Embodiment

[0045] Ceph cluster OSD accelerated disk expansion method of the present invention comprises the following steps:

[0046] S1. Select the acceleration disk expansion method according to the management method of the Ceph cluster OSD:

[0047] ①. When the OSD acceleration device adopts the disk partition method, use the method of creating a new partition and migrating old data, and expanding the BlueFS file system to expand the space size of the acceleration disk;

[0048] ②. When the OSD acceleration device adopts the logical volume mode, expand the volume group, expand the logical volume, and expand the BlueFS file system;

[0049] S2. Restart the extended OSD service, and detect the status of the Ceph cluster.

[0050] as attached figure 1 As shown, the BlueStore technology principle used by Ceph, in order to improve the writing performance of Ceph, the Ceph community developed BlueStore, a storage backend, which allows data to bypass the local file system and directly oper...

Abstract

The invention discloses a capacity expansion method of a Ceph cluster OSD acceleration disk, and belongs to the field of cloud computing, the technical problem to be solved by the invention is how toredeploy a Ceph cluster without redeploying the Ceph cluster. The space size of the block. Db or the block. Wal of the deployed OSD is expanded; according to the technical scheme, the method comprisesthe steps that according to the management mode of a Ceph cluster OSD, a disk partition mode or a logical volume mode is selected for accelerating disk expansion, OSD service is restarted after the accelerating disk expansion, the state of the Ceph cluster is detected, and it is ensured that the OSD service adopts a new acceleration space; wherein when the OSD acceleration equipment adopts a diskpartition mode, the space size of an acceleration disk is expanded by newly establishing a partition, migrating old data and expanding a BlueFS file system mode; when OSD acceleration equipment adopts a logical volume mode, the space size of an acceleration disk is expanded by expanding a volume group, expanding a logical volume and expanding a BlueFS file system mode.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method for expanding the capacity of a Ceph cluster OSD acceleration disk. Background technique [0002] Ceph is a distributed storage system, which has the characteristics of reliability, intelligence, and distribution, and realizes functions such as high reliability, high scalability, high performance, and high automation, and finally stores user data. [0003] BlueStore is a storage system built on the underlying raw device, with a built-in RocksDB key / value database for managing internal metadata. A small internal interface component called BlueFS implements a filesystem-like interface to provide enough functionality for RocksDB to store its files and share the same raw device as BlueStore. BlueStore can manage three main types of devices: the main device is the OSD disk device, the db device stores the object metadata (RocksDB), and the wal device stores the pre-written log...
