Big cluster will easily reach the default limit so we need to increase
it and make it configurable.

We remove all the partitions, label and re-create something clean prior
to prepare the design. This will help solving many issues with existing
disks or while scratching/deploy test environments often.

MDS and RGW are not deployed often (RGW more), so we disable them from
the default deployment to only get MONs and OSDs.

With the appropriate subscription details you will be able to use the
Inktank Ceph Enterprise version of Ceph running on RHEL7.

It has becomes really anoying to manually generate an fsid prior to the
inital bootstrap. This commit introduces a method that auto-generates an
fsid. If for whatever reasons you want to force your own fsid you can
simply edit these 3 files and override the fsid variable:
- roles/ceph-common/vars/main.yml
- roles/ceph-mon/vars/main.yml
- roles/ceph-osd/vars/main.yml

- We don’t need ceph-extra for trusty
- Enable multiverse repo for access to libapache2-mod-fastcgi
- Update cache before attempting to install packages to register
multiverse repo and only refresh cache once an hour to avoid delays in
the playbook
- Add wildcard to disabling default site as on Ubuntu it is 000_default
by…default
While running big boxes with 72 disks it's easy to get out of PID for
all the threads needed by Ceph. Increasing the default value removes
this limitation.

In ceph-common you load {{ ansible_managed }} at the top of the main
config file - this will trigger handlers on that file whenever an
Ansible run is made.
I'd suggest replacing it with a vanilla text comment 'managed by
Ansible' to warn
admins but avoid unnecessary cluster bounces.

The ceph.conf.j2 template currently always uses the current host facts
to get the IP address of each host in the mon loop. This is not the
expected behavior. This patch uses the correct facts to get the IP.
Recovery and/or re-balancing decrease performance, adding more options
might help tweaking this behavior.

Since 192.168.0.0/24 is very commong and might overlap with some
existing networks on your laptop, using another subnet like '42' is less
bound to happen.

Proviously we used osd_crush_update_on_start: true, this was interpreted
by Ansible as a boolean and appeared as 'True' inside the Ceph configuration
file. However the Ceph's init script is looking for 'true'.

This commits introduces the support of the developpement branches of
Ceph. You can now install Ceph from master.
The behavior is done through 2 new options:
* ceph_stable: true will use the stable branch
* ceph_dev: true will use the dev branch
For the dev packages don't forget to set the branch that you want to
use.

Prior to this patch, the first match was winning and the playbook wasn't
doing any difference both "restart ceph", adding a distro filtrer fixes
this.

It has been reported a couple of months ago by Dan van der Ster from
CERN that updatedb was consumming 100% of CPU while parsing system's
directories. Indeed the process was parsing the OSD PG directories that
might contains billions of objects.

After a change is made on the configuration file we must restart the
Ceph services. I also added a check that verifies if a socker exists
because during the first play there are no services running. We check if
a socket exists, if not we don't try to restart the services, if it
exists we can restart them.

I added a 'ceph-' prefix to all the roles related to Ceph. Since we are
about to push the roles into the Ansible Galaxy that will be easier when
we want to use these roles into a larger environement with other roles.

This commit implements a fourth scenario where we can directely use a
directory instead of a block device for the OSDs. The purpose of this
scenario is more testing-oriented. Please note that we do not check
the filesystem underneath the directory so it is really up to you to
configure this properly. Declaring more than one directory on the
same filesystem will confuse Ceph.

This commit introduces a new config option 'osd crush chooseleaf type'.
With the help of this option and by setting it to '0' we tell Ceph to
store all the replicas on a single host. Basically we tell CRUSH to
iterate over disk and not over host.

since we're now using fsid for the directory name, it should be safe to
just copy the keys from all mon hosts. Once they are copied, the rest of
the hosts will just skip copying. :)
