This is a 3 node Galera cluster on 3 KVM virtual machines. The errors are constantly printing in the logs, and no node is excluded from receiving the errors. I don't know whether they had always been there or not, but I noticed them after an update. >Does the openstack environment work as expected despite these messages >or do you experience interruptions in the services? The openstack services operate normally, the dashboard is fairly slow, but it always has been. >I would check the network setup first (I have read about loose cables >in different threads...), maybe run some ping tests between the >machines to see if there's anything weird. Since you mention different >services reporting these interruptions this seems like a network issue >to me. The hosts are all networked with bonded 10G SFP+ cables networked via a switch. Pings between the VMs seem fine. If I were to guess, any networking problem would be between the guest and host due to libvirt. Anything that I should be looking for there?
