Hi all,
We're trying to spread data in our ceph cluster as much as possible,
that is pick different racks, then different hosts, then different OSDs.
It seems to work fine as long as there are enough buckets available,
but if we ask for more replicas than we have racks, for instance, the

I'm trying to use Ceph FS as glance's backend.
I have mount Ceph FS at glance machine. And edit /etc/glance/glance-api.conf to
use the mounted directory.
But when I upload the image as I used to, I met the error:
Request returned failure status.

Any reason you have chosen to use CephFS here instead of RBD for
direct integration with Glance?

Exporting the CephFS via Samba (Winbind/idmap_ad authenticated to Active

Hey Igor,
Currently there are no plans to develop a OS X or Windows-specific
client per se. We do provide a number of different ways to expose the
cluster in ways that you could use it from these machines, however.
The most recent example of this is the work being done on tgt that can

Hadoop running on Ceph uses the libcephfs user-space library to talk directly
to the file system, as opposed to running through the kernel or FUSE client.

Can you post your updated core-site.xml? I've seen this error before when I
used the URI: ceph:// as opposed to ceph:///.

No, hadoop data is not located in /mnt/ceph/wc, but now i copied the data
into /user/varunc/wc, which cntains the hadoop data. However, the
MR-wordcount example still is not working. Its stuck with this output:
varunc@varunc4-virtual-machine:~$ time /usr/local/hadoop/bin/hadoop jar
hadoop*examples
Getting closer! I suggest checking the log files for your job tracker and all
of your task tracker nodes to see if any of them are having troubles.

Thanks for reply!
Actually I would like found some way to use one large salable central
storage across multiple PC and MAC. CephFS will be most suitable here, but
you provide only Linux support.
Really no planning here?

Hi Patrick,
We actually already tried that before (get three from racks, then the 4th
from hosts). What we ended up with was a pg that was supposed to go
on the same osd twice … so we rolled back in the end :)
Then we thought it might be better to ask how to do this as the scenario

Task tracker is running on both the nodes, and is giving the same error on
both of them (and I am able to run hadoop fs -ls on both). I am running
hadoop as the same user, varunc, and I guess LD_LIBRARY_PATH has been setup
correctly:
varunc@varunc4-virtual-machine:/usr/local/hadoop$ echo $LD_LIBRA
Are you setting LD_LIBRARY_PATH in your bashrc? If so, make sure it is set at
the _very_ top (before the handling for interactive mode, a common problem with
stock Ubuntu setups).
Alternatively, set LD_LIBRARY_PATH in conf/hadoop-env.sh.

Hi Noah,
Setting LD_LIBRARY_PATH in conf/hadoop-env.sh seems to have done the trick.

I think object storage (using the Swift-compatible Ceph Object
Gateway) is the preferred mechanism for a Glance backend.

..to be more precise, I should have said: object storage has been the
preferred mechanism of late in Openstack, but RBD makes more sense due
to the copy-on-write facility. Either way, either the Ceph object
gateway or Ceph RBD makes more sense than CephFS currently.
