Problems solved by technology

By detecting the status of the storage pool when an I / O exception occurs, and when the status of the storage pool is too heavy, the I / O distribution process of some services is suspended to ensure the normal operation of the business and solve the problem that the I / O cannot be delivered normally. Business interruption caused by / O and poor system stability

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0035] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0036] The delta leases of sanlock are issued by small I / O. Every time sanlock updates delta leases, a block-sized I / O is issued. In the system I / O process, generally speaking, the delivery of large I / O blocks is given priority. Therefore, when the pressu...

Abstract

The invention discloses a storage service management method and apparatus. The invention relates to a virtualized computing system technology, which solves the problems of service interruption and poor system stability caused by the fact that the I / O can not be issued normally. The method comprises the following steps of: detecting the state of a storage pool when an I / O issue to the storage poolis abnormal; Under the condition that the service pressure of the storage pool is too great, terminating the I / O distribution process of part of the service. The technical proposal provided by the invention is applicable to the service operation management of the virtualization system and realizes stable distributed resource locking.

Description

technical field [0001] The invention relates to a virtualized computing system technology, in particular to a storage service management method and device. Background technique [0002] With the rapid development of computer technology and network technology, large clusters are widely used in actual production environments. Through virtualization, a cloud computing system is formed. In a virtualized cloud computing system, it is often necessary to coordinate actions. Different systems or different hosts in the same system share the same or a group of resources. Mutual exclusion is often required to prevent mutual interference and ensure data consistency. , the effect of mutual exclusion of operations between different hosts can be achieved through distributed locks. [0003] Distributed locks generally need to support the use of large-scale environments, and sanlock can be used to manage resources in virtualization systems. Since Sanlock uses two algorithms, delta leases ...
