How to use Bonnie++ in Linux ?

In my previous article I have shown how we can install bonnie++ in Linux. After that I started playing with it. In this article showing the usage of Bonnie++.

Step 1 : As we can’t the run the bonnie using root user. I have created user user1 to run the bonnie.

[root@Node2 ~]# bonnie++ -d /tmp -s 2G -m FIRST -f -b -u user1
Using uid:500, gid:500.

Step 2 : During the test I went to /tmp directory to see what exactly Bonnie is doing.

cd /tmp
ls -lrt Bonnie*
drwx——. 2 user1 user1 532480 Sep 22 17:09 Bonnie.5583

cd Bonnie.5583
[root@Node2 Bonnie.5583]# ls -lrt | wc -l
8887

It has created so many empty files in it. Just randomly checking one file in it.

[root@Node2 Bonnie.5583]# cat iQSm5MiG0007844
[root@Node2 Bonnie.5583]# file !$
file iQSm5MiG0007844
iQSm5MiG0007844: empty
[root@Node2 Bonnie.5583]# stat !$
stat iQSm5MiG0007844
File: `iQSm5MiG0007844′
Size: 0               Blocks: 0          IO Block: 4096   regular empty file
Device: fd00h/64768d    Inode: 433408      Links: 1
Access: (0600/-rw——-)  Uid: (  500/   user1)   Gid: (  500/   user1)
Access: 2014-09-22 17:09:37.154097650 +0530
Modify: 2014-09-22 17:09:22.710004214 +0530
Change: 2014-09-22 17:09:22.710004214 +0530

Step 3 : After that if you want to see the output of step 1 in more organized form. We can take the last line from output. Use the below command to convert it into html format.

[root@Node2 ~]# echo “FIRST,2G,,,35295,12,23174,7,,,73718,10,95.6,1,16,321,8,+++++,+++,366,3,259,6,+++++,+++,372,3” | bon_csv2html > /tmp/first.html

Step 4 : I copied the first.html file to my windows machine using winscp. Now we can see the results by opening it with browser.
