Hello,

Is there a way to keep Mellanox OFED and oVirt/RHV playing nice with each other?

The real issue is regarding GlusterFS. It seems to be a Mellanox issue, but I would like to know if there's something that we can do make both play nice on the same machine:

Is this ok [y/N]:

I really don't care for GlusterFS on this cluster, but Mellanox OFED is much more relevant do me.

Thank you all,
Vinícius.
