I was getting roughly the same results of your tmpfs test using
spinning disks for OSDs with a 160GB Intel 320 SSD being used for the
journal. Theoretically the 520 SSD should give better performance
than my 320s.
Keep in mind that even with balance-alb, multiple GigE connections
will only be use

Hi Sage,
I've been trying to solve the issue mentioned in tracker #2047, which I
think is the same as I described in
http://www.spinics.net/lists/ceph-devel/msg05824.html
The attached patches seem to fix it for me. I also attempted to
address the local search issue you mentioned in #2047.
I
For the first few rejections or collisions, we'll retry the descent to
keep objects spread across the cluster. After that, we'll fall back
to exhaustive search of the bucket to avoid trying forever in the event
a bucket has only a few in items and the hash doesn't do a good job of
finding them.
S
When an object is re-replicated after a leaf failure, the remapped replica
ends up under the bucket that held the failed leaf. This causes uneven
data distribution across the storage cluster, to the point that when all
the leaves of a bucket but one fail, that remaining leaf holds all the
data fro
After I run the 'ceph osd out 123' command, is there a specific ceph
command I can poll so I know when it's OK to kill the OSD daemon and
begin the reformat process?

This short series adds the use of read_partial() in a few places
that it is not already. It also gets rid of the in/out "to"
argument (which continues to cause confusion every time I see it),
using an in-only "end" argument in its place.

There are two blocks of code in read_partial_message()--those that
read the header and footer of the message--that can be replaced by a
call to read_partial(). Do that.

read_partial() always increases whatever "to" value is supplied by
adding the requested size to it. That's the only thing it does with
that pointed-to value.
Do that pointer advance in the caller (and then only when the
updated value will be subsequently used), and change the "to"
parameter to b
Make the second argument to read_partial() be the ending input byte
position rather than the beginning offset it now represents. This
amounts to moving the addition "to + size" into the caller.

Hi, all
I created Ceph file system using Debian7 of 64bit.
I found that PGs of 'creating' status are never finished.

Dear List,
i'm doing a testsetup with ceph v0.46 and wanted to know how fast ceph is.
my testsetup:
3 servers with Intel Xeon X3440, 180GB SSD Intel 520 Series, 4GB RAM, 2x
1Gbit/s LAN each
All 3 are running as mon a-c and osd 0-2. Two of them are also running
as mds.2 and mds.3 (has 8GB RAM ins
OK, here some retests. I had the SDDs conected to an old Raid controller
even i did used them as JBODs (oops).
Here are two new Tests (using kernel 3.4-rc6) it would be great if
someone could tell me if they're fine or bad.
New tests with all 3 SSDs connected to the mainboard.

Hi,
the "Designing a cluster guide"
http://wiki.ceph.com/wiki/Designing_a_cluster is pretty good but it
still leaves some questions unanswered.
It mentions for example "Fast CPU" for the mds system. What does fast
mean? Just the speed of one core? Or is ceph designed to use multi core?
Is multi c

Put the tracepoints after calls to ceph_osdc_start_request,

Hi Alex,
I ran across tracker #2374 today - I've been carrying these two
tracepoint patches for a while. Perhaps you'll find them useful.
Jim Schutt (2):
ceph: add tracepoints for message submission on read/write requests
ceph: add tracepoints for message send queueing and completion, reply

GREAT!
I haven't looked at them but I will as soon as I get the chance.
I don't expect there's any reason not to

Sorry for my late response. I reproduced the above bug with the Linux
kernel 3.3.4 and without using XEN:
uname -a

The trace is shown below:
