Hello All, My Fuel version is 7.0, with 3 controllers and 11 computes. This cluster has been running for a while now and recently, due to an Internet connectivity issue, a time sync issue was noted. Even after fixing this and time being in sync now(after a rolling reboot of all controller nodes,) the health check is reporting mysql, galera related issues as shown in the screenshots below. Can somebody please guide me on how to start debugging and fixing these issues? Still a beginner with Openstack :) ps: We saw all compute nodes' nova-compute and one controller's nova-conductor service going down after the NTP change. Except for these services being restarted, no other action has been done on the cluster. Thanks in Advance, Raja. -- :^) -------------- next part -------------- An HTML attachment was scrubbed...
