Hi Eugen.
Just tried everything again here by removing the /sda4 partitions and
letting it so that either salt-run proposal-populate or salt-run state.orch
ceph.stage.configure could try to find the free space on the partitions to
work with: unsuccessfully again. :(
Just to make things clear:
Hi,
I created a ceph cluster manually (not using ceph-deploy). When I reboot
the node the osd's doesn't come backup because the OS doesn't know that it
need to bring up the OSD. I am running this on Ubuntu 1604. Is there a
standardized way to initiate ceph osd start on node reboot?
"sudo start
You need to re-deploy OSDs for bluestore_min_alloc_size to take effect.

You could probably cut the overhead in half with the inline data
feature:
http://docs.ceph.com/docs/master/cephfs/experimental-features/#inline-data
However, that is an experimental feature.
CephFS is unfortunately not very good at storing lots of small files
in a storage-efficient manner :(
We're glad to announce the next point release in the Luminous v12.2.X
stable release series. This release contains a range of bugfixes and
stability improvements across all the components of ceph. For detailed
release notes with links to tracker issues and pull requests, refer to

This was the issue (could not create the pool, because it would have
exceeded the new (luminous) limitation on pgs /osd.

Instead of manually weighting the OSDs, you can use the mgr module to
slowly add the OSDs and balance your cluster at the same time. I believe
you can control the module by telling it a maximum percent of misplaced
objects, or other similar metrics, to control adding in the OSD, while also
I was confused what could be causing this until Janne's email. I think
they're correct that the cluster is preventing pool creation due to too
many PGs per OSD. Double check how many PGs you have in each pool and what
your defaults are for that.

Are you planning on using bluestore or filestore? The settings for
filestore haven't changed. If you're planning to use bluestore there is a
lot of documentation in the ceph docs as well as a wide history of
questions like this on the ML.

Hello
We are trying to use cephfs as storage for web graphics, such as
thumbnails and so on.
Is there any way to reduse overhead on storage? On test cluster we have
1 fs, 2 pools (meta and data) with replica size = 2
objects: 1.02 M objects, 1.1 GiB
usage: 144 GiB used, 27 GiB / 172

Hello Lothar,
Thanks for your reply.

By pure chance 15 pgs are now actually replicated to all 3 osds, so they
have enough copies (clean). But the placement is "wrong", it would like
to move the data to different osds (remapped) if possible.

12.2.8 just went out. I think that Adam or Radoslaw might have some
It's mds_beacon_grace. Set that on the monitor to control the
replacement of laggy MDS daemons, and usually also set it to the same
value on the MDS daemon as it's used there for the daemon to hold off
on certain tasks if it hasn't seen a mon beacon recently.

Good morning folks,
As a newbie to Ceph yesterday was the first time I've configured my
CRUSH map, added a CRUSH rule and created my first pool using this rule.
Since then I get the status HEALTH_WARN with the following output:

We're going to reproduce this again in testing (12.2.8 drops right between our
previous testing and going production) and compare it to 12.2.7. Will update
with our findings soon. :)
