Abstract
Exemplary methods, apparatuses, and systems determine that a disk drive in a distributed storage system is failing. In response to determining that the disk drive is failing, it is determined if an object has object components stored on the failing disk drive. Object components are flagged based on whether the object components will become inaccessible in the event the disk drive fails or is unmounted. Object components that are flagged with an evacuate flag are migrated from the failing disk drive to one or more other disk drives in the distributed storage system to prevent objects from becoming inaccessible.
