WARNING: Possible file removal when executing a Recreate Thumbnails and Previews maintenance job in ADAM 5.2 and ADAM 5.3
This message is directed to all customers using ADAM 5.2 (all versions) or ADAM 5.3 (all versions) in combination with File Stores and requires immediate action.
A critical issue has been identified in all versions of ADAM 5.2 and all versions of ADAM 5.3, where the indexed file is lost when executing a RefreshFiles maintenance job (Recreate Thumbnails and Previews) on a file that is being stored on an ADAM File Store.
This issue appears in the following ways:
- By manually or programmatically triggering a RefreshFiles maintenance job on a record containing files that are stored in a File Store
- By ingesting files for which previews are created in a delayed fashion when these files are stored on File Stores. This happens for example while ingesting video’s.
An administrator can identify this issue because the RefreshFiles maintenance job will fail with a “System.IO.FileNotFoundException: Could not find file” exception.
All customers impacted by this situation are required to take immediate action to prevent any data loss. This issue has been identified internally and no customers have reported any issues so far.
Until the fix is available and has been installed, please
- Do not ingest files with delayed preview creation
- Do not use the RefreshFiles maintenance job
We are currently working on fixes for ADAM 5.2 and ADAM 5.3. As soon they are available we will make them available in our Download Center and update this knowledge base article. We strongly recommend all of our customers to install this fix as soon as it is available.
