Isn't it true that reindex's behavior is to simply, quietly delete the
index? that was reported by someone when all this was going around
before. I wrote my own reindex script that basically (in a single
transaction) grabbed the definition of the index, dropped said index, then
recreated it, then committed the transaction, so that if it failed for any
reason, the old index was still there.
If reindex does "lose" the index on failure then we need to look at
changing how it works before we recommend it as a "daily maintenance
routine".
