    Just tried the expand-import feature. It worked as in I can issue queries against the newly imported table and the data appears to be correct, but my log is filled with tons of errors like:

    090723 14:39:50 InnoDB: Error: space id and page n:o stored in the page
    InnoDB: read in are 13016:7746928, should be 13364:7746928!

    Is XtraDB usable as MySQL Cluster data node?
    And if the engine is not usable (but ndb), could there be some general performance gains, i.e. caused by some of the (kernel) patches?
