description The invention discloses a ceph mirror image block device unloading method, a ceph mirror image block device unloading system and a storage medium. The method comprises the steps of additionally arranging forced switch parameter options in an unloading instruction of a ceph mirror image block device; judging whether the obtained unloading instruction has a forced switching parameter or not, and ifso, performing forced zero clearing processing on the reference count of the ceph block equipment; otherwise, executing the next step; judging whether the reference count of the ceph block equipment is greater than 1 or not, if so, refusing to execute the unloading operation, and feeding back error information; otherwise, carrying out unloading processing on the ceph mirror image block equipment.According to the method, forced unloading operation can be performed on the ceph mirror image according to actual application scene requirements. All application programs occupied by the ceph mirror image do not need to be sto
