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:

Hello Jan
I faced similar kind of errors and these are really annoying. I tried this and
worked for me.

2. check monitor logs from ceph-node1 on /var/lib/ceph directory. This will
give you more strength.
3. You might need
hi ceph,

I think this is a fine configuration - you won't be writing to the root
partition too much, outside journals. We also put journals on the same
SSDs as root partitions (not that we're very ambitious about
performance...).
Do you suggest a RAID1

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

ems is a remote machine?
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 All,
I found 6 pgs incomplete while ceph health detail after 3 osds down,

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
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
Hi Nathan,
Here is a very rough draft of the announcement which is going to be released
next monday. It is more a discussion starter than a draft. Feel free to modify
at will :-) It includes the names and affiliations of all founding members.
There may be more in the days to come and I'll add
We are investigating a curious problem with radosgw:
We see intermittent timeouts and http connections breaking when streaming video
files through the rados gateway.
On server 1 we have Ubuntu 13.10 (saucy) with the stock Apache 2.4 and
associated fastcgi (and a mon)
On server 2 we also have
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,
issues a warning. If you look at 'ceph health detail' you will see some of
the detail there.
The reason you're seeing this is because you have lots and
ceph pg 4.7d query
will tell you which OSDs it wants to talk to in order to make the PG
complete (or what other information it needs).

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

Is there any way to make the creation process better? We are hoping to be

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
