Severity: 4-Minor

Symptoms

FQDN nodes and pool members show a status of Green (Available) when the DNS server responds to the FQDN name resolution query with an NXDOMAIN response.

Impact

FQDN nodes and pool members may appear to be Available when no ephemeral nodes/pool members have been created.

Conditions

This occurs when the DNS server returns an NXDOMAIN response for the configured FQDN name.

Workaround

None.

Fix Information

FQDN nodes and pool members show a status of Yellow (Unavailable) when the DNS server responds to the FQDN name resolution query with an NXDOMAIN response. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.
