I am new to Ceph and am looking at trying to utilize some existing hardware
to perform 2 tasks per node. We have a 2 servers which can hold 12 & 16
drives and probably 4 servers which take 4 drives.
Ideally, if possible, we would like to install XCP on each of these servers,
and use Ceph to clust

I’ve been watching with great eagerness at the design and features of ceph

Hi all,
We're about to go live with some qemu rate limiting to RBD, and I wanted
to crosscheck our values with this list, in case someone can chime in with

The only reasonable, non test-suite, values I found on the web are:

I'm confused...
The bug tracker says this was resolved ten days ago. Also, I actually used
ceph-deploy on 2/12/2014 to add two monitors to my cluster, and it worked, and
the documentation says it can be done. However, I believe that I added the new

Hi,
We experience something similar with our Openstack Swift setup.
You can change the sysstl "vm.vfs_cache_pressure" to make sure more inodes are
being kept in cache.

Good spot!!!
The same problem here!!!
