File Storage CREATE API Operations Fail

File Storage API resource create operations such as createFileSystem fail to create resources.

Cause: High volume can cause API calls to fail. If you haven't specified retry in your request, the operation isn't tried again, and the resource isn't created.

Solution: Retry the API operation. Use the opc-retry-token header in the create resource request. For example: 
POST /20171215/fileSystems
Host: filestorage.us-phoenix-1.oraclecloud.com
opc-retry-token: 239787fs987
<authorization and other headers>
{
  "availabilityDomain" : "pWEh:PHX-AD-2",
  "compartmentId" : "ocid1.compartment.oc1..<unique_ID>",
  "displayName" : "media-files-1"
}
