Is RBD snapshotting what I'm looking for? Is this even possible?
Yes, you can use rbd snapshoting, export / import
http://ceph.com/dev-notes/incremental-snapshots-with-rbd/
But you need to do it for each rbd volume.
Here a script to do it:

Hi Alexandre,
Thanks for the link! Unless I'm misunderstanding, this is to replicate an
RBD volume from one cluster to another. What if I just wanted to back up a
running cluster without having another cluster to replicate to? i.e. I'd
ideally like a tarball of raw files that I could extract on a

Yes, import is optionnal,
you can simply export and pipe to tar

Hi Sam,
Incomplete usually means the pgs do not have any complete copies. Did
you previously have more osds?
No. But could have OSDs quitting after hitting assert(0 == we got a bad
state machine event), or interacting with kernel 3.14 clients have caused the
incomplete copies?
How can I
Hi,
There is a small bug in the Fedora package for ceph-0.87. Two days ago,
Boris Ranto built the first 0.87 package, for Fedora 22 (rawhide) [1].

This build was a succes, so I took that package and built it for Fedora

Thanks for your presentation this afternoon! Would be great if you
could please share your slides and perhaps go into some more detail
about your modelling of copysets in crush.

Hi there,
I have this situation, where I'm using the same Ceph cluster (with
radosgw), for two different environments, QUAL and PRE-PRODUCTION.
I need different users for each environment, but I need to create the
same buckets, with the same name; I understand there is no way to have
2 buckets

The incomplete pgs are not processing requests. That's where the

You could setup dedicated zones for each environment, and not
replicate between them.
Each zone would have it's own URL, but you would be able to re-use
usernames and bucket names. If different URLs are a problem, you
might be able to get around that in the load balancer or the web
servers. I

Are you referring to manual roll out of ceph osd crush tunables optimal (
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2014-July/041499.html) ?
Can you include a copy of ceph osd tree and your crushmap?
Were the OSDs flapping when you did those queries? pg 6.19 says [0,1] is

You linked to both RDB and CephFS topics. Looks like RDB is covered well
in this thread, but you'll need something else if you want to backup CephFS
(or RadosGW).
CephFS is a normal file POSIX filesystem, so normal backup tools work on
it. Although that can be complicated if you make it large.
Hi,
It was an image import in openstack juno using glance.
It looks like it was the fault of glance after all, as a rados import
was fast (aka normal).
I should open a bug with juno release, as icehouse imports the image normally.
It was an empty pool, no spapshots, no files.
Best regards,
Hi Craig,
We are indeed using both Ceph FS and radosgw. I know I can use tools to
crawl over all the files and copy them someplace else, but wanted to see if
there was a better Ceph-recommended way to backup the pools themselves
which I can then re-import.
*Chris Armstrong*Head of Services
Yes, that`s right guess - crushmap is imagining both OSDs on a single
host, although daemon on the second host was able to act as up/in when
crushmap placed it on a different host, looks as a weird placement
miscalculation during update.

No. For most people, that's not really practical. Where would you export
a 1 PB pool? :-)
CephFS has some nice features that could make a traditional filesystem
backup much more efficient. It rolls the size and last-modified attributes
up the directory tree. If the backup client understood
Thanks Craig! I'll write up some docs/scripts for backing up radosgw and
Ceph FS and share back with the community.

Hello everyone,
I am attempted to setup a two cluster situation for object storage disaster
recovery. I have two physically separate sites so using 1 big cluster isn’t an
option. I’m attempting to follow the guide at:
http://ceph.com/docs/v0.80.5/radosgw/federated-config/
One region two zones is the standard setup, so that should be fine.
Is metadata (users and buckets) being replicated, but not data (objects)?
Let's go through a quick checklist:
- Verify that you enabled log_meta and log_data in the region.json for
the master zone
- Verify that

My ceph cluster needs to have two rados gateway nodes eventually interfacing

Thanks much.
Sounds like you needed osd 20. You can mark osd 20 lost.
