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.

Abstract: The present invention relates to a computer system and a clock configuring method. The computer system comprises at least two nodes, wherein each of the at least two nodes includes a selecting module and a CPU, inputs to the selecting module of any node comprise a clock of the node and a clock output from other node, and an output terminal of the selecting module is connected to the CPU and an input terminal of the selecting module of other node; the computer system further comprises a clock controlling module, whose output terminal is connected to a control terminal of the selecting module to control the clocks of the at least two nodes to be the same clock. When clocks of plural nodes are abnormal, the computer system can still normally operate as long as there is a normal clock in the computer system.
