We @ gocept are currently in the process of developing backy, a new-style

The tool is not quite finished, but it is making rapid
Hi guys,
Was wondering if 0.80.2 is coming any time soon? I am planning na upgrade from
Emperor and was wondering if I should wait for 0.80.2 to come out if the
release date is pretty soon. Otherwise, I will go for the 0.80.1.
Cheers

Hi Wido, thanks for answers - I have mons and OSD on each host... server1:
mon + 2 OSDs, same for server2 and server3.
Any Proposed upgrade path, or just start with 1 server and move along to
others ?
Thanks again.

I am following step by step the test intallation, and checking some

Wido,
one final question:
since I compiled libvirt1.2.3 usinfg ceph-devel 0.72 - do I need to
recompile libvirt again now with ceph-devel 0.80 ?
Perhaps not smart question, but need to make sure I don't screw something...
Thanks for your time,

Hi,
I have a ceph cluster setup (with 45 sata disk journal on disks) and get only
450mb/sec writes seq (maximum playing around with threads in rados bench) with
replica of 2
Which is about ~20Mb writes per disk (what y see in atop also)
theoretically with replica2 and having journals on disk

HI,
Ceph.conf:
osd journal size = 15360
rbd cache = true
rbd cache size = 2147483648
rbd cache max dirty = 1073741824
rbd cache max dirty age = 100
osd recovery max active = 1
osd max backfills = 1
osd mkfs options xfs = -f -i
when I see the function OSD::OpWQ::_process . I find pg lock locks the whole
function. so when I use multi-thread write the same object , so are they must
serialize from osd handle thread to journal write thread ?

Hi,
I'm trying to make multi part upload work. I'm using ceph
0.80-702-g9bac31b (from the ceph's github).
I've tried the code provided by Mark Kirkwood here:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-October/034940.html
But unfortunately, it gives me the error:
I was at this issue this morning. It seems radosgw requires you to have a
pool named '' to work with multipart. I just created a pool with that name
rados mkpool ''
either that or allow the pool be created by the radosgw...

It looks like you're just putting in data faster than your cluster can
handle (in terms of IOPS).
The first big hole (queue_op_wq-reached_pg) is it sitting in a queue
and waiting for processing. The second parallel blocks are
1) write_thread_in_journal_buffer-journaled_completion_queued, and
that
The PG in question isn't being properly mapped to any OSDs. There's a
good chance that those trees (with 3 OSDs in 2 hosts) aren't going to
map well anyway, but the immediate problem should resolve itself if
you change the choose to chooseleaf in your rules.

Do those logs have a higher debugging level than the default? If not
nevermind as they will not have enough information. If they do however,
we'd be interested in the portion around the moment you set the tunables.
Say, before the upgrade and a bit after you set the tunable. If you want to
