Shared File System Failover
If the network connection between the application server and the shared file system fails when a workflow is in process, processing will wait and retry the current activity.
If the network connection fails while writing data to the file system, the application attempts to reconnect a specified number of times. If the network connection is re-established, workflows will resume processing. If the file system is still not available after the specified retries, messages are retained in the queue and the application is shutdown. When the filesystem is up and connected to network and the application is up, this message is redelivered for execution.
If the network connection fails while submitting a work item through the UI, the user interface will be down, but when connectivity is restored, the work item will be in the same state prior to failure. If a submitted work item need to be merged with the previous copy, and if the file system fails during merge, it will be repeated based on the configured timeout and retries.
