From my experience, don't start with their storage server. Instead look
at "ordinary" models.
Instead of having 1 server with 12 disk bays it is often better to hav

Hi,
Seems more and more that ceph is out in the wild - people are using it for
production, development speeds up etc.
Still how can one pick the configuration suiting his needs?
For example, we wish to replace older SAN IBM/HP storages with ceph, we
know iops, bandwidth capabilities of those, bu

For me it progressed up to ceph reinstall with repair data from backup (I help

How do I set the weight for OSDs? I have 4 OSDs I want to create
with very low weight (<1) so they are never used if any other OSDs
are added subsequently (and would like to avoid placement groups).
These OSDs have been created with default settings using the manual
OSD add procedure as per ceph d

Make sure the ceph-mon daemons have been restarted so that they are

Some scrub errors showed up on our cluster last week. We had some issues with
host stability a couple weeks ago; my guess is that errors were introduced at
that point and a recent background scrub detected them. I was able to clear
most of them via "ceph pg repair", but several remain. Based on
Look at 'ceph osd tree'. The weight value in 'ceph osd dump' output is
the in/out correction, not the crush weight.

Doh. Thanks.
Is there a difference between:
ceph osd crush set 0 2 root=default
and
ceph osd crush reweight osd.0 2
?

Hello,
I'm deploying a test cluster on 0.61.2 version between two nodes (OSD/MDS),
and another (MON).
I have a problem making my cluster grow, today i've added an OSD into a

Hi all,
Well, looks like DragonDisk (http://www.dragondisk.com/) deal with RRDNS
well, it just run with both RGWs ;)
But what actually I need to know now is why RGW not start at boot time with
"Initialization timeout, failed to initialize" error in logs. It
run successful by hands after that.

If I want to remove an osd, I use 'ceph out' before taking it down, i.e.
stopping the OSD process, and removing the disk.
How do I (preferably programatically) tell when it is safe to stop the OSD
process? The documentation says 'ceph -w', which is not especially helpful, (a)

What does your crushmap look like? There's a good chance you're
choosing first hosts, and then OSDs, which means you can't come up with
3 replicas (because there are only two hosts).
Try:
ceph -o my.crush.map osd getcrushmap
crushtool -i my.crush.map --test --output-csv
and then look at the .
Hi Sean:
It looks to me like this is the result of the simple-minded[1] strategy
for allocating a return buffer for rbd_list():
ibuf_len = 1024;
ibuf = malloc(ibuf_len);
actual_len = rbd_list(ioctx, ibuf, &ibuf_len);
if (actual_len < 0) {

Yes, with the proviso that you really mean "kill the osd" when clean.
Marking out is step 1.
