NFS server the webservers automatically picked up the NFS mount when the server came back up. I noticed that the NFS mount acted slowly (often generating server not responding/server back messages) and the server would bounce back and forth between high disk usage (100%) and almost none and (oddly enough, this reads correct) low system CPU usage while there's high disk usage and high system CPU while there's low disk usage. unmounting and mounting the mounts on all the clients seemed to fix the issue. Any ideas what's going on? -- Michael Conlen
