I see.. Ok thanks Bulman.<br /> Since the node was restarted recently, It might take some time to replicate &amp; fill it up. </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1117 Thu, 09 Feb 2012 19:24:23 +0000 mbulman 1117@http://www.datastax.com/support-forums/ <p>The size of the node represents how much data the node is holding. It's possible the small node is not getting that data from the agent, or that your ring is actually unbalanced. You can verify in the "List View" under "Cluster". </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1116 Thu, 09 Feb 2012 19:22:53 +0000 Anonymous 1116@http://www.datastax.com/support-forums/ <p>I clicked on the Install agents on the UI, which got the agents back running. I guess the command does the same.</p> <p>This question may sound silly, does the size of the node in the Ring View matter?? because one of the node looks very small, whereas the others look healthy, plump &amp; green :) </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1111 Thu, 09 Feb 2012 18:26:02 +0000 mbulman 1111@http://www.datastax.com/support-forums/ <p>It looks like the agent service is not registered to run on startup by default. We're going to work to fix this in a future version of OpsCenter.</p> <p>In the meantime, if you run <code>update-rc.d opscenter-agent defaults</code> on each of your nodes, that should fix your issue. </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1108 Thu, 09 Feb 2012 02:20:17 +0000 Anonymous 1108@http://www.datastax.com/support-forums/ <p>Yes, the agent did not run. Could you pls check it on your end and confirm? </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1107 Thu, 09 Feb 2012 02:10:45 +0000 mbulman 1107@http://www.datastax.com/support-forums/ <p>If you restart a node, is that agent no longer running? </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1102 Wed, 08 Feb 2012 22:27:51 +0000 Anonymous 1102@http://www.datastax.com/support-forums/ <p>Actually Bulman, I did install via your steps given here.

If you installed via a tarball/manually, you will need to handle that process on your own.</p> <p>INFO is just the default log level we use for opscenterd and the agents. If you'd like to change to DEBUG to get more information, you are more than welcome. </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1100 Wed, 08 Feb 2012 19:44:10 +0000 Anonymous 1100@http://www.datastax.com/support-forums/ <p>Yes, you were right. The agent in one of the node was down. Fixed it.<br /> Wondering, what causes this to happen? Does restarting one of the node does not automatically start up the agent?</p> <p>Also I noticed the conf file in the agent is set to INFO, Should it didn't set to DEBUG to catch more logging of failing nodes/Node reported as down?(This happened twice now :(</p> <p>log4j.rootLogger=INFO,R</p> <p>Thanks Bulman! </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1099 Wed, 08 Feb 2012 19:16:57 +0000 mbulman 1099@http://www.datastax.com/support-forums/ <p>It sounds like either the agent or cassandra itself is down. Can you check the opscenterd.log and opscenter-agent.log for any errors? </p> http://www.datastax.com/support-forums/topic/view-replication-error#post-1098 Wed, 08 Feb 2012 18:33:50 +0000 Anonymous 1098@http://www.datastax.com/support-forums/ <p>Hi,</p> <p>I am not able to see "View replication" on one of the nodes in the Ring View.<br /> I get this error message.</p> <p><code>Error loading replication information: Failed query to <a href="https://10.68.13.222:61621/cluster/range-list?keyspace=Keyspace1" rel="nofollow">https://10.68.13.222:61621/cluster/range-list?keyspace=Keyspace1</a> : Connection was refused by other side: 111: Connection refused.</code></p> <p>What needs to be fixed?</p> <p>Thanks,<br /> Nish </p>
