Hello I'm looking for an implementation of HA-NFS (Higly Available Network File Server) on top of a BSD. This is an extension of the standard NFS server implementation which roughly consists of having a secondary NFS server on the net which is able to (1) take the IP address of the failed primary, (2) re-mount the filesystem (requires an underlying disk mirroring), (3) update its cache of non-idempotent operations got (by msg checkpoint, disk storage or...) from the primary. This is totaly transparent for an NFS client, NFS protocol on the wire is unchanged. The original paper for it is a Usenix-91 (HA-NFS Anuman Bhide and all). Do you have a pointer for an implementation of this in the BSD environment ?
