Hello,
As I know, radosgw calculates MD5 of the uploaded file and compares it with
MD5 provided in header.
Is it possible to get calculated MD5 of uploaded file directly from Rados.
We want to keep it as a file attribute for future use.
How radosgw calculates MD5? Is it realtime block by block c

You're right. I checked the other servers, and noticed the server that has

I can't figure what is different. All servers are copied from one VM. I

I'm testing ceph for storing a very large number of small files. I'm
seeing some performance issues and would like to see if anyone could offer
any insight as to what I could do to correct this.
Some numbers:

Bill,
I've run into a similar issue with objects averaging ~100KiB. The
explanation I received on IRC is that there are scaling issues if you're
uploading them all to the same bucket because the index isn't sharded. The
recommended solution is to spread the objects out to a lot of buckets.

Bryan,
Good explanation. How's performance now that you've spread the load
over multiple buckets?

Is static3 a bucket that you created before the upgrade? Can you test
it with newly created buckets? Might be that you're hitting some other

In the source tree, I see an example source of extending ceph ... is there
a client also that I can test it out with ?

So far I haven't seen much of a change. It's still working through
removing the bucket that reached 1.5 million objects though (my guess is
that'll take a few more days), so I believe that might have something to do
with it.

We've actually done the same thing, creating 65k buckets and storing 20-50

Just for clarification, distributing objects over lots of buckets isn't
helping improve small object performance?
The degradation over time is similar to something I've seen in the past,
with higher numbers of seeks on the underlying OSD device over time. Is
it always (temporarily) resolved w

I notice under HOSTNAME RESOLUTION section the use of 'host -4
{hostname}' as a required test, however, in all my trial deployments
so far, none would pass as this command is a direct DNS query, and
instead I usually just add entries to the host file.
Two thoughts, is Ceph expecting to only do DNS
