MySQL 5.1 does not support the statements CHECK TABLE, OPTIMIZE TABLE, ANALYZE TABLE, or REPAIR TABLE for partitioned tables. However, there are alternatives available for performing partitioning maintenance tasks.

Beginning with MySQL 5.1.5, you can rebuild partitions using ALTER TABLE ... REBUILD PARTITION, which has the same effect as dropping all records stored in the partition, then reinserting them. This can be useful for purposes of defragmentation. You can rebuild a one or more partitions belonging to the same table at one time using this statement, as shown in these examples:

ALTER TABLE t1 REBUILD PARTITION p1;
ALTER TABLE t1 REBUILD PARTITION p0, p2;

Executing the first statement rebuilds the partition named p1 from the table t1. Performing the second statement rebuilds partitions p0 and p2 from table t1.

ALTER TABLE ... REORGANIZE PARTITION also causes partition files to be rebuilt.
