Tasks are slow or stall out in Cloud Director multi cell installation

By

Recently, I was troubleshooting a VCD 10.4 installation with three cells which experienced very slow response times during operations such as Power on/off a VM.

Looking throw the log files soon revealed messages such as:

ERROR | ActiveMQ BrokerService[] Task-15 | TransportConnector | Could not accept connection from tcp://:47990 : javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown

To resolve this issue, we’ve checked if the certificate is expired by running the following command on one of the cells:

/opt/vmware/vcloud-director/bin/cell-management-tool jms-certificates --status

The following part of the command result shows, that all of the 3 cells didn’t had a valid certificate:

To generate new certificates, we’ve run the command:

/opt/vmware/vcloud-director/bin/cell-management-tool jms-certificates --certgen --force

Afterwards, we restarted all cells:

service vmware-vcd restart

This fixed the issue in this environment.

While checking the cluster in the resource vCenter Server (version 7.x), the following error was shown in the vSphere Client:

“vSphere DRS functionality was impacted due to unhealthy state vSphere Cluster Services caused by the unavailability of vSphere Cluster Service VMs. vSphere Cluster Service VMs are required to maintain the health of vSphere DRS”
