Ok, on a std Rocks Cluster install (CentOS 4.4) the instructions given by Murali (below) ran without any errors or warnings (that I could see). I think the only change is: --prefix=/opt/pvfs2.
While I'm feeling more comfortable with the idea of upgrading to v2.6.2 I have some questions/confirmations before I dive in tomorrow (it's getting late here): 1) Can I just `cp` the relevant /opt/pvfs directories from the frontend to the nodes, or is it better to build/make install on the nodes? 2) Can I use the server and client configuration files from the v1.5.1 installation? I'm assuming those configuration files are 'good', and v2.6.2 has not altered them.... In this scenario I'm thinking of just replacing the compiled/binary files and leaving all else unchanged 3) If I do have to run pvfs2-genconfig, etc will my current data in /mnt/pvfs2 be erased? Thanks in advance Regards Mark PS Reminder: In case I forget or someone else comes along this path.... Reinstalling the Rock Cluster, or executing 'shoot-node' will undo all this and you'll be back to v1.5.1. There is also the separate issue of formatting and the status of /state/partition1...

Hi Mark, No problem. In fact I am a newbie to the Rocks Roll setup, so someone needs to correct me if the installation steps outlined below do not work on your setup. Hmm.. Unfortunately, it is a build time option and not a run time option. Download the pvfs2 source tarball. Any release tarball should do fine. ftp://ftp.parl.clemson.edu/pub/pvfs2/pvfs-2.6.2.tar.gz Then type ./configure --with-kernel=</path/to/kernel26/> --enable-kernel-sendfile --prefix=/usr/local/pvfs2/ then type make && make kmod && make install Assuming you have the kernel sources/headers correctly installed and a working gcc compiler, this build should work ok. After that, you can follow the same steps outlined in the pvfs2 quick start guide to setup your system (servers, kernel module, client-core and finally mount!) Sigh.. I really wish there was an easy way out. Sorry about that. If someone knows how to roll out a Rocks-Roll images, I am sure they will chime in.. I have no clue how to do it. thanks Murali On 2/20/07, Mark Van De Vyver <[EMAIL PROTECTED]> wrote: > Hi Murali, > Thank you for responding.
