Hello,
I'm trying to upload a multipart file to the radosgw (v 0.67.1) using the
Amazon S3 API (v 1.5.3) following the example in

The upload seems to go well, there are no errors in the logs and if I use

Thank you Greg. It makes sense, that ceph-fuse will work this way.
I am experiencing this problem for example when I run rsync on folder with lot
of small files in ceph (~300GB in 10kB files). Ceph is during that very slow
and everything crash like domino.
I will look into other ways of reading
Is there an issue ID associated with this? For those of us who made the

Hi All,
I'm deploying a small Ceph cluster (1 MON, 4 OSD, 1MDS) using a modified
version of the ENovance Puppet modules
(https://github.com/enovance/puppet-ceph) (I'm using Dumpling on Ubuntu 12.04
instead of Bobtail on Debian).
All goes well until themes is deployed and I get the following er

Sounds like the puppet scripts haven't put the client.admin keyring on that
node, or it's in the wrong place.
Alternatively, there's a different keyring they're supposed to be using but
it's not saying so in the command.

Hi,
Is it possible to have more than one CephFS filesystem per Ceph cluster?
In the default configuration, a ceph cluster has got only one filesystem, and
you can mount that or nothing. Is it possible somehow to have several distinct
filesystems per cluster, preferably with access controls that

I had a good run on the production-cluster with it and unfortunately, it

There haven't been any significant osd side changes that I can think

Files are subdivided to folders by 1000 in each folder (/img/10/21/10213456.jpg

I just discovered, that it would make much more sense to read images in

shouldn't affect connected clien

In that case the stability issues are probably with your OSDs being
overloaded by write requests that aren't being appropriately
Hey Samuel,
CPU-usage still seems a bit higher, but not always equally on every OSD.
I profiled the node with the most CPU-usage on the OSD. Note the
libleveldb-related stuff right at the top. The Cuttlefish-OSD doesn't
show those at all. Could those be related to the problem?

Try it again in the reverse order, I strongly suspect caching effects.

Fantastic! Thank you for the quick response. I'm available if you need any

Hey Samuel,
I repeated the same test several times before my post and just now 2
more times. It holds up and is also repeatable in reverse order, with
the same results. Remember, I restart all OSDs between tests, so any
caches should get destroyed and besides, I'm writing. That shouldn't

Hi guys,
I'm a newbie in ceph. Wonder if I can use 2~3 LVM disks on each server,
total 2 servers to run a quick ceph clustering tests.
Thanks!

You'd need to unmount the fs to actually clear the cache. Did you see
a significant difference in load between the runs? To confirm, the
rbd client is dumpling the entire time?

I am dumb. There *has* been a change in the osd which can account for
this: the wbthrottle limits. We added some logic to force the kernel
to start flushing writes out earlier, normally a good thing. In this
case, it's probably doing an fsync every 500 writes.
Can you run 3 tests?

I think the rbd cache one you'd need to run for a few minutes to get
meaningful results. It should stabilize somewhere around the actual
throughput of your hardware.
Hmm, 10k ios I guess is only 10 rbd chunks. What replication level
are you using? Try setting them to 1000 (you only need to
