Problems solved by technology

However, the triggering of the cleaning mechanism is conditional, and the cleaning will not be triggered during the data recovery process of the storage system, resulting in the OSD distribution information cached by the monitoring module becoming larger and larger, eventually causing the database usage of the monitoring module to exceed the threshold, and the monitoring module is abnormal quit

Abstract

The invention discloses a disk distribution information cutting method which comprises the following steps: starting a cutting mechanism in response to the fact that a current system meets a cutting condition; responding to the cached new disk full-amount distribution information, judging whether to trigger to cut the current disk full-amount distribution information or not according to a preset cutting triggering condition in the cutting mechanism; in response to triggering of cutting the current disk total distribution information, obtaining a cutting parameter; and cutting the current disk full-amount distribution information according to the cutting parameter. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, the database occupation of the monitoring module during a fault can be reduced, and the operation stability of the monitoring module is improved.

Description

technical field [0001] The invention relates to the field of storage, in particular to a disk distribution information clipping method, system, device and storage medium. Background technique [0002] In a distributed storage system, the stored content is cut according to a fixed size. This piece of fixed-size data is called an object. PG (Placement Group, a carrier for placing objects) is the aggregation of multiple objects. It is a logical concept. PGs are associated with objects through a consistent hash algorithm, and one PG corresponds to multiple objects. The correspondence between each PG and OSD is through the data distribution algorithm. One PG corresponds to multiple OSDs. OSD can be simply understood as a physical disk. There can be multiple PGs on one OSD, so the content you want to store placed on disk. [0003] The disk distribution information or OSD distribution information is some OSD and PG information that is necessary for the normal operation of the sto...
