Did you create the storage space on each system: server1:pvfs2-server -f fs.conf -a server1
server2:pvfs2-server -f fs.conf -a servers What happens if you issue pvfs2-ping from either server? server1:pvfs2-ping -m /mnt/pvfs2 server2:pvfs2-ping -m /mnt/pvfs2 Becky On Mon, Oct 3, 2011 at 7:59 AM, Miltiadis Koutsokeras < [email protected]> wrote: > Hello everyone, > > I have a setup of 2 servers sharing their available free space through the > OrangeFS filesystem.
