> The block size should be 185818648 in the first CloseOp. When truncate is
> used, the block size becomes 185818644. The CloseOp/TruncateOp/CloseOp is
> synchronized to the JournalNode in the same batch. The block used by CloseOp
> twice is the same instance, which causes the first CloseOp has wrong block
> size. When SNN rolling Editlog, TruncateOp does not make the file to the
> UnderConstruction state. Then, when the second CloseOp is executed, the file
> is not in the UnderConstruction state, and SNN crashes.
