Content Package Error

Within the app-ca.log, an error similar to the following appears:
ERROR 2018-04-13 16:07:41,421 [http-nio-14001-exec-11] pagebuilder.FilePageBuilder (clarity:<<user>>:28263987__<<ID>>:union.viewODFFile) File "<<Filename>>" not found in path "/fs0/clarity1/clarity/files/filestore/clarity/Files/<<File path>>" 

Further testing showed that it was not possible to upload a Document to Content. It produced this message against the Filestore: 
"DMS-02107: The system is unable to create the directory in the DMS" 

As the Content Package and Documents both use Filestore, in total these symptoms indicate an issue with the Filestore. 

CA PPM On-Premise or SaaS
1) Rebuild the Index.

Use the instructions here:

DMS-02107: The system is unable to create the directory in the DMS 

CA PPM On-Premise customers can implement this directly.

CA PPM SaaS customers should contact CA Support, logging the symptoms, quoting this Knowledge Document and requesting a review.

2) Redeploy Content Package.
