1. Switching to InnoDB But how?

2. Transactions Crash recovery Table 'node_revisions' is marked as crashed and should be repaired

4. > ALTER TABLE tablename ENGINE=InnoDB;

5. mysql_convert_table_format --type=InnoDB databasename

7. Buffer pool Tablespace Transaction log

9. innodb_flush_method = O_DIRECT (on Linux)
