NFS Read Only Mount & NFS-failover

[oscaruser at programmer.net]

Folks,

Apparently Solaris has a mechanism for NFS failover, and is described 
in the below URL reference. The key is that the NFS was mounted read 
only & and the files systems have identical files so that the NFS 
client can switch-over seamlessly. We have a similar need, but does 
FBSD support this via NFS at all? If not, is there an alternative (AFS 
or something) that achieves this end goal. Google searches said that 
no, this is not available yet.

Thanks,
OSC
