Hi, We've got a 8-host cluster running oVirt 4.1; each host is connected via iscsi to a EQL 4100 storage (2x). Most of the VMs use barely any IOPS, however on our storage controller we've noticed a constant steam of reads, about 2000 IOPS; any idea what might cause the ovirt hosts to hammer on the storage so much? Looking at iotop, it seems that systemd-udevd is being activated every few seconds (and its IO% is usually fairly high) so I assume this might be somehow related. Thanks, Andrea
