  • Disk lock management method, apparatus, and system
    Patent number: 11221763
    Abstract: A disk lock management method, apparatus, and system are disclosed. The method is performed by a first node, including: sending an obtaining request to a data storage system, where the obtaining request is used to request to obtain a disk lock; receiving a release request, where the release request is used to request the first node to release the disk lock; and sending, a release message to the data storage system, where the release message is used to release the disk lock. This method avoids frequent application and releasing operations performed on the disk lock, reduces disk IO resource occupancy caused by application and releasing of the disk lock, and improves overall system performance.
