First let me say, I hope this is the right list for this email, if not
please forgive me.
I have a small 16 node compute cluster. The university where I work
at recently opened a new Datacenter. My cluster was moved from the old
Datacenter. Before the move the inifiniband was working properly,
after the move the ipoib has stopped working.
The cluster runs Centos 4 with all the latest updates and the Centos
distributed OFED code. My plan was to update the OFED code once things
had restablized.
For the move, I shutdown the cluster, removed the inifiniband cables and
the cluster was moved. I then reinstalled the infiniband cables (not
in the same order before the move) and brought every thing back up.
When i brought the cluster back up the ipoib would not work. The only
message in the log file is "Mar 15 04:04:32 h2o01 kernel: ib0: multicast
join failed for ff12:401b:ffff:0000:0000:0000:ffff:ffff, status -22".
The master node can see all the systems:

I've reset the sm on the switch, but nothing seems to work.
Any ideas of where to look for whats causing the problem?
