    Hi Aleksander,
    These packages still have the dependency failure/conflict I filed here:

    It somewhat defeats the purpose of having a CentOS/RHEL package if the package is going to cause a dependency conflict with things in base.

    Any idea when these will be published at ?

    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!

    can you post all your steps to bug report on Launchpad ? Thanks!

  5. 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?

  6. A similar question has been asked on Stack Overflow, maybe you guys can give a usable answer:
