Hello,
As others said, it depends on your use case and expected write load.
If you search the ML archives, you will find that there can be SEVERE
write amplification with Ceph, something to very much keep in mind.
You should run tests yourself before deploying things and committing to a

Any update on this fix getting merged? We suspect other crashes based on

Hi All,
Is there a good documentation on Ceph Testing.
I have the following setup done, but not able to find a good document to start
doing the tests.

Hi all,
Documentation explains how to remove the cache pool:
http://ceph.com/docs/master/rados/operations/cache-tiering/
Anyone know how to remove the storage pool instead? (E.g. the storage pool
has wrong parameters.)
I was hoping to push all the objects into the cache pool and then rep
Hi Zhang,
Thanks for the pointer. That page looks like the commands to set up the
cache, not how to verify that it is working.
I think I have been able to see objects (not PGs I guess) moving from the

I tried this a while back. In my setup, I exposed an block device with

problem I had at the time (maybe 6-12 months ago) was that owncloud

Raj,
The note is still valid, but the filesystem is getting more stable all the
time. Some people are using it, especially in an active/passive
configuration with a single active MDS. If you do choose to do some
testing, use the most recent stable release of Ceph and the most recent

thank all for the very very helpful advices.
Now i have reinstalled my ceph cluster.

Dear all,
we would like to use ceph as a a primary (object) storage for owncloud.
Did anyone already do this? I mean: is that actually possible or am I

As I understood I have to use radosGW in swift "flavor", but what about
s3 flavor?
I cannot find anything "official" so hence my question.

Although the documentation is not great, and open to interpretation, there

With it you should be able to simulate your use case, and generate number
