What are your mount options? Have you considered using the automounter (or are you already)?

I typically find NFS bliss if I stick with a client and server in the same series as follows: - 2.2.18+ (or early 2.2.x with Trond+Higgen, thank you SGI!) - 2.4.9 or earlier (VM #1) - 2.4.10-2.2.18 (VM #2) - 2.4.21 or later (much better NFS client IMHO) - 2.6.x or later (thank you Sun!) I always have issues if I start using one series of Linux NFS clients with another series of Linux NFS servers, etc... In your case, your server is 2.6.x, and your clients are 2.4.18, maybe 2.4.21+. Those 2.4.19 and 2.4.20 releases were "less than fun" when it came to the Linux NFS client, especially when not connecting to a NFS server of the same series. -- Bryan J.
