PowerVC - Swift configuration may impact Server function

Troubleshooting


Problem

PowerVC 2.0.2 may report that managed compute resources are in ERROR status.

Symptom

The PowerVC Web interface may report that nova compute systems are in ERROR status after installing PowerVC 2.0.2.

Cause

This issue will be seen if PowerVC configures the Swift service using a name which is not resolvable within the SSL certificate of the PowerVC domain. The PowerVC self-signed certificate includes the IP address and Virtual IP address of each PowerVC node, as well as the fully qualified domain name (FQDN).

If PowerVC configures the Swift service with the short name instead of the FQDN, an error will be seen.

Environment

PowerVC 2.0.2 

Diagnosing The Problem

Review the nova compute log in /var/log/nova for the host(s) which report ERROR from the PowerVC UI. You may find errors from Swift such as:

CertificateError: hostname 'hostname' doesn't match either of '9.153.164.14', '9.153.164.15', 'FQDN of VIP'

An error of this type is evidence of misconfiguration.



Resolving The Problem

Edit the /etc/swift/proxy-server.conf configuration file, and find the line that contains "www_authenticate_uri". Replace the short name with the correct FQDN of the node.

For example,

www_authenticate_uri = https://PowerVC-node1:5000/v3

would be replaced with the FQDN of node1:

www_authenticate_uri = https://PowerVC-node1.acme.com:5000/v3

where acme.com is your environment's FQDN.
