Hello,
I have a two pools (default and sas).
Is it able to push osd to non default pool after restart without setting
crushmap?
Thanks.

Thanks Sage for the quick response!
We are using firefly (v0.80.4 with a couple of back-ports). One observation we
have is that during peering stage (especially if the OSD got down/in for
several hours with high load), the peering OPs are in contention with normal
OPs and thus bring extremely l

Hello Cephers,
During our testing, I found that the filestore throttling became a limiting
factor for performance, the four settings (with default value) are:
filestore queue max ops = 50
filestore queue max bytes = 100 << 20
filestore queue committing max ops = 500
filestore queue committing
Shot in the dark: try manually deep-scrubbing the PG. You could also try
marking various osd's OUT, in an attempt to get the acting set to include
osd.25 again, then do the deep-scrub again. That probably won't help
though, because the pg query says it probed osd.25 already... actually , it
doesn

We have been running several rounds of benchmarks through the Rados
Gateway. Each run creates several hundred thousand objects and similarly
many containers.
The cluster consists of 4 machines, 12 OSD disks (spinning, 4TB) — 48
OSDs total.
After running a set of benchmarks we renamed the pools us
I'm not sure on RedHat, but on Ubuntu, /etc/init/ceph-osd.conf calls
ceph osd crush create-or-move. Try adding some logging to that script,
something like
echo "Create or move OSD $id weight ${weight:-${defaultweight:-1}} to
location $location" >> /tmp/ceph-osd.log
You probably want more detail
I would like to add that removing log files (/var/log/ceph is also
removed on uninstall) is also a bad thing.
My suggestion would be to simply drop the whole %postun trigger, since
it does only these two very questionable things.
Thanks,
Erik.

Current version of RPM spec for Ceph removes the whole /etc/ceph
directory on uninstall:
https://github.com/ceph/ceph/blob/master/ceph.spec.in#L557-L562
I don't think contents of /etc/ceph is disposable and should be
silently discarded like that.

Hello,
given small test cluster, following sequence resulted to the inability
to join back for freshly formatted OSD:
- update cluster sequentially from cuttlefish to dumpling to firefly,
- execute tunables change, wait for recovery completion,
- shut down single osd, reformat filestore and journ

I wanted to let the group know that I just completed a relatively painless IP
address transition of a 3-node cluster from a flat allocated IP space to one
using a dedicated (and different) network space for the "public" and "cluster"
networks.
This includes changing the block-serving address o

You're right that the command does seem to complete. Haven't yet determined if
its an actual problem or just bad output.

When I had PGs stuck with down_osds_we_would_probe, there was no way I
could convince Ceph to give up on the data while those OSDs were down.
I tried ceph osd lost, ceph pg mark_unfound_lost, ceph pg force_create_pg.
None of them would do anything.
I eventually re-formatted the down OSD, and brou

We are trying to install cephFS using puppet on all the ODS nodes, as well as
