<div dir="auto">Dear Deepak, thank you for the hints, which gluster are you using?<div dir="auto">As you can see from my previous email that the RDMA connection tested with qperf. It is working as expected. In my case the clients are servers as well, they are hosts for the ovirt. Disabling selinux is nor recommended by ovirt, but i will give a try.</div></div><div class="gmail_extra"><br><div class="gmail_quote">Am 03.03.2017 7:50 vorm. schrieb "Deepak Naidu" <<a href="mailto:dnaidu@nvidia.com">dnaidu@nvidia.com</a>>:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
