Thanks to everyone who contributed advice to my question about how to distribute a Lucene index across a cluster. I'm about to start on the implementation and I wanted to clarify something about using NFS that Chris wrote about above. There are many warnings about indexing on an NFS file system, but is it safe to have a single node index, while the other nodes use the file system in read-only mode? On a related note, our software is cross-platform and needs to work on Windows as well. Are there any problems known problems having a read-only index shared over SMB? Using a shared file system is preferable to me because it's easier, but if it's necessary I will write the code to copy the index to each node.
