Hi
Having previously had problems during startup with "creating keys" (otherwise a
working setup) one one node when using mkcephfs, i have given ceph-deploy a try
and get stuck on what feels like the same step.
Ceph version is 0.61.7 and OS is centos 6.4.
Steps i have done is:
#ceph-deploy new
Hi all,
I am trying to change the mon osd nearfull / full ratio. Currently, my
settings are these:
# ceph pg dump | head
full_ratio 0.95
nearfull_ratio 0.85
I edited ceph.conf file and added the configuration options, following
instructions at
http://ceph.com/docs/master/rados/configuration/mon
Thanks! Neil.
If cephfs and krbd are not used, is the default kernel working well with only
QEMU/kvm/librbd? AFAIK, librbd doesn't have dependency on the kernel version,
right?

Hi Mathias,
Have you tried these steps and sticking to the slow interfaces? I would be
curious to see if this is just a problem of how those interfaces are able
to talk to each other.

Neil,
What's the difference between your custom qemu packages and the official ones?
There are two kinds of packages in it:
qemu-kvm-0.12.1.2-2.355.el6.2.cuttlefish.async.x86_64.rpm
qemu-kvm-0.12.1.2-2.355.el6.2.cuttlefish.x86_64.rpm
What's the difference between them? Does the "async" versi

Greg,
Thanks for the hints. I looked through the logs and found OSD's
with RETRY's. I marked those "out" (marked in orange) and let ceph
rebalance. Then I ran the bench command.
I now have many more errors than before :-(.

We've tagged and pushed out packages for another release candidate for
Dumpling. At this point things are looking very good. There are a few
odds and ends with the CLI changes but the core ceph functionality is
looking quite stable. Please test!
Packages are available in the -testing repos:
Yes, use the async one. We will be getting rid of the non-async one soon.
The default Qemu packages in 6.4 doesn't link to librbd whereas these
custom packages have been built explicitly with the link.
Hoping to announce some positive news soon about why this should become
much simpler in 6.5 and
Hi,
I think the high CPU usage was due to the system time not being right. I
activated ntp and it had to do quite big adjustment, and after that the
high CPU usage was gone.
Anyway, I immediately ran into another issue. I ran a simple benchmark:
# rados bench --pool benchmark 300 write --no-clean
My Mon store.db has been at 220GB for a few months now. Why is this and how can
I fix it? I have one monitor in this cluster and I suspect that I can't add
monitors to the cluster because it is too big. Thank you.

220GB is way, way too big. I suspect your monitors need to go through a
successful leveldb compaction. The early releases of Cuttlefish suffered
several issues with store.db growing unbounded. Most were fixed by
0.61.5, I believe.
You may have luck stoping all Ceph daemons, then starting the m
Thanks for the reply, but how can I fix this without an outage?
I tired adding 'mon compact on start = true' but the monitor just hung.
Unfortunately this is a production cluster and can't take the outages (I'm
assuming the cluster will fail without a monitor). I had three monitors I was

Thank you Joao,
I'll get you any information you need.
I can tell you that I've restarted the mon few times and it does seem to change
disk usage.
I just ran 'ceph-mon -i 2 --compact' on my monitor, see how that looks in the
morning.

All software has lots of teeny tiny usability issues. The ones that never
really get in your way but make everything a bit more difficult to do. We
call them “paper cuts”, and Ceph has a few of them.
We’d like to start collecting a list of the “paper cuts” that make
Ceph hard to learn and use.
Yes, I have changed them on all monitors (3).
Is reading the nearfull off 'ceph pg dump' the correct way of viewing?
