Creating the TDS Configuration Catalog

Duplicate path(s)

If you accidentally use the same path in more than one data root, you will get an error in catalog.

  <datasetRoot path="testdup" location="C:/data/" />
  <datasetScan name="duplicate path" path="testdup" location="/home/workshop/data/" serviceName="dodsServer" />

In https://localhost:8443/thredds/content/logs/catalogErrors.log:
  **Error: already have dataRoot =<testdup>  mapped to directory= <C:/data/> wanted to map to=</home/workshop/data/> in catalog

Data directory doesnt exist

   <datasetRoot path="sage" location="C:/data/notexist/" />

In https://localhost:8443/thredds/content/logs/catalogErrors.log:
  **Error: Data Root =sage directory= <C:/data/notexist/> does not exist

DatasetScan has missing or invalid service

  <datasetScan name="bad service name" path="segundo" location="C:/data/" serviceName="badd" />
  <datasetScan name="no service name" path="tertiary" location="C:/data/" />

In https://localhost:8443/thredds/content/logs/catalogErrors.log:
  **Error: DatasetScan (Top Dataset/bad service name ): must have a default service
  **Error: DatasetScan (Top Dataset/no service name): must have a default service
