I create a cluster using this guide http://docs.openstack.org/developer/sahara/devref/quickstart.html but it stays in waiting state and after some time goes into error. In sahara logs I see the following:
2015-07-17 09:31:20.510 DEBUG sahara.service.engine [req-c4feb0e8-8f35-4634-b939-5a51d340f2a2 demo demo] [instance: d3571fd3-0f20-4c39-bfbc-239c9b5f1413, cluster: b992
81a7-d38e-4d4e-adf3-3774261fd8ee] Can't login to node, IP: 172.24.4.6, reason error: [Errno 110] Connection timed out
Seems it can not ssh to the instances since port 22 isn't opened. 'nova list' and 'nova secgroup-list' show 3 active instances and 3 security groups. But these groups are not assigned to the instances. After I assign them manually the cluster turns to active state.
I tested it on devstack (master branch) using nova-net.
Please let me know if I can provide any further information.
we have discussed this issue and we are wondering if the automatic security groups were turned on for this test?
we are having some difficulty assessing the proper response as this could be seen as an operator/
also, there is another possibility here, and that is for sahara to check whether the proper security groups are in place for ssh to occur.
regardless, we would like to know a little more about the setup. in specific, were automatic security groups enabled?
