Failover using wackamole?

["Vsevolod (Simon) Ilyushchenko" <simonf@cshl.edu>]

Hi,

I had this neat idea that NFS failover of read-only filesystems can be 
achieved using wackamole (floating IP adresses providing very simple 
HA). This did not work with NFS 3 because the filehandles are different 
on the primary and the secondary servers, so I was getting a "stale NFS 
filehandle" error after the failover.

I tried this using NFS 4 nfs-utils-1.0.6-52 from FC3 updates. However, 
it still failed with the following error:
	ls: reading directory a: Input/output error
and this in the error log on the client:
	kernel: RPC: garbage, exit EIO

Is this a bug or a feature?

Thanks,
Simon
