Cyril Scetbon edited comment on CASSANDRA-6852 at 3/14/14 8:44 AM: ------------------------------------------------------------------- I don't think the original JIRA can really help me :( I understand that you chose to not repair -pr on a node not storing data for one keyspace. However here is my problem or show me I'm wrong: http://pastebin.com/VrDnWvAu So the incriminated node owns 10.1% of the tokens which seem to be responsible for rows in keyspace ks1. However as ks1 is not replicated to that node, how can I repair it without a FULL REPAIR on all nodes ? At the beginning I thought like [~jjordan] when I read his [comment|https://issues.apache.org/jira/browse/CASSANDRA-5424?focusedCommentId=13673260&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13673260]. However I can see that tokens on the incriminated node (not replicating data for ks1) are referring rows ... I suppose it's what we call primary ranges and if not why do I find ks1's data for those tokens ? was (Author: cscetbon): I don't think the original JIRA can really help me :( I understand that you chose to not repair -pr on a node not storing data for one keyspace.

FYI, a full repair takes almost 20 > hours per node. The matter is that we can't use "repair -pr" anymore for > tokens stored on dc3 concerning keyspaces not replicated. We should have a > way to repair those ranges without doing a FULL REPAIR everywhere -- This message was sent by Atlassian JIRA (v6.2#6252)
