Hello everyone!
I came across the fact that if we started a node with WAL archiving disabled, and then poured data there and there were more than DataStorageConfiguration#walSegments, then when we try to restart the node with WAL archiving enabled, there will be an error. Workaround for this error: Move all segments to WAL archive directory (include consistentId directory) as they are except the last one. Last one rename as index % DataStorageConfiguration#walSegments. I think that this workaround should be done automatically, which I want to do in https://issues.apache.org/jira/browse/IGNITE-13877
