Problems solved by technology

If the data block is set too small, it will cause a large number of input / output operations when processing large-capacity write requests, which will greatly reduce system performance; on the contrary, it will cause waste of disk space and reduce system performance when processing small-capacity write requests. processing speed

Embodiment Construction

[0060] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0061] image 3 and Figure 4 Shown is the method for automatically adjusting the disk space size of the write synchronous replication of the snapshot device according to the present invention. Wherein, the letter A represents the processing flow when the serial number of the data block in the write request is greater than the value of the initial serial number of the first disk space plus the value of the maximum number.

[0062] Such as figure 2 In the snapshot processing flow of the write request processing shown in the known technology, when there is no information corresponding to the data block of the write request in the hash table, and the write synchronous copy operation needs to be performed in step 208, the present invention can be used to Alternative to known processing methods.

[0063] First, in step 300, a first disk ...

Abstract

The invention relates to a method used for automatically adjusting the size of disk space of write-in and replication of a snapshot device. A first disk space of the snapshot device is initialized anda data block of the first disk space is carried out the operation of write-in and replication; whether the serial number of the data block requested by written-in is arranged in the first disk spaceis judged; when serial number of the data block requested by written-in is arranged in the first disk space, the first disk space is maintained; when the serial number of the data block requested by written-in is not arranged in the first disk space, a second disk space is initialized, and the number of the data block of the second disk space and the number of the maximum-continuous data block inthe first disk space is equal and the data block of the second disk space is carried out the operation of write-in and replication; the invention can automatically adjust the size of disk space of write-in and replication and more continuous operations of write-in and replication can be concentrated and finished for once; the performance of the system can be improved by the continuous, concentrative and burst requirement.

Description

technical field [0001] The invention relates to a storage system management method, in particular to a storage system snapshot device management method. Background technique [0002] Logical Volume Management (LVM) based on Linux systems is implemented by adding an additional layer in the input / output (I / O) subsystem. This layer between the file system and the physical disk drive is called Logical Volume Management. Volume device driver layer (Logical Volume Device Driver, LVDD. Through the logical volume device driver layer, the upper file system or other applications obtain a virtual view of the disk or partition. Please refer to figure 1 , the logical volume management opens a physical volume (Physical Volume, PV) 120 composed of multiple physical blocks (Physical Extent, PE) 140 on multiple storage devices of the same type (such as hard disks, RAID devices), and stores these physical volumes The volumes 120 are combined into a volume group (Volume Group, VG) 100 through...
