Subject [jira] [Commented] (CASSANDRA-3483) Support bringing up a new datacenter to existing cluster without repair
Date Mon, 05 Dec 2011 16:10:43 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3483?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162857#comment-13162857
] 

Jeremiah Jordan commented on CASSANDRA-3483:
--------------------------------------------

Once this option is in, is this the procedure for running rebuild (with 4 changed to 'rebuild
dc1')?

{quote}
1. strategy options dc2:0
2. bring up new nodes in dc2 with auto_bootstrap off and token set
3. set strategy options dc2:3
4. run 'rebuild' on each node in dc2
{quote}

Do we need to stagger issuing the rebuild commands or can they be run all at once?

> Was talking to Brandon in irc, and we ran into a case where we want to bring up a new
DC to an existing cluster. He suggested from jbellis the way to do it currently was set strategy
options of dc2:0, then add the nodes. After the nodes are up, change the RF of dc2, and run
repair. 
> I'd like to avoid a repair as it runs AES and is a bit more intense than how bootstrap
works currently by just streaming ranges from the SSTables. Would it be possible to improve
this functionality (adding a new DC to existing cluster) than the proposed method? We'd be
happy to do a patch if we got some input on the best way to go about it.
