Storage Domain High Latency

Hi, One of my hosts is periodically reporting high latency to a storage domain (FC). There is almost no load on the SAN so the issue must be either fault, mis-configuration or internal ovirt issue. Can anyone enlighten me on how ovirt/vdsm goes about calculating the storage latency? As I'm struggling to find anything in the logs. Thanks, Alan

Can you share version information as well as the VDSM logs? Y. On Tue, Oct 11, 2016 at 7:26 PM, Alan Griffiths <apgriffiths79@gmail.com> wrote:
