Hi Haomai,
I tried to compare the READ performance of FileStore and KeyValueStore
using the internal tool "ceph_smalliobench" and I see KeyValueStore's
performance is approx half that of FileStore. I'm using similar conf file
as yours. Is this the expected behavior or am I missing something?
Than
in all, maybe you could tell more about "ceph_smalliobench"

Hi,
I followed the instructions at http://ceph.com/docs/next/rbd/rbd-openstack/
I was able to configure for glance, cinder and nova. However, when I try to
do the backup, I get an error "ERROR: Service cinder-backup could not be
found. (HTTP 500)
I installed cinder-block, added the following in c
Hi,
I understand that Ceph is a scalable distributed storage architecture.
However, I'd like to understand if performance on single node cluster is
better or worse than a 3 node cluster.
Let's say I have the following 2 setups:
1. Single node cluster with one OSD.
2. Three node cluster with one OS
