Abstract: The present application relates to a storage device operation control method, a storage device, and a management node. The method includes: receiving at least one request sent by at least one management node; and when one of the at least one request is a permission application request, determining, according to a current permission status, whether to assign operation permission to a management node that sends the permission application request; or when one of the at least one request is an operation request, determining, according to a current permission status, whether a management node that sends the operation request has operation permission, and performing an operation according to the operation request when the management node that sends the operation request has the operation permission. This avoids a conflict caused by simultaneously performing an operation on a storage device by multiple management nodes, and prevents successive serial operations from being interrupted.
