Background
When a disk fails due to IO errors, the disk is disabled in storage when an event with the failing disk is being generated.
This is automatically handled for volumes with redundancy larger than 1.
For volumes with no redundancy (redundancy=1), such as temporary volumes, the volume must be locked and manual intervention (database restart) is required to recreate the volume.
Improvement
Automatic volume handling is extended to temp volumes in these scenarios.
