Omid Aladini created CASSANDRA-5195: ---------------------------------------
Summary: Offline scrub does not migrate the directory structure on migration from 1.0.x to 1.1.x and causes the keyspace to disappear Key: CASSANDRA-5195 URL: https://issues.apache.org/jira/browse/CASSANDRA-5195 Project: Cassandra Issue Type: Bug Components: Core Affects Versions: 1.1.9 Reporter: Omid Aladini Due to CASSANDRA-4411, upon migration from 1.0.x to 1.1.x containing LCS-compacted sstables, an offline scrub should be run before Cassandra 1.1.x is started. But Cassandra 1.1.x uses a new directory structure (CASSANDRA-2749) that offline scrubber doesn't detect or try to migrate. How to reproduce: 1- Run cassandra 1.0.12. 2- Run stress tool, let Cassandra flush Keyspace1 or flush manually. 3- Stop cassandra 1.0.12 4- Run ./bin/sstablescrub Keyspace1 Standard1 which returns "Unknown keyspace/columnFamily Keyspace1.Standard1" and notice the data directory isn't migrated. 5- Run cassandra 1.1.9. Keyspace1 doesn't get loaded and Cassandra doesn't try to migrate the directory structure. Also commitlog entries get skipped: "Skipped XXXXX mutations from unknown (probably removed) CF with id 1000" Without the unsuccessful step 4, Cassandra 1.1.9 loads and migrates the Keyspace correctly. -- This message is automatically generated by JIRA.
