CPU: 2 x E5-2603 @1.8GHz RAM: 16GB Network: 1G port shared for Ceph public and cluster traffics Journaling device: 1 x 120GB SSD (SATA3, consumer grade) OSD device: 2 x 2TB 7200rpm spindle (SATA3, consumer grade)
0.84 MB/s sequential write is impossibly bad, it's not normal with any kind of devices and even with 1G network, you probably have some kind of problem in your setup - maybe the network RTT is very high or maybe osd or mon nodes are shared with other running tasks and overloaded or maybe your disks are already dead... :))
As I moved on to test block devices, I got a following error message: # rbd map image01 --pool testbench --name client.admin
You don't need to map it to run benchmarks, use `fio --ioengine=rbd` (however you'll still need /etc/ceph/ceph.client.admin.keyring)
