Hi ceph-users,
I am trying S3-compatible API of ceph, but meet following issues:
1. x-amz-acl: public-read-write
I upload an object with public-read-write acl. Then I can get this object
directly without access key.
curl -v -s http://radosgw_server/mybucket0/20131015_1
...
HTTP/1.1 200

hi all!
my ceph is 0.62, and I want to build it wit hadoop.
./configure -with-hadoop
but it return jni.h not found.
I found the jni.h in /usr/java/jdk/include/jni.h
how can I fix this Problem！

Hi All,
Does anyone know if it'll be possible to use the radosgw admin API when
using keystone users? I suspect not due to the user requiring specific
caps, however it'd be great if someone can validate (I'm still running
v0.67.4 so can't play with this much).
Thanks!

Hello,
when i set a read permission for all users to the bucket i read only the
content of the bucket but i received access denied for all directory
and sub-directory inside this bucket.
Where i wrong???
Many thanks

Hi all,
There has been some confusion the past couple days at the CHEP conference
during conversations about Ceph and protection from bit flips or other subtle
data corruption. Can someone please summarise the current state of data
integrity protection in Ceph, assuming we have an XFS backend
The --with-hadoop option has been removed. The Ceph Hadoop bindings are now
located in git://github.com/ceph/hadoop-common cepfs/branch-1.0, and the
required CephFS Java bindings can be built from the Ceph Git repository
using the --enable-cephfs-java configure option.

Write performance for both xfs mounts is similar ~12MB/s

I wouldn't go so far as to say putting a vm in a file on a networked filesystem
is wrong. It is just not the best choice if you have a ceph cluster at hand,
in my opinion. Networked filesystems have a bunch of extra stuff to implement
posix semantics and live in kernel space. You just need

Dieter,
Creating snapshots using cephfs is quite simple...all you need to do is create
a directory (mkdir) inside the hidden '.snap' directory.
After that you can list (ls) and remove them (rm -r) just as you would any
other directory:
smiley@server1:/mnt/cephfs$ cd .snap

At CERN, we have had cases in the past of silent corruptions. It is good to be

Thank you Sage for the thorough answer.
It just occurred to me to also ask about the gateway. The docs explain that one
can supply content-md5 during an object PUT (which I assume is verified by the
RGW), but does a GET respond with the ETag md5? (Sorry, I don't have a gateway

Andrija,
You can use a single pool and the proper CRUSH rule
step chooseleaf firstn 0 type host
to accomplish your goal.

- stop a ceph-osd daemon, then
- ceph-osd --flush-journal
well, nice one :)
*step chooseleaf firstn 0 type host* - it is the part of default crush map
(3 hosts, 2 OSDs per host)
It means: write 3 replicas (in my case) to 3 hosts...and randomly select
OSD from each host ?
I already read all the docs...and still not sure how to proceed...

Hello Michael,
Thanks for the reply. It seems like ceph isn't actually mounting the rbd
to the vm host which is where I think I was getting hung up (I had
previously been attempting to mount rbds directly to multiple hosts and as
you can imagine having issues).
Could you possible expound on why

I may be wrong, but I always thought that a weight of 0 means don't put

higher weights anyway:
