OCFS2/InlineDataTest

OCFS2 Inline Data Test

Introduction

This document aims at scheduling the testing plan against Xattr which we're currently implementing on Ocfs2,and also capture/record the testing result to trace the status during test where we can easily position a bug.In an addition,we also explain how all of the testcases will be organized and the workflow of their corresponding testing tool.

TestLimitation

The limitation defined by desgin roadmap during inline data implementation on ocfs2 should be claimed here to make a clear understanding of how can we expect our testing tool most.

MAX_INLINE_DATA_SIZE            ocfs2_max_inline_data()
MAX_FILE_NUMS                       defined by ulimit
OCFS2_MAX_FILENAME_LEN        255
OCFS2_MAX_SLOTS                    255
OCFS2_MAX_BLOCKSIZE              4k
OCFS2_MAX_CLUSTERSIZE          1M

Testcases

we concentrated on feature,stress and boundary test for kernel fs and tools both in single and multiple nodes,and then formalize these into a testing tool package.currently,we'll only focused on inline data testing without EA enabled to avoid a confusion here.during test,2 kinds of inodes are expected to be mentioned:regular file and directory.

1.Single-node Case,all cases scheduled in single_inline_run.sh,basically all generic cases provided by single_inline_test.c while some other cases for tools built by shell

1.FS Feature test,consists of a set of file operations around the cut-off limitation for inline data,it includes buffered read/write,mmap read/write, and truncate to a sparse file with various file flags and mode,moreover,a sanity check should be conducted under a series of block and cluster size(-b 512/1k/2k/4k,-C 4k/8k/16k/../1M)

2.Tools Feature test,consists of a set of file operations by calling APIs provided by libocfs2,and also include a shell test of provided tools,i.e,mkfs,debugfs,tunefs.etc.

3.Boundary test,doing testing with growing a file into a exact size which will extent the inline data to external blocks,this include both fs and tools fields.

4.Concurrent operations test with multiple forked processes against one file,this mainly focus on fs test.

5.Multiple file test,manipulates thousands of file simultaneously via spreading the same amount of processes to perform file operations,this include both fs and tools field.

6.Stress test,punch the test by tuning workload extremely high,including file_nums,process numbers.this include both fs and tools field

 

2.Multi-nodes Case

NOTE:To launch the multi-nodes test,need to install openmpi first,and a configuration of ssh or rsh passwordless access also needed in advance.

Still plan to do test with the help of openmpi,have not schedule the plan yet.should be built on the basis of single test.

Testing Tools

Currently,since I've not got a svn/git repo for source code,I just kept my latest tools src locally on testing nodes,will move to a proper repo soon once get one.

Name

Script / Program

Description

Technology

Useful?

What is tested

inline_data_test

single_inline_test.c
single_inline_run.sh

These script and c program together help to coordinate inline data test on single node,including feature,boundary and stress test.

Shell,C

1

Yes

Check basic inline data functionality on ocfs2 on single node,and stress the the test by tuning workload,also emulate a race to perform concurrent operations on files between multi-nodes.

multinode_inline_test.c
multinode_inline_run.sh

propagate processes on multiple nodes to take a race for files operations on one file to test if inline data support behave well on concurrent events

C,Shell,Openmpi

2

Yes
