Andres de la Peña commented on CASSANDRA-12519:
-----------------------------------------------
The error mentioned in the description and in the two tickets that this is a
duplicate of is about the releveling itself, and I haven't been able to
reproduce it in 4.0.
However, the error mentioned in the last comment is different. This new error
consists on a validation error in the transaction log, thrown when running
{{sstableoflinerelevel}}, at the moment of [listing the
sstables|https://github.com/apache/cassandra/blob/cassandra-4.0.0/src/java/org/apache/cassandra/tools/SSTableOfflineRelevel.java#L104].
I haven't been able to reproduce this new type of failure in 3.0 and 3.11,
although it can be reproduced in 4.0 with a few thousands of rounds in the
multiplexer.
I suspect that somehow the corruption happens in the previous call to
{{sstablelevelreset}}, so {{sstableoflinerelevel}} hits it before it actually
starts the releveling. Indeed, the failure can be reproduced by just calling
{{sstablelevelreset}} twice, without using {{sstableoflinerelevel}}.
