Hi,
I've been trying to tweak and improve the performance of our ceph cluster.
One of the operations that I can't seem to be able to improve much is the
delete. From what I've gathered every time there is a delete it goes
directly to the HDD, hitting its performance - the op may be recorded in

That's also why you generally want to limit RAID5 arrays to maybe 6

After dealing with ubuntu for a few days I decided to circle back to centos 7.
It appears that the latest ceph deploy takes care of the initial issues I had.
Now i'm hitting a new issue that has to do with an improperly defined url.
When I do ceph-deploy install node1 node2 node3 it fails
Found the file. You need to edit /usr/lib/python2.7/site-
packages/ceph_deploy/hosts/centos/install.py line 31 change to return 'rhel'

Probably a bug that needs to be fixed in the deploy packages.

When I attempt to use the ceph-deploy install command on one of my nodes I

Hi ceph team. I encoutered a problem like bug#8641. ( It's bigger than his.)
Then the eviction doesn't work. So I want to know the logic of evicting data or
where is the code of controlling the eviction.
The following text is my configuration.
max_bytes is 1G;
max_objects is 1M.
Hello everyone:
Since there's no cuttlefish package for 14.04 server on ceph
repository (only ceph-deploy there), I tried to build cuttlefish from
source on 14.04.
Here's what I did:
Get source by following http://ceph.com/docs/master/install/clone-source/
Enter the sourcecode directory
git
Actually, we haven't had any CentOS7 builds, that is why there is no
`el7` in the repos. We are in the middle of getting that sorted out.
Sorry you had to find this!
Also, keep in mind that there is no need really to edit those files.
You can tell ceph-deploy what URL to use and force it with:
Running into an issue w/ Cuttlefish where an RBD snap removal (from
OpenStack Glance) crashed my MON. I was able to get the MON back up and

Hi there,
I am using CentOS 7 with Ceph version 0.80.5

also serves as ceph-deploy node)
I followed all the instructions in the docs, regarding setting up a basic
Ceph cluster, and then followed the one to setup RadosGW.

There have been a ton of updates to Kraken over the past few months. Feel free

Just as easy to setup before, with a lot more functionality. OSD+MON+AUTH
operations are coming in the next release.

It just hasn't been implemented yet. The developers are mostly working on
big features, and waiting to do these small optimizations later. I'm sure
there are plans to address this, but I doubt it will be soon.
If you're interested, you're welcome to contribute:
Hi,
I have installed created a single node/single osd cluster with latest master
for some experiment and saw it is creating only rbd pool by default not the
data/metadata pools. Is this something changed recently ?
