: machine or human error can sometimes unmount the file system. This causes : Solr to write index files to a different area from the index I am using.
can you clarify what you mean by this? Solr will only ever write to the data dir you configure it with. if the parent dir (or volume) doesn't exist, it should fail and refuse to write anything -- there's no reason why it should just start writing index files to some different directory. But for the record: i heartily agree with walter: don't use remote disk for your index. you can always use the backup scripts to bulk copy the index onto remote disk if that's how you want to distrubute or backup the index, but your life is going to be a lot easier if Solr is working with a local filesystem. -Hoss
