Hi - Like Becky and I mentioned, you'll also need to start the pvfs2-client daemon to be able to access the pvfs2-fs via the kernel module, only then will you able to mount it.
So far all you've done is start up a metadata and io server, in the typical client/server context this only amounts to starting the server. In order to access it via a 'client'-mode you need to load the pvfs2.ko kernel module and the pvfs2-client http://www.pvfs.org/cvs/pvfs-2-8-branch-docs/doc//pvfs2-quickstart.pdf check out ch5.4.1 Kyle Schochenmaier On Mon, Jan 9, 2012 at 2:59 PM, g_p g_p <[email protected]> wrote: > Hello, > > the client10 is both a client and a datanode.
