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
