Hi Hannu, I remember there have been discussions about this in the past. Most probably there is already a JIRA for this. I roughly remember a consense like that: - Default behaviour should remain - It should be configurable to the needs and preferences of the DBA - It should at least spit out errors in the logs
... of course it would be even better to have the underlying issue fixed that commit logs should not be corrupt but I remember that this is not so easy due to some "architectural implications" of Cassandra. IIRC Ed Capriolo posted something related to that some months ago. For a quick fix, I'd recommend: - Delete the affected log file - Start the node - Run a full-range (not -pr) repair on that node 2017-07-07 10:57 GMT+02:00 Hannu Kröger <hkro...@gmail.com>: > Hello, > > We had a test server crashing for some reason (not related to Cassandra > probably) and now when trying to start cassandra, it gives following error: > > ERROR [main] 2017-07-06 09:29:56,140 JVMStabilityInspector.java:82 - > Exiting due to error while processing commit log during initialization. > org.apache.cassandra.db.commitlog.CommitLogReadHandler$CommitLogReadException: > Mutation checksum failure at 24240116 in Next section at 24239690 in > CommitLog-6-1498576271195.log > at org.apache.cassandra.db.commitlog.CommitLogReader. > readSection(CommitLogReader.java:332) [apache-cassandra-3.10.jar:3.10] > at > org.apache.cassandra.db.commitlog.CommitLogReader.readCommitLogSegment(CommitLogReader.java:201) > [apache-cassandra-3.10.jar:3.10] > at org.apache.cassandra.db.commitlog.CommitLogReader. > readAllFiles(CommitLogReader.java:84) [apache-cassandra-3.10.jar:3.10] > at org.apache.cassandra.db.commitlog.CommitLogReplayer. > replayFiles(CommitLogReplayer.java:140) [apache-cassandra-3.10.jar:3.10] > at org.apache.cassandra.db.commitlog.CommitLog. > recoverFiles(CommitLog.java:177) [apache-cassandra-3.10.jar:3.10] > at > org.apache.cassandra.db.commitlog.CommitLog.recoverSegmentsOnDisk(CommitLog.java:158) > [apache-cassandra-3.10.jar:3.10] > at > org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:326) > [apache-cassandra-3.10.jar:3.10] > at > org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:601) > [apache-cassandra-3.10.jar:3.10] > at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:735) > [apache-cassandra-3.10.jar:3.10] > > Shouldn’t Cassandra tolerate this situation? > > Of course we can delete commit logs and life goes on.
