You can do this with the admin socket:

Hi Community,
I have read the documentation to know crush map as well as
inserting new crushmap, But I have qn that even after writing own rule
for data placement how we can apply it for data placement? in short
how to utilize newly specified rule when new data insertion is
executed.
Hi,
I have a problem that newly copied files disappear from the FS after a few
minutes. The only suspicious log entries look like this:

I see messages like this

Hi Sage and ceph-developers,
I reproduced the error again and captured file descriptors and log information.
I've quoted them below. Here is a brief summary:
I have ceph 0.48 running on a single mulitprocessor node. I have two clients
that have mounted the cephfs over infiniband (same error happe

Hi, all!
One of the most important parts of Inktank's mission is to spread the
word about Ceph. We want everyone to know what it is and how to use
it.
In order to tell a better story to potential new users, I'm trying to
get a sense for today's deployments. We've spent the last few months
talking
My use of Ceph is probably pretty unique in some of the aspects of where/how
I'm using it. I run an IT department for a medium-sized engineering firm. One
of my goals is to try to make the best possible use of the hardware we're
deploying to users' desktops. Often times users cannot get by wi
Hi Nick,
All I have to say, is that is totally awesome and scary at the same time. :)
Glad to hear that it recovers well when people shut their desktops off!

Our use of Ceph started pretty recently (this summer). We only use
rados together with the radosgw. We moved from another distributed
storage solution that had failed us more than once and we lost data.
Since the old system had an http interface (not S3 compatible though)
we looked around for anoth
We actually ask people to not shut off their desktops, so it doesn't happen
very often :-). Also, I run the MDS and MON systems inside my datacenter, so
only the OSDs are out there on the desktops.

John,
I'd be really interested to hear how Btrfs goes over time. I tried it out a
few kernel versions ago and regretted it - lost some data after using it.
Hopefully the stability is better than it was before, and inline compression is
always great!

Hi,
i use ceph to provide storage via rbd for our virtualization cluster delivering
KVM based high availability Virtual Machines to my customers. I also use it
as rbd device with ocfs2 on top of it for a 4 node webserver cluster as shared
storage - i do this, because unfortunatelly cephfs is not

Hi
Just FYI, on the NFS integration front. A pnfs files (RFC5661)-capable NFSv4
re-exporter for Ceph has been committed to the Ganesha NFSv4 server development
branch. We're continuing to enhance and elaborate this. We have had on our
(full) plates for a while to return Ceph client library c
I'm looking at building a hbase/bigtable style key-value store on top
of Ceph's omap abstraction of LevelDB. The plan is to use this for log
storage at first. Writes use libradospp, with individual log lines
serialized via message-pack and then stored as omap values. Omap keys
are strings which gr
We had a similar idea on our mind for a while now. The thought was to
add a key value support that leverages omaps and get it exposed
through the RESTful rados gateway. Having a real world use for it will
certainly help in understanding the requirements.

Well I've used Btrfs on and off for two years now I think - in less
critical situations though (at home, on testing equipment at work and
on easily rebuildable systems). I've been bitten several times before
so I know there've been serious problems with it.
With Kernel 3.5 I had a pretty good feeli
