> Remaining Estimate: 0h

> There are the case when we start a checkpoint but not create CP file marker,
> but PageMemory may start to flush dirty pages from checkpoint pages to page
> store. If node crashed at this moment, we can get inconsistency state,
> because we still not write checkpoint marker to disk but already write some
> pages for this checkpoint. If we try to recover from this state we cat get
> any sort of corruption problem. Recovery logic may not recognize that crash
> was during checkpoint because we did not write file marker when we start
> checkpoint but write some pages for this checkpoint.
