Hi Simone,
we are exposing 2x 5TB LUNs, used solely by the ovirt cluster.

Thanks
Andrea

    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.


mmmh this could be an hint: how many LUNs are you exposing on the iSCSI portal used for the hosted-engine LUN?


    Thanks,
    Andrea
