Hi Ariel I see over on the irc channel that you do not want to use MPI. I just wanted to point out that you could use the MPI_FILE routines even if your application is serial. > Another issue is, although i copied > /usr/src/pvfs-2.8.1/examples/pvfs2-server.rc > to /etc/rc.d/init.d/pvfs2-server i can't do /etc/rc.d/init.d/pvfs2-server > start or > /etc/rc.d/init.d/pvfs2-server stop. Why is this? I think pvfs2-server.rc might only work out-of-the-box on redhat-like systems? I'm not sure: it probably requires some site-specific modifications. You might be better off starting and stopping by hand if you aren't familiar with your distributions init scripts. > In the machine that i want to mount the pvfs2 volume i did > > cd /usr/src/pvfs-2.8.1/src/apps/kernel/linux/ > ./pvfs2-client -f -p ./pvfs2-client-core > > and the result was > > pvfs2-client starting > Spawning new child process > Waiting on child with pid 5544 > About to exec: ./pvfs2-client-core, with args: pvfs2-client-core --child -a > 5 -n 5 --logtype file -L /tmp/pvfs2-client.log > > but nothing more happened. Whatn is wrong? Looks like it's behaving exactly as it should: you passed the -f flag, which keeps it in the foreground. You should be able to, in another terminal, mount PVFS now. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
