Hi, Is it possible to do random write bench with rados bench command ? I have very base random write performance with 4K block size inside qemu-kvm, 1000 iops/s max with 3 nodes with 3x 5 disk 15k (Maybe it's related to my constant disk writes, like datas are not flushed sequentially to disk)
seekwatcher movie of 1 osd here : http://odisoweb1.odiso.net/random-write-4k.mpg I would like to do tests on kvm host with rados command to compare. (I don't have rbd module in my kvm host kernel,so I can't use fio on the host) Regards, Alexandre -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
