Go to the Centos site. You should be able to download the rpms for the kernel headers that correspond to the kernel that you are using. Then, use the rpm command to install them.
I am not sure what you are executing when you "run a postmark". If you are running a script, you may be able to call the pvfs admin apps, if there is an app that corresponds to the commands in your script. In this case, the PVFS volume does not have to be mounted. If your postmark code uses the standard gcc read and write calls, then you have to have the kernel module loaded, the client-core running, and the PVFS volume mounted. If you can modify the postmark code, you can change the read and write calls to use isys_pvfs_read and isys_pvfs_write by linking to the pvfs library; however, there are also setup steps before you can call these functions (see pvfs2-cp for example).
