Hello, I am from China, I hope you can read my poor english as belows .
We are doing a basic test with ceph and cloudstack.
experimental environment :
1. four ceph-osds running on two nodes(centos6.2),both of them get three 1GB
phisical disks(we build osds on /dev/sdb and /dev/sdc).
so we

Hello!
We got a issue with integration of RadosGW and Keystone. Can you support us?
We have such ceph configuration:
[global]
rgw socket path = /tmp/radosgw.sock
[client.radosgw.gateway]
host = fuel-controller-01
user = www-data
keyring = /etc/ceph/client.radosgw.gateway.key
thank you for your instant reply.
1. so far,we haven't used cache yet.
2. about the version:
qemu--QEMU emulator version 1.4.0 (Debian 1.4.0+dfsg-1expubuntu4)
ceph---ceph version 0.61.4
the xml file of the vm is as belows:
i-2-49-VM
12608
Hi,
I was doing some Bash scripting and I'm not sure if it's me or the
ceph-conf tool.
I'm trying to retrieve the "osd data" dir for osd.0, but that fails
since I haven't declared that variable in the conf file because I'm
using the default setting.
root@data1:~# ceph-conf --name osd.0 --l
Hi,Alex.Here comes the new update:
We apply cache='writeback' to the vm. then the performance improve,however, not
quite much,the speed is 9.9MB/s,increased by 3.9MB/s. any other advise for us?
thanks a lot.
Best regards.

It sounds like you just built a 4GB (or 6GB?) RADOS cluster and then tried
to put 4GB of data into it. That won't work; the underlying local
filesystems probably started having trouble with allocation issues as soon
as you go to 2GB free.

It's the tool. We definitely want a way to find out if a config option is
set or not, but I think patches here would be welcome. :)
You can also look at ceph-disk's get_conf and get_conf_with_default methods
for how I handle this.

If you do

Hi,
We took osd.71 out and now problem is on osd.57.
Something curious, op_rw on osd.57 is much higher than other.
See here: https://www.dropbox.com/s/o5q0xi9wbvpwyiz/op_rw_osd57.PNG
On data on this osd I found:
> data/osd.57/current# du -sh omap/
> 2.3Gomap/
That much higher op_rw on one osd

Thanks Josh. That explains. So I guess right now with Grizzly, you can
only use one rbd backend pool (assume with different cephx key for
different pool) on a single Cinder node unless you are willing to modify
cinder-volume.conf and restart cinder service all
There is almost same problem with the 0.61 cluster, at least with same
symptoms. Could be reproduced quite easily - remove an osd and then
mark it as out and with quite high probability one of neighbors will
be stuck at the end of peering process with couple of peering pgs with
primary copy on it.
Today I have peereng problem not when I put osd.71 out, but in normal CEPH work.

Hmm, osd not died, 1 or more pg stack on peereng on it.

Can you get a pgid from 'ceph health detail' and then do 'ceph pg
query' and attach that output?
Thanks!

Hi, all!
Inktank is preparing a series of Ceph Days this fall in the US and Europe,
intended for users and developers who want to learn about Ceph and meet
other members of the community. Our current working agenda contains a look
into the future of Ceph, stories from real world users, an install
I have only 'ceph healht details' from previous crash.
