Yes, you would want to merely modify all the tokens, seed ips, and set auto_bootstrap to true. Stop the service, clear the data at /raid0/cassandra/*, then start each node with 2 minutes in between, along with anything else I may be missing from the docs. I used to have this option, but we deprecated it due to an expanding QA rubric. However, the typical use case for the AMI is something of a more easy, friendly, well-configured developer tool. Once you get to expanding a cluster, that's more of an "advanced" scope than what the AMI was meant to handle. The expanding is also simple enough to where most cases are fairly straight forward. However, the edge cases where you're adding a new datacenter would be a bit tougher to code without some sort of manual intervention either way. Reflector.php's description can be found here: <a href="https://github.com/riptano/ComboAMI/blob/2.2/FILES.md#reflectorphp" rel="nofollow">https://github.com/riptano/ComboAMI/blob/2.2/FILES.md#reflectorphp</a> Tokentool is a script that provides the computation for the tokens when the cluster boots up. Cheers, Joaquin pnegri on "aws ami" http://www.datastax.com/support-forums/topic/aws-ami#post-2936 Wed, 11 Jul 2012 17:36:44 +0000 pnegri 2936@http://www.datastax.com/support-forums/ Hey Joaquin, what do you mean by "In the AWS Management Console, create a cluster with the number of nodes you want add, as described above."? Create a new cluster with a different name from the running one? Stop all, and then reconfigure and join? Wouldnt be better if we could supply our tokens when launching the new AMIs? Something like a manager or a URL to auto assign these? Also, whats the purpose of reflector.php and tokentook? Thank you joaquin on "aws ami" http://www.datastax.com/support-forums/topic/aws-ami#post-2596 Mon, 02 Jul 2012 21:05:52 +0000 joaquin 2596@http://www.datastax.com/support-forums/ I received a forwarded email about your concerns between the 2.1 and 2.2 AMIs. Both AMI's are nearly identical and most of the changes were small edge cases and a complete rewrite for cleaner code. But both are compatible on a higher level. Thanks, Joaquin joaquin on "aws ami" http://www.datastax.com/support-forums/topic/aws-ami#post-2589 Mon, 02 Jul 2012 19:25:14 +0000 joaquin 2589@http://www.datastax.com/support-forums/ Hello, This shouldn't have happened due to this line that ensures new versions will never been installed: <a href="https://github.com/riptano/ComboAMI/blob/2.2/ds2_configure.py#L743" rel="nofollow">https://github.com/riptano/ComboAMI/blob/2.2/ds2_configure.py#L743</a> To remove the node, simple run a <code>nodetool decommission</code> on the node. If this fails, you can kill the node and run a <code>nodetool removetoken</code> that will remove the entire token and any data that may be on the node, so use cautiously. For the full documentation on how to expand an AMI cluster, see: <a href="http://www.datastax.com/docs/1.1/install/expand_ami" rel="nofollow">http://www.datastax.com/docs/1.1/install/expand_ami</a> But do note that you will have to set the <code>--release</code> switch appropriately: <a href="https://github.com/riptano/ComboAMI/blob/2.2/SWITCHES.md" rel="nofollow">https://github.com/riptano/ComboAMI/blob/2.2/SWITCHES.md</a> Thanks, Joaquin denov on "aws ami" http://www.datastax.com/support-forums/topic/aws-ami#post-2588 Mon, 02 Jul 2012 18:57:34 +0000 denov 2588@http://www.datastax.com/support-forums/ somehow after a reboot of my aws datastax 2.1 instance i found that it upgraded cassandra from 1.0.7 to 1.1.1. how do i replace this node? it seem like the ami is only for setting up clusters and not for adding single nodes? thanks, deno thobbs on "Issue starting opscenterd service" http://www.datastax.com/support-forums/topic/issue-starting-opscenterd-service#post-869 Mon, 19 Dec 2011 17:41:59 +0000 thobbs 869@http://www.datastax.com/support-forums/ Just to be clear, the Amazon Linux AMI is not a supported distro for OpsCenter. bonami: It looks like you're using the 64 bit version of the AMI. You'll need to change the steps that nehc gave to be: 1) Install openssl 0.9.8 sudo yum install openssl098e-0.9.8e-17.7.amzn1.x86_64 2) Change to /usr/lib64 and manually create following two symbolic links: sudo ln -s libssl.so.0.9.8e libssl.so.0.9.8 sudo ln -s libcrypto.so.0.9.8e libcrypto.so.0.9.8 Anonymous on "Issue starting opscenterd service" http://www.datastax.com/support-forums/topic/issue-starting-opscenterd-service#post-866 Mon, 19 Dec 2011 08:19:01 +0000 Anonymous 866@http://www.datastax.com/support-forums/ I have followed the steps given by nehc ,but having the same issue in Amazone AMI ./src/lib/python2.6/site-packages:./lib/py:./lib/py-debian/2.6/amd64: Traceback (most recent call last): File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 631, in run runApp(config) File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/scripts/twistd.py", line 23, in runApp _SomeApplicationRunner(config).run() File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 374, in run self.application = self.createOrGetApplication() File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 439, in createOrGetApplication application = getApplication(self.config, passphrase) --- <exception caught here> --- File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/app.py", line 450, in getApplication application = service.loadApplication(filename, style, passphrase) File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/application/service.py", line 400, in loadApplication application = sob.loadValueFromFile(filename, 'application', passphrase) File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/twisted/persisted/sob.py", line 210, in loadValueFromFile exec fileObj in d, d File "bin/start_opscenter.py", line 1, in <module> from opscenterd import opscenterd_tap File "build/lib/python2.6/site-packages/opscenterd/opscenterd_tap.py", line 16, in <module> File "build/lib/python2.6/site-packages/opscenterd/Config.py", line 392, in init_config File "build/lib/python2.6/site-packages/opscenterd/events/plugins/CassandraStore.py", line 12, in <module> File "build/lib/python2.6/site-packages/opscenterd/CassandraService.py", line 17, in <module> File "build/lib/python2.6/site-packages/opscenterd/Cluster.py", line 14, in <module> File "build/lib/python2.6/site-packages/opscenterd/AgentServer.py", line 23, in <module> File "build/lib/python2.6/site-packages/opscenterd/HttpUtils.py", line 10, in <module> File "/usr/share/OpsCenter/opscenter-1.3.1/lib/py-debian/2.6/amd64/OpenSSL/__init__.py", line 11, in <module> import rand, crypto, SSL, tsafe exceptions.ImportError: libssl.so.0.9.8: cannot open shared object file: No such file or directory Failed to load application: libssl.so.0.9.8: cannot open shared object file: No such file or directory Anonymous on "Issue starting opscenterd service" http://www.datastax.com/support-forums/topic/issue-starting-opscenterd-service#post-859 Thu, 15 Dec 2011 19:34:42 +0000 Anonymous 859@http://www.datastax.com/support-forums/ I noticed that this issue was "resolved" at the top. In which version of the OpsCenter was it resolved? I still had the same problem with v1.3.1. But thanks for the posts here for providing clues. Here are steps to fix the problem in AWS Linx AMI: <a href="http://randomizedsort.blogspot.com/2011/12/fixing-libssl-and-libcrypto-errors-in.html" rel="nofollow">http://randomizedsort.blogspot.com/2011/12/fixing-libssl-and-libcrypto-errors-in.html</a> It will help users if the docs can specify the libssl and libcrypto versions required instead of just stating "openssl" like below: <a href="http://www.datastax.com/docs/opscenter/install_opscenter#opscenter-installation-prerequisites" rel="nofollow">http://www.datastax.com/docs/opscenter/install_opscenter#opscenter-installation-prerequisites</a> Thanks.
