[Gluster-users] Ganesha with Gluster transport RDMA does not work

Dear All,

i have a glusterfs pool with 3 servers with Centos7.3, Glusterfs 3.8.5, network is Infiniband.

Pacemaker/Corosync and Ganesha-NFS is installed and all seems to be OK, no error logged.

I created a replica 3 volume with transport rdma (without tcp!).

When i mount this volume via glusterfs and do some IO, no errors are logged and everything seems to go pretty well.

When i mount the volume via nfs and do some IO, nfs freezes immediatly and following logs are written to

Some additional info:

Firewall is disabled, SELinux is disabled.

Different hardware with Centos 7.1 and the Mellanox OFED 3.4 packages instead of the Centos Infiniband packages lead to the same results.

Just to mention: I am not trying to do NFS over RDMA, the Ganesha FSAL is just configured to "glusterfs".

I hope someone could help me, i am running out of ideas…

Kind regards,
