SYSTEMS AND METHODS FOR FAIL-SAFE OPERATIONS OF STORAGE DEVICES

摘要

Techniques for enabling fail-safe operations of storage devices are described. A device may be configured to delete an inode in a failsafe manner. A device may be configured to mark directory entries as not in use and ensure this goes to disk before anything else. A device may be configured to create an inode in a failsafe manner. A device may be configured to allocate and initialize a cluster and ensure this is written to disk before anything else. In this manner, a volume may be in a predictable state upon a failure occurring.
