[Gluster-users] Starting RDMA volume fails

Tue Nov 10 16:49:32 UTC 2015

Hi,

seems like RHEL/CentOS package glusterfs-rdma (from the gluster repo) is 
not working together with the Mellanox ofed.
Guess the problem is in the dependency of libibverbs which depends on 
the rdma package of RHEL/CentOS.
Installation of glusterfs-rdma might break your Mellanox ofed 
installation. At least on the four systems (with three different 
kernels) I tried, the openibd.service was unusable because of the 
rdma_cm module installed by the rdma package.
Is there something I can do in case I would like to use glusterfs but 
need the Mellanox ofed or do I have to discard the idea of using 
glusterfs for my setup?

Best regards,
Jochen
