Ah, this appears to be http://tracker.ceph.com/issues/6087.
If you are able and care to install dev packages then the fix is now
in the dumpling branch and will be in the next release.

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
The easy solution to this is to create a really tiny image in glance (call
it fake_image or something like that) and tell nova that it is the image
you are using. Since you are booting from the RBD anyway, it doesn't
actually use the image for anything, and should only put a single copy of
it in t
Hey Samuel,
Ok, here are the results.

Ok, can you try setting filestore_op_threads to 1 on both cuttlefish
and wip-dumpling-perf (with and with wbthrottle, default wbthrottle
settings). I suspect I created contention in the filestore op threads
(FileStore::lfn_open specifically), and if so setting it to only use 1

Hey folks,
I've just done a brand new install of 0.67.2 on a cluster of Calxeda nodes.
I have one particular monitor that number joins the quorum when I restart
the node. Looks to me like it has something to do with the "create-keys"

Hey Samuel,

I pushed a branch, wip-dumpling-perf. It does two things:
1) adds a config filestore_wbthrottle_enable (defaults to true) to
allow you to disable the wbthrottle altogether
2) causes the wbthrottle when enabled to fdatasync rather than fsync.
Can you rerun the random workload with that branch with

Ah thanks, Brian. I will do that. I was going off the wiki instructions on
performing rados benchmarks. If I have the time later, I will change it
there.

Just to clarify this point: the new config option contorls some debugging

This is an imporant point release for Dumpling. Most notably, it fixes a

Can you confirm you are using the --no-cleanup flag with rados write? This
will ensure there is actually data to read for subsequent seq tests.

Once the cluster is created on Ceph server nodes with MONs and OSDs on it
you have to copy the config + auth info to the clients:

We are using RBD for most of our VM images and volumes. But, if you spin
