Hi all,
approaching ceph today for the first time, so apologize for the basic
questions I promise I will do all my homework :-)
Following the documentation "storage cluster quick start" I am soon
stuck with the issue below while creating a first mon:

I faced similar kind of errors and these are really annoying. I tried this and

give you more strength.

Do you suggest a RAID1 for the OS partition

Hi Sahana,
Did you already create any osd? With the osd prepare and activate command?

Did you set up the corresponding directories: /var/lib/ceph/osd/ceph-0,
and called mkcephfs before?
You can also try starting osd manually by 'ceph-osd -i 0 -c
/etc/ceph/ceph.conf', then 'pgrep ceph-osd' to see if they are there,
then 'ceph -s' to check the health.

Hi guys,
I won’t do a RAID 1 with SSDs since they both write the same data.
Thus, they are more likely to “almost” die at the same time.
What I will try to do instead is to use both disk in JBOD mode or (degraded
RAID0).
Then I will create a tiny root partition for the OS.
Then I’ll still have

I mean, I have OSD's and MON's running now, but I see no mention of them in the
current config file (/etc/ceph/ceph.conf) so backing that file up would not
allow me to see where monitors/objectstores/journals where placed. Is there a
nifty command that allows me to push these defaults to somethi
Another option is to run journals on individually presented SSDs, in a
5:1 ratio (spinning-disk:ssd) and have the OS somewhere else. Then the
failure domain is smaller.
Ideally implement some way to monitor SSD write life SMART data - at
least it gives a guide as to device condition compared

Ah. So that warning compares the objects per pg in that pool vs the
objects per pg in the entire system, and if there is too much of a skew,

The reason you're seeing this is because you have lots and l

Jonas,
You can query the admin sockets of your monitors and osds get a json
listing of their running configuration. The command will look something
like:

# ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok config show

Hey all,
For those who have been following, or are interested in, the Ceph User
Committee [0] discussed at CDS [1] there is now a mailing list to
discuss all things User Committee. This could include:
* Proposed changes to Ceph.com
* Event participation and coverage
* Community development logis
Suppose I should have mentioned, as with the other mailing lists you
can find the info to subscribe at:

A little info about wip-port.
The wip-port branch lags behind master a bit, usually a week or two
depending on what I've got going on. There are testers for OSX and
FreeBSD, and bringing in windows patches would probably be a nice
staging place for them, as I suspect the areas of change will overl
