There was a mistake in my last email.
My last nfs mount test with no rdma was not correct, I've retried with
[r...@my_host ] #mount -o rw 192.168.0.215:/vol0 /mnt/
My nfs partition is mounted and everything is correct, which confirms that
the problem comes from rdma connection manager.

Hi,
I've updated nfs-utils package:
[r...@my_host ~]# mount.nfs -V
mount.nfs (linux nfs-utils 1.1.6)
[r...@my_host ~]# strace mount.nfs
192.168.0.215:/vol0 /mnt/ -o rdma,port=2050
Does it work without rdma?
The problem is exactly the same without rdma:
[r...@my_host ~]# strace mount.nfs 192.168.0.215:/vol0 /mnt/ -o
rw,port=2050

Celine, can you establish regular rdma
connections over your IB link? Like rping?
I can't etablish rdma connection, following errors occur with rping :
[r...@my_host ~]# rping -c 192.168.0.214
cq completion failed status 5
wait for CONNECTED state 10
connect error -1
cma event RDMA_CM_EVENT_REJECTED, error 8
My kernel is a 2.6.27 kernel.org build on a Red Hat Distribution : Red
Hat Enterprise Linux Server release 5.3 Beta (Tikanga).
Céline.
