             Summary: WAL in LOG_ONLY mode doesn't execute fsync on checkpoint 
                 Key: IGNITE-7754
             Project: Ignite
          Issue Type: Bug
            Reporter: Ilya Lantukh
            Assignee: Ilya Lantukh

On checkpoint begin method IgniteWriteAheadLogManager.fsync(WALPointer ptr) 
will be called, but it won't actually perform fsync because mode isn't FSYNC. 
It might lead to LFS corruption if OS or hardware failed until checkpoint had 
been finished.
