> 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.
