Pinned topic iozone problem

‏2012-04-16T12:52:27Z |
Hi,

anybody using iozone on AIX here?

Today I first time downloaded and started to learn iozone (I found AIX rpm package in version 3.398), but all tests I run ended like this:


Error writing block 1181, fd= 3   iozone: interrupted   exiting iozone


blok number varies (I saw 1180 - 1183).

This is AIX 5.3 and Im testing SVC disks.

I somehow failed to find any solution to this on google, so any help is welcomed

Regards

    Well, it seems to be related to -b switch, '-b 1G' works, '-b 2G' fails, ulimit -a says that file size is unlimited.

    But for now testing with file size 1G is sufficient for me..

    Hello,

    I'm running into this same issue. My server has 2GB of RAM, so I need to test file over 2GB.

    Getting same error. Using JFS2 ulimit -f unlmited is set.

    I can do "dd" and create a file larger that 2GB. I'm narrowing it down to a iozone problem...

    ::SOLVED::

    You must enable large file support during the iozone complie:

    $make AIX-LF
