-------------------------------------------
Summary: Potentially pds corruption on a failed node during
checkpoint
Key: IGNITE-12128
URL: https://issues.apache.org/jira/browse/IGNITE-12128
Project: Ignite
Issue Type: Bug
Reporter: Dmitriy Govorukhin
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.
