I'm running the command to repair the broken table. The documents seem very reassuring that everything will be o.k. in a situation like this.
But the command is taking a long time to run. As a precautionary measure, I've turned off the website completely during the rebuild, so that we don't spook the database while I'm repairing the table.
It's a big table. I guess it makes sense for the command to take a long time.
