[Pvfs2-users] pvfs2 + open-mx on single node

[Phil Carns]

Just a quick update in case anyone finds this thread in the list 
archives later.  We were able to resolve the problem offline (with help 
from Brice Goglin).   The BMI address in the fs.conf file just needed to 
be changed from "mx://oroppas:0:0" to "mx://localhost:0" to match 
address reported by omx_info.

Alternatively, omx_hostname could have been used to manually set a 
different address for the node.
