on my 2-ods-node cluster, dd can only reach 13MB/s on rbd device. this is much lower than what I expected. I can get 30-60 MB/s on a ceph filesystem over the same cluster. any idea? [root@ceph-1 ~]# dd if=/dev/zero of=/dev/rbd0 bs=1M count=5000 5000+0 records in 5000+0 records out 5242880000 bytes (5.2 GB) copied, 391.508 s, 13.4 MB/s -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
