Hi,
Ceph uses other ports also for other daemons like OSD and MDS. Please
refer to
http://docs.ceph.com/docs/jewel/rados/configuration/network-config-ref/
This might help you to resolve the issue.
Thanks.

Hello all,
We have a small 160TB Ceph cluster used only as a test s3 storage repository
for media content.
Problem
Since upgrading from Firefly to Hammer we are experiencing very high OSD memory
use of 2-3 GB per TB of OSD storage - typical OSD memory 6-10GB.
We have had to increase swap space
Dear Laizer,
Oh, I got it. the rbd was created successfully after I disabled the
firewall.
However, when the firewall is enabled and the 6789 port is allowed, the
authentication error is occurred.
Is there any other port?

Hi,
context (i.e. what we're doing): We're migrating (or trying to) migrate off

foo/01/
foo/0b/<0b>

Yeah, I am not sure why no one else is having the same issues. Anyway, had a

Thanks, that's just what I needed.
For others: I found some information in the Red Hat Ceph Storage 2
documentation. This includes the command "radosgw-admin rename"
which I was unaware of for single-site to multi-site.
(It doesn't seem very encouraging about Hammer to Jewel multisite

That's interesting, as I am getting the exact same errors after
upgrading from Hammer 0.94.9 to Jewel 10.2.3 (on ubuntu 14.04).
I wondered if it was the issue referred to a few months ago here, but
I'm not so sure, since the error returned from radosgw-admin commands is

Thanks Kefu!
Downgrading the mons to 0.94.6 got us out of this situation. I appreciate
you tracking this down!

Generally you need to create a new realm, and add the 'default'
zonegroup into it. I think you can achieve this via the 'radosgw-admin
zonegroup modify' command.
The zonegroup and zone can be renamed (their id will still be
'default', but you can change their names).

Thanks for your response. But yes, the netwerk is OK.
But i will double check to be sure.
Then again, If I copy other (big) files from the same client everything
works without any issues. The problem is isolated to a specific file.
With a mis-configured network I would see this kind of issues cons
Hi,
are you sure, that the network is OK ?
Stuff like this can happen if somewhere in between the MTU size is
different.
So make sure, that all public ceph nic's have the same MTU as the
client, and also every switchport has the same MTU in between.

Hi all,
I have an issue that when I copy a specific file with ceph-fuse on
cephfs (within the same directory) it stalls after a couple of GB of
data. Nothing happens. No error, it just "hangs".
When I copy the same file with the cephfs kernel client it works without
issues.
I'm running Jewel 10.

Hi,
Faced with the similar problems on the CentOS7 - looks like condition

Update to 3.2 solve my problem (from 3.1 from the CentOS7 base):

how did you set the parameter ?
editing ceph.conf only works when you restart the osd nodes.
but running something like
ceph tell osd.* injectargs '--osd-max-backfills 6'
would set all osd's max backfill dynamically without restarting the osd.
and you should fairly quickly afterwards see more
