ADAPTIVE STORAGE RECLAMATION |
摘要 |
In some examples, a system may include at least one class of storage that is configured for having freed storage space reclaimed to enable reuse of the freed storage space. For instance, the system may determine whether a volume corresponding to the at least one class of storage is used to store system data or user data. If the volume is used to store user data, then the system may determine whether any of the user data has been deleted from the volume. If data has been deleted from the volume, the system may determine whether an available capacity of the volume is less than a remaining capacity threshold before performing reclamation on the at least one storage device corresponding to the volume. Alternatively, if the volume is used to store system data, the system may perform reclamation based on an elapsed period of time since the last reclamation. |
