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. -- This message was sent by Atlassian Jira (v8.3.2#803003)
