I just noticed that one of my OSD's has its xfs filesystem created with
isize=256, instead of the 2048 it should have been created with.
Is this going to be hurting performance enough to warrant burning the OSD and
recreating it?
And is there a way to change it on the fly (I expect not, but may
Most of my OSD nodes are equipped with low voltage xeon (L5420) processors what
is probably somewhat of an overkill. For that reason I run them with other
services as well. However the board you are suggesting could be the answer for
less power consumption on the OSD nodes.
That still leaves me
Dear ceph users,
I just had a problem on a ceph cluster running three nodes with each:
- 24 cores
- 32Go RAM
- 2 SATA disks as OSD
- 2 SSD disks using software RAID for sys + journals
- libvirt+kvm
- ceph network use 2 dedicated Gigabit interfaces with active-passive to
two switches

our cluster seems to have recovered overnight and is back

You have to explicitly set public ACL on each object.

Hi all,
I am seeing some weirdness when trying to deploy Ceph Emperor on fedora 19
using ceph-deploy. Problem occurs when trying to install ceph-deploy, and seems
to point to the version of pushy in your repository:
[root@ceph02 ~]# yum install ceph-deploy
Loaded plugins: priorities, protectbas
Anybody using MONs and RGW inside docker containers?
I would like to use a server with two docker containers, one for mon
and one for RGW
This to archieve a better isolation between services and some reusable
components (the same container can be exported and used multiple times
on multiple server
I played with Docker for a while and ran into some issues (perhaps
from my own ignorance of Docker principles). The biggest issue seemed
to be that the IP was relatively ephemeral, which the MON really
doesn't like. I couldn't find a reliably intuitive way to have the
MON get either the same IP o
A long time ago I got my MDS cluster into a state where I have two active

I want to drop down to one active MDS node with two nodes for failover. Is
there any documentation for how to do this?
I tried the command "ceph mds

Hmm indeed, it changed my mds status from
e45538: 2/2/1 up {0=2=up:active,1=0=up:active}, 1 up:standby
to
e45541: 1/1/1 up {0=2=up:active}, 2 up:standby
Thank you very much!

Hi,
> The problem is: now I want to delete or rename the pool '-help',
maybe you will try using double-hyphen ("--") [1] , e.g. something (not tested)
like
ceph osd pool rename -- "-help" aaa
ceph osd pool delete -- -help

Hello to all,
I use heavily ceph-deploy and it works really well.
I've just one question : is there an option (i have not found) or a way to let
ceph-deploy osd create ...
create an OSD with a weight of 0 ?
My goal is to reweight step-by-step, after, news OSDs, to be sure that
it will not disturb
