Embodiment 1

[0027] see figure 1 , figure 1 It is a schematic flowchart of the online upgrade method for Internet protocol storage in Embodiment 1 of the present application. The specific steps are:

[0028] Step 101, the storage node starts the first storage service program, and uses the first storage service program to process when receiving the access request sent by the storage client.

[0029] Step 102, when the first storage service program needs to be upgraded, the storage node starts the second storage service program, and closes the first storage service program; when receiving the access request sent by the storage client, uses the second storage service program deal with.

[0030] Step 103, the storage node upgrades the first storage service program, and after the upgrade is completed, starts the upgraded first storage service program, and uses the upgraded first storage service program when receiving an access request sent by the storage client. Service program processing. ...

Embodiment 2

[0033] see figure 2 , figure 2 It is a schematic flowchart of the online upgrade method for Internet protocol storage in Embodiment 2 of the present application. The specific steps are:

[0034] Step 201, the storage node starts the first storage service program, and uses the first storage service program to process when receiving the access request sent by the storage client.

[0035] Since the service address provided by the storage node to the storage client is the service address configured for the first storage service program, under normal circumstances, for example, when the storage service program does not need to be upgraded, the first storage service program is used to process storage The access request sent by the client.

[0036] see image 3 , image 3 It is a schematic diagram of the storage access process before the online upgrade in the embodiment of this application. image 3 The middle storage node configures the service address 192.168.1.1 for the fi...

Abstract

The invention provides an Internet protocol storage on-line upgrading method. The Internet protocol storage on-line upgrading method comprises the steps that a storage node starts a first storage service program, and when an access request sent by a storage client side is received, the access request is processed through the first storage service program; when the first storage service program needs to be upgraded, a second storage service program is started, the first storage service program is stopped, and when the access request sent by the storage client side is received, the access request is processed through the second storage service program; the first storage service program is upgraded through the storage node, after upgrade operation is accomplished, the upgraded first storage service program is started, and used for processing the access request when the access request sent by the storage client side is received. On the basis of the same inventive concept, the invention further provides an Internet protocol storage on-line upgrading device. When on-line upgrade operation is conducted, reliability of system operation can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Internet protocol storage online upgrade method and device. Background technique [0002] In the existing distributed or centralized IP storage, when the storage service program on the storage node needs to be upgraded, the storage node needs to go offline first, and then go online after the upgrade is completed to realize the upgrade of the storage program. [0003] Take the stored program upgrade process in the distributed storage mode as an example: multiple storage nodes form a storage cluster, and the stored program is upgraded node by node. When the stored program on one of the storage nodes is upgraded, the storage node exits the storage In the cluster, the read and write access to the storage node becomes the access to the copy data of the storage node, and the copy data can run on the storage node in the current storage cluster. After the storage node that exi...
