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

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 _______________________________________________ Users mailing list [email protected] <mailto:[email protected]> http://lists.ovirt.org/mailman/listinfo/users <http://lists.ovirt.org/mailman/listinfo/users>
