Hi,
fio is probably the tool you are looking that supports both RBD images and
other disk devices for testing so that you can bench your Ceph cluster as week
as compare it with other devices.
Cheers

Hello,
Currently I am integrating my ceph cluster into Openstack by using Ceph’s RBD.
I’d like to store my KVM virtual machines on pools that I have made on the ceph
cluster.
I would like to achieve to have multiple storage solutions for multiple
tenants. Currently when I launch an instance the

You need to increase the 'ulimit -n' max open files limit. You can do
this in ceph.conf with 'max open files' if it's sysvinit or manually in
/etc/init/ceph-osd.con
Can you please open a ticket in at tracker.ceph.com with this backtrace,
and some info about what workload and system config led to this? Are you
using erasure coding and/or tiering?
Thanks!

I'm trying to follow the idea to enable COW with cinder, but it seems like

Could someone please explain me how to apply the patch appropriately?

Hey All,
Thanks for the quick responses! I have chosen the micron pci-e card due to
its benchmark results on
http://www.storagereview.com/micron_realssd_p320h_enterprise_pcie_review .
Per the vendor the card has
a 25PB life expectancy so I'm not terribly worried about it failing on me
too soon :)
Excellent choice.. we did put 2 of them (350G) in Dell R720xd with
24x 10K 1.2Gb drives... Excellent performance.. we now need to test
it on low latency switches .. (we are on regular switches 2x10GB per
servers).
I know for that amount of OSD we would need 3 cards to max out IO but

FWIW you can run centos 6 with 3.10 kernel from elrepo.

Yehuda,
what do you mean by the rewrite rule? is this for Apache? I've used the ceph
documentation to create it. My rule is:
RewriteRule ^/([a-zA-Z0-9-_.]*)([/]?.*)
/s3gw.fcgi?page=$1¶ms=$2&%{QUERY_STRING}
[E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
Or are you talking about something
What version of Ceph are you using? mkcephfs was deprecated with the
Cuttlefish release. You can still see the old documentation for mkcephfs
here: http://ceph.com/docs/cuttlefish/start/. However, most people use
ceph-deploy to bootstrap a cluster now.
The output looks like exactly half of the obj
