> Hello Guys,
>
> We wrote a tool with Python, which is used to display DLM lock usages in a
OCFS2
> cluster.
> o2locktop is a top-like OCFS2 DLM lock monitor, it displays DLM lock usages
via
> querying OCFS2 file system statistics from the specified nodes.
> Therefore, OCFS2 kernel modules must enable OCFS2_FS_STATS configuration
> option when compiling.
> If you want to know if the current OCFS2 kernel modules enable
OCFS2_FS_STATS
> setting, you can refer to /boot/config-`uname -r` file.
> You can utilize o2locktop to detect the hot files/directories, whose DLM
locks are
> frequently referenced among the cluster.
> You can get the maximal wait time per DLM lock, this helps you identify
which hot
> files/directories should be decoupled for improving file access
performance.
