I saw a 100X slowdown running with indexes on NFS. I don't understand going through a lot of effort with unsupported configurations just to share an index. Local disk is cheap, the snapshot stuff works well, and local discs avoid a single point of failure.
The testing time to make a shared index work with each new release of Solr is almost certainly more expensive than buying local disc. The single point of failure is real issue. I've seen two discs fail on one RAID. When that happens, you've lost all of your search for hours or days. Finally, how do you tell Solr that the index has changed and it needs a new Searcher? Normally, that is a commit, but you don't want to commit from a read-only Solr. wunder On 2/26/08 10:17 AM, "Matthew Runo" <[EMAIL PROTECTED]> wrote: > I hope so.
