Hi everyone.
I'm wondering - is there way to backup radosgw data?
What i already tried.
create backup pool - copy .rgw.buckets to backup pool. Then i delete
object via s3 client. And then i copy data from backup pool to
.rgw.buckets. I still can't see object in s3 client, but can get it via
http
Thank you for your reply
I had read the 'mds crashing' thread and i dont think im seeing that bug

starting mds : http://pastebin.com/dbk0uLYy
Here is the last part of log:

write correctly.

Hi,
We did it the other way around instead, defining a period where the load is
lighter and turn off/on backfill/recover. Then you want the backfill values
to be the what is default right now.
Also, someone said that (think it was Greg?) If you have problems with
backfill, your cluster backing

I like the idea of turning the defaults down. During the ceph operators
session at the OpenStack conference last week Warren described the behavior
pretty accurately as Ceph basically DOSes itself unless you reduce those
settings. Maybe this is more of a problem when the clusters are small?

Sam,
We are seeing some good client IO results during recovery by using the
following values..
osd recovery max active = 1
osd max backfills = 1
osd recovery threads = 1
osd recovery op priority = 1
It is all flash though. The recovery time in case of entire node (~120 TB)

Hi,
I have setup a cluster with newstore functionality and see that file sized
of 100KB are stored in the DB and files 100KB are stored in fragments
directory.
Is there a way to change this threshold value in ceph.conf?

In the end this came down to one slow OSD. There were no hardware
issues so have to just assume something gummed up during rebalancing and
peering.
