Abstract

A method for upgrading client software includes receiving an upgrade instruction for client software deployed on a computing node, where the client software is used to access one or more storage nodes in the storage system based on a received input/output I/O instruction; performing I/O suspension on the received I/O instruction in response to the upgrade instruction; and upgrading the client software based on the upgrade instruction.

First claim

What is claimed is:

1 . A method comprising:
receiving, by a client software, a first input/output (I/O) instruction to access one or more storage nodes of a storage system; receiving an upgrade instruction for the client software; performing I/O suspension on the first I/O instruction in response to the upgrade instruction; and upgrading the client software based on the upgrade instruction.

2 . The method according to of claim 1 , further comprising:
generating buffered data in response to the first I/O instruction; sending the buffered data to the one or more storage nodes; and performing, in response to the upgrade instruction, the I/O suspension after sending the buffered data to the one or more storage nodes.

3 . The method according to of claim 2 , further comprising:
receiving a second I/O instruction while sending the buffered data to the one or more storage nodes; processing the second I/O instruction in a manner of synchronously accessing the one or more storage nodes.

4 . The method according to of claim 1 , further comprising:
determining that the client software has completed being upgraded to obtain an upgraded client software; canceling the I/O suspension; and processing, based on the upgraded client software, the first I/O instruction.

5 . The method of claim 1 , wherein upgrading the client software comprises upgrading a core module of the client software.

6 . A computing node, comprising:
one or more memories are configured to store instructions; and one or more processors configured to execute the instructions to cause the computing node to:
receive, by a client software, a first input/output (I/O) instruction to access one or more storage nodes of a storage system;
receive an upgrade instruction for client software;
perform I/O suspension on the first I/O instruction in response to the upgrade instruction; and
upgrade the client software based on the upgrade instruction.

7 . The computing node of claim 6 , wherein the one or more processors are further configured to execute the instructions to cause the computing node to:
generate buffered data in response to the first I/O instruction; send the buffered data to the one or more storage nodes; and perform, in response to the upgrade instruction, the I/O suspension after sending the buffered data to the one or more storage nodes.

8 . The computing node of claim 7 , wherein the one or more processors are further configured to execute the instructions to cause the computing node to:
receive a second I/O instruction while sending the buffered data to the one or more storage nodes; process the second I/O instruction in a manner of synchronously accessing the one or more storage nodes.

9 . The computing node of claim 6 , wherein the one or more processors are further configured to execute the instructions to cause the computing node to:
determine that the client software has completed being upgraded to obtain an upgraded client software; cancel the I/O suspension; and process, based on the upgraded client software, the first I/O instruction.

10 . The computing node of claim 6 , wherein the one or more processors are configured to execute the instructions to further cause the computing node to: upgrade a core module of the client software based on the upgrade instruction.

11 . A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable storage medium, wherein the computer-executable instructions when executed by a processor of an apparatus, cause the apparatus to:
deploy a client software on a computing node, wherein the client software is configured to access one or more storage nodes of a storage system; receive, by the client software, a first input/output (I/O) instruction to access the one or more storage nodes; receive an upgrade instruction for client software; perform I/O suspension on the first I/O instruction in response to the upgrade instruction; and upgrade the client software based on the upgrade instruction.

12 . The computer program product of claim 11 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the apparatus to:
generate buffered data in response to the first I/O instruction; send the buffered data to the one or more storage nodes; and perform, in response to the upgrade instruction, the I/O suspension after sending the buffered data to the one or more storage nodes.

13 . The computer program product of claim 12 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the apparatus to:
receive a second I/O instruction while sending the buffered data to the one or more storage nodes; process the second I/O instruction in a manner of synchronously accessing the one or more storage nodes.

14 . The computer program product of claim 11 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the apparatus to:
determine that the client software has completed being upgraded to obtain an upgraded client software; cancel the I/O suspension; and process, based on the upgraded client software, the first I/O instruction.

15 . The computer program product of claim 12 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the apparatus to upgrade a core module of the client software based on the upgrade instruction.

16 . The computer program product of claim 15 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the apparatus to:
receive the first I/O instruction at an interface module of the client software; and transmit the first I/O instruction to the core module.

17 . The computer program product of claim 16 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the core module to synchronously access storage data in the one or more storage nodes.

18 . The computer program product of claim 17 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause a control module of the client software to send the buffered data to the one or more storage nodes.

19 . The computer program product of claim 18 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the control module to send, in response to the upgrade instruction, a control command to the interface module to perform I/O suspension on the first I/O instruction.

20 . The computer program product of claim 19 , wherein the computer-executable instructions when executed by the processor of the apparatus, further cause the interface module to execute the control command to perform I/O suspension on the first I/O instruction.
