How can I repair a TokuDB table?
TokuDB does not support the repair table command, just like InnoDB, so you can't repair the table in question. If you don't have a backup or slave to pull from the best you can do is select the rows from the readable portion of the table itself. I'd recommend using "select * from table_name where table_pk &lt; ? into ;" and "select * from table_name where table_pk > ? into ;". You'll need to experiment with the ? for each statement, because once you read the damaged part of the file the server will crash.
