> >The leases are revoked on reference; not before. Local cache coherency >is not maintained. I'm a little unclear on what you mean by "on reference" Do you mean on a write attempt? It seems to me that if a process on the server machine wants to write to a file which has leases against it, it ought to revoke those leases immediately, or at least when a client attempts to read additional data. > >What kind of clients are you using? > Pentium 133's with 64-128 MB of RAM (if you're wondering about the size of buffer caches). We're setting up a new ISP with the biggest FBSD cluster _I_'ve ever heard of. Unfortunately, we're having a VM problem/crisis (another message on that will follow on the questions list) which may monkeywrench the plans. >Caching NFS is evil. > Yeah. Well, it would be somewhat helpful on our read-only fairly static file systems (like /usr/local), but perhaps the price is too high stability- wise. Eric
