Hi All, I've just upgraded our main cluster to Luminous and have noticed that where before the cluster 64k write latency was always hovering around 2ms regardless of what scrubbing was going on, since the upgrade to Luminous, scrubbing takes the average latency up to around 5-10ms and deep scrubbing pushes it into the 30ms region. No other changes apart from the upgrade have taken place. Is anyone aware of any major changes in the way scrubbing is carried out Jewel->Luminous, which may be causing this? Thanks, Nick _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
