Hi Rafi, It’s what I do. But I note particularly this kind of trouble when I mount my volumes manually.
In addition, when I changed my transport-type from tcp or rdma to tcp,rdma, I have had to restart my volume in order they can took effect. I wonder if these trouble are not due to RDMA protocol… because it looks like more stable with TCP one. Another idea?
