ZONE_RULE_TOO_FEW_ZONES_CWOBJ2430=CWOBJ2430E: The zoneRule {0} contains an insufficient number of zones ({1}) for the number of shardMapping entries ({2}) using zoneRule {0}.
Explanation
If a zoneRule contains more than one zone, it must have at least as many zones as shardMappings that make use of the zoneRule.
User response
Add zones to the zoneRule or move shardMappings to different zoneRules. See the Using zones for replica placement section in the information center for more information on zone rules.
