Thanks for all your answers,
Today people dedicate servers to act as ceph osd nodes which serve data stored inside to other dedicated servers which run applications or VMs, can we think about squashing the 2 inside 1?

This is fairly standard for container deployment: one app per container instance. This is how we're deploying docker in our upstream ceph-docker / ceph-ansible as well.

Hi,
Just wonder why you want each OSD inside separate LXC container? Just to
pin them to specific cpus?

Hi,
I am currently defining a storage architecture based on ceph, and i
wish to know if i don't misunderstood some stuffs.
So, i plan to deploy for each HDD of each servers as much as OSD as
free harddrive, each OSD will be inside a LXC container.
Then, i wish to turn the server itself as a rbd client for objects
created in the pools, i wish also to have a SSD to activate caching
(and also store osd logs as well)
The idea behind is to create CRUSH rules which will maintain a set
of object within a couple of servers connected to the same pair of
switch in order to have the best proximity between where i store the
object and where i use them (i don't bother having a very high
insurance to not loose data if my whole rack powerdown)
Am i already on the wrong track ? Is there a way to guaranty
proximity of data with ceph whitout making twisted configuration as
i am ready to do ?
Thks in advance,
Regards
