   thanks for your reply. yes, an entry log only belongs to one directory, but the data of one journal file will put in different entry log when there are have different directory, when one entry log flush and advanced the last mark, but the some data are put in another entry log may be not persisted. if this happen many times, gc remove the journal file when it reach the size limit or log number limit, the journal will be deleted, but now some data maybe not persisted, when crash, it maybe lost the data. The problem is the data in the journal file before check-pointed mark not only are put in only one entry log.
