2018-08-30 10:52:34 -0500 answered a question sctp load balancer I was extensively researching this option and came to a conclusion that OpenStack doesn't natively support routing of SCTP headers. You will need to use third party solutions such as GRE tunneling or L2TP, likely with OvS. Overlay is the only option unfortunately. You can establish a master GRE node and from there relay other tunnels towards machines that you need. Also you can do it with VPN as well, that if you need some sort of encryption (or IPsec). 2017-07-07 03:06:08 -0500 asked a question OpenStack deployment fails with message "Failed tasks: Task[primary-database/16]" This happens at the controller node. I have 3 controller nodes, 10 compute nodes, one ceilometer, 6 storage and one monitor node. I have tried to delete each of the controller nodes and try to see if the error persists, and whenever I delete the next controller node - still the same error is reported on one of the others. In the end I tried with one controller node, still the error is the same. Tried to troubleshoot this problem with no luck so far. If anyone has encountered something similar, please share your opinions and experiences. 2017-07-06 13:23:08 ERR (/Stage[main]/Osnailyfacter::Database::Database_backend_wait/Osnailyfacter::Wait_for_backend[mysql]/Haproxy_backend_status[mysql]) /usr/bin/puppet:8:in
