    Unaligned AIO/DIO warnings

    Rich Vibeskowski Newbie

      My servers running HornetQ are logging:  "EXT4-fs (dm-0): Unaligned AIO/DIO on inode 393278 by java; performance will be poor."

      They are physical servers running CentOS 6.2.

      The block size on the drives are 4096.

      But it looks like the libHornetQLibAIO.so has ALIGNMENT set to 512 in JAIODatatypes.h.

      Seems to be the same for both HornetQ versions 2.3.3 and 2.4.0.

       

      I've been looking around for options, but the best I've gotten so far is to use NIO instead.

      Has anyone tried anything else to resolve this?
