NFS replication & Failover errors
Hi All,
We have been having this problem with NFS failover. Today we suffered an issue which caused our clients to failover to the secondary NFS server. Every time this happens, we get these warnings

The files are read-only and they are the same... is there some checksuming file or state file that could be cleared out during a failover?
Any ideas why NFS thinks they are not the same files?
Were running Solaris 10 X86
