I realized that replication via shared FS (a DFS, or an NFS mount, etc) needs improvement to be able to handle failover. Each SM instance has to sort of 'own' its data to be able to sync the various operations on it. Need a way to move ownership between SM instances. I think I have a relatively light-weight way to do this that isn't too ugly, will start coding it up. |
