用bonnie测试硬盘

最近测试阵列柜,学习了三个程序,分别是:iozone，xdd，bonnie总的来说，各有优缺点。

iozone命令测试的项目比较多，结果也比较多，需要耐心察看，但是不能测试裸设备。xdd可以测试裸设备，但是可以察看的结果指标也比较少。bonnie也不能测试裸设备，相对于iozone来说项目结果比较少，相对比较清晰。

下面看一下bonnie的用法。

1,下载程序.

2,解压:[root@test root]# tar -zxvf bonnie.tar.gz MakefileInstructionsBonnie.cbonnie.1

3,编译:[root@test bonnie]# ls -al总用量 40drwxr-xr-x 2 root root 4096 5?? 11 21:46 .drwxr-x--- 15 root root 4096 5?? 11 21:46 ..-rw-rw-r-- 1 468 ftp 2451 1996-08-29 bonnie.1-rw-r--r-- 1 468 ftp 17816 1996-08-29 Bonnie.c-rw-r--r-- 1 468 ftp 551 1996-08-29 Instructions-rw-r--r-- 1 468 ftp 237 1996-08-29 Makefile[root@test bonnie]# makeOptions are "make bsd" and "make SysV" - the default is "bsd".If you get messages about missing functions, try "make SysV."make Bonnie make[1]: Entering directory `/root/bonnie'cc -O Bonnie.c -o Bonniemake[1]: Leaving directory `/root/bonnie'[root@test bonnie]# lsBonnie bonnie.1 Bonnie.c Instructions Makefile

4,命令非常简单,只有几个选项:The Bonnie command line, given here in Unix style, is:

Bonnie [-d scratch-dir] [-s size-in-Mb] [-m machine-label] [-html]

All the things enclosed in square brackets may be left out. The meaning of the things on this line is:

Bonnie The name of the program. You might want to give it a different name. If you are sitting in the same directory as the program, you might have to use something like ./Bonnie.

-d scratch-dir The name of a directory; Bonnie will write and read scratch files in this directory. Bonnie does not do any special interpretation of the directory name, simply uses it as given. Suppose you used -d /raid1/TestDisk; Bonnie would write, then read back, a file whose name was something like /raid1/TestDisk/Bonnie.34251.If you do not use this option, Bonnie will write to and read from a file in the current directory, using a name something like ./Bonnie.35152. Bonnie does clean up by removing the file after using it; however, if Bonnie dies in the middle of a run, it is quite likely that a (potentially very large) file will be left behind.

-s size-in-Mb The number of megabytes to test with. If you do not use this, Bonnie will test with a 100Mb file. In this discussion, Megabyte means 1048576 bytes. If you have a computer that does not allow 64-bit files, the maximum value you can use is 2047.It is important to use a file size that is several times the size of the available memory (RAM) - otherwise, the operating system will cache large parts of the file, and Bonnie will end up doing very little I/O. At least four times the size of the available memory is desirable.

-m machine-label This is the label that Bonnie will use to label its report. If you do not use this, Bonnie will use no label at all.

-html If you use this, Bonnie will generate a report in HTML form, as opposed to plain text. This is not all that useful unless you are prepared to write a table header.
