Hi all,<br>
<br>
I'm performing benchmarking on OCFS2 file system on LVM using fio
tool. <br>
There are some scenarios that when we run it, after few minutes,
computer will reboot automatically. These scenarios are related to
OCFS2 file system only (there is no problem with ext3).<br>
<br>
We tried to fix by adding option "--debug" in fio command <br>
(example: <i>fio RandWR-ASync-IOdepth1-FixFileSize
--output=RandWR-ASync-IOdepth1-FixFileSize.out </i><i><b>-</b></i><i><b>-debug=io</b></i>).
Some scenarios can run successfully without rebooting. But there are
still some scenarios cannot run successfully.<br>
<br>
We tried to upgrade Linux kernel from 3.4.34 to 3.10.65 (after
referred to link:

Some scenarios can run successfully without rebooting. But there are
still some scenarios cannot run successfully.<br>
