I`m evaluating now version 2.8.5 and I have been able to connect and
use hosts with single port infiniband cards (Mellanox Infinihost III, )
using the ib0 Interface, connection set to
Integrating of hosts with 2-port cards fails. On this hosts I have
plugged in port ib1, configured IPoverIB and I'm able to ping between the
infiniband hosts. I have also an OpenSM Subnet Manager running on each
When starting the servers on these hosts they complain about that they
cannot reach the other pvfs2-servers and I should check if my subnetmanager
on that particular host is running.
I suppose, the connection request is sent on ib0 instead of ib1.
My question is, if there are any parameters to tell the server to use port
1 instead of port 0
Despite of all, everything runs very fine and we have very nice data
transfers (the 1-port 5 Nodes are writing with 415 MB per second).
I would appreciate any help.
