Insight
Insight
ZFS is a file-system originally developed by Sun Microsystems. The ZFS Intent Log (ZIL) is a mechanism that gathers together in memory transactions of writes, and is flushed onto disk when synchronous semantics is necessary. In the event of crash or power failure, the log is examined and the uncommitted transaction would be replayed to maintain the synchronous semantics. When replaying setattr transaction, the replay code would set the attributes with certain insecure defaults, when the logged transaction did not touch these attributes.
Solution
