Hello, I run a test cluster of 3 machines with 24 HDDs each, running bare-metal on CentOS 8. Long story short, I can have a bandwidth of ~ 1'200 MB/s when I do a rados bench, writing objects of 128k, when the cluster is installed with Nautilus. When I upgrade the cluster to Pacific, (using ceph-ansible to deploy and/or upgrade), my performances drop to ~400 MB/s of bandwidth doing the same rados bench. I am kind of clueless on what makes the performance drop so much. Does someone have some ideas where I can dig to find the root of this difference? Thanks, Luis Domingues _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
