Josh McKenzie updated CASSANDRA-16879: -------------------------------------- Status: In Progress (was: Patch Available) > Verify correct ownership of attached locations on disk at C* startup > -------------------------------------------------------------------- > > Key: CASSANDRA-16879 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16879 > Project: Cassandra > Issue Type: Improvement > Components: Local/Startup and Shutdown > Reporter: Josh McKenzie > Assignee: Josh McKenzie > Priority: Normal > Fix For: 4.x > > > There's two primary things related to startup and disk ownership we should > mitigate. > First, an instance can come up with an incorrectly mounted volume attached as > its configured data directory. This causes the wrong system tables to be > read. If the instance which was previously using the volume is also down, its > token could be taken over by the instance coming up. > Secondly, in a JBOD setup, the non-system keyspaces may reside on a separate > volume to the system tables. In this scenario, we need to ensure that all > directories belong to the same instance, and that as the instance starts up > it can access all the directories it expects to be able to. (including data, > commit log, hints and saved cache dirs) > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
