We currently have a 3 node cluster set up, and it is working great, I would like to add another 2 nodes to our setup, but it consistently fails. The Percona setup uses 2 sites, locally, we currently have 2 nodes, and our colocation we have a single node (trying to add more) the current node at the colo has been running for 3 months no issue.
Just wondering if ANYONE has an idea, all nodes have been updated to the same version software, selinux is off, firewalls are all off, can telnet to correct ports. This one has me pulling my hair out. I am going to try to add another node to my location here and see if the same thing happens, but I really need to have these other nodes set up and functioning for the new website rollout.
Thanks in advance!
