Abstract: A method for improving the performance of a RAID under rebuild is disclosed. In one embodiment, such a method includes identifying a RAID requiring rebuild, such as by identifying a RAID having one or more failed storage-drive components. The method then automatically performs the following in response to identifying the RAID: the method identifies hot extents (i.e., extents most heavily accessed) in the RAID; the method migrates the hot extents from the identified failed RAID to a normal RAID not requiring rebuild, such as to an underused RAID; and the method rebuilds the failed RAID. The migration of the hot extents will ideally occur while the RAID is being rebuilt but may also be performed prior to the rebuild process. A corresponding apparatus and computer program product are also disclosed.

Abstract: A tubular lever lock has a lock body and a bolt connected to each other, an interior handle assembly, an exterior handle assembly, an interior button assembly connected to the interior handle assembly and the lock body, and an exterior clutch assembly connected to the exterior handle assembly and the lock body. Position of an adjusting tube relative to a driving rod of the interior button assembly is adjustable to allow the tubular lever lock to match a thickness of a door. A pressing panel and a transmission tube of the exterior clutch assembly are able to disengage from each other so the exterior handle assembly is unable to drive the lock body.
