[Linux-cluster] gfs2 kernel versions



Hi there,

 

right now we have a centos 6.4 (2.6.32-279) and a Gentoo (3.1.6) gfs2 cluster running.

The centos cluster shows some weird behavior with PHP processes “dying” with process state D (uninterruptable IO). The Gentoo cluster never had any of those problems.

 

So I wanted to figure out what gfs2 versions both are running, but I cant find any significant information on that (changelogs based on kernel versions etc.)

Is there any improvement in gfs2 going on in kernels like 2.6.32? or would it be much better to upgrade to a recent version (3.12 e.g.) to get all the performance features and bugfixes?

Or is gfs2 split up in separate packages (gfs2-util etc.) and you can run current versions of gfs2 also on 2.6.32 kernels?

 

Thanks in advance for your help. This really confuses me.

 

Juergen
