Omid Aladini updated CASSANDRA-5195: ------------------------------------ Attachment: 5195.patch I tried to fix the issue in offline-scrub but the patch doesn't fully fix the issue. Cassandra 1.1.9 with this patch only loads the migrated keyspaces after 2nd restart after offine-scrub has applies the migration. > 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 > Fix For: 1.1.9 > > Attachments: 5195.patch > > > 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.
