The Ceph Manager daemon (ceph-mgr) runs alongside monitor daemons, to
provide additional monitoring and interfaces to external monitoring and
management systems.
Only works as of the Kraken release.

Until now, only the first task were executed.
The idea here is to use `listen` statement to be able to notify multiple
handler and regroup all of them in `./handlers/main.yml` as notifying an
included handler task is not possible.

Problem: too many different commands to do the same thing. The 'cut'
command on infrastructure-playbooks/purge-cluster.yml was also wrong.
This sed command from osixia in ceph-docker

That could be a problem if the time synchronization is managed by

If a group of hosts is empty, (for instance 'mdss', in case of a
deployment without any mds node), the playbook will fails when trying
to restart service with `"'dict object' has no attribute u'XXX'"` error.
The idea here is to force the `with_items` statements in all included handler tasks
to get at least an empty array.

systctl tuning should be in the sysctl.d directory. This creates

This fixes issue #1299. According to @ktdreyer s comment in the ticket,
he fixed the web server config so also older (non-SNI) python clients
can use the uri module here.
This removes the implicit order requirement when using OSD fragments.
When you use OSD fragments and ceph-osd role is not the last one,
the fragments get removed from ceph.conf by ceph-common.
It is not nice to have this code at two locations, but this is
necessary to prevent problems, when ceph-osd is the last role as
ceph-common gets executed before ceph-osd.
This could be prevented when ceph-common would be explicitly called
at the end of the playbook.

Prior to this change, ceph-ansible would install the main NFS Ganesha
server daemon on Ubuntu, but it would skip the Ceph FSALs.
Running "apt-get install nfs-ganesha" will only install the main NFS Ganesha
server. It does *not* pull in the RGW FSAL
(/usr/lib/x86_64-linux-gnu/ganesha/libfsalrgw.so)
Running "apt-get install nfs-ganesha-fsal" will install the RGW FSAL as
well as the main NFS Ganesha server package.

From Josh Durgin, "I'd recommend not setting vfs_cache_pressure in
ceph-ansible. The syncfs issue is still there, and has caused real
problems in the past, whereas there hasn't been good data showing lower
vfs_cache_pressure is very helpful - the only cases I'm aware of have
shown it makes little difference to performance."

As of Infernalis, the Ceph daemons run as an unprivileged "ceph" UID,
and this is by design.
Commit f19b765 altered the default
civetweb port from 80 to 8080 with a comment in the commit log about
"until this gets solved"
Remove the comment about permissions on Infernalis, because this is
always going to be the case on the Ceph versions we support, and it
is just confusing.
If users want to expose civetweb to s3 clients using privileged TCP
ports, they can redirect traffic with iptables, or use a reverse proxy
application like HAproxy.

This gives us more flexibility than installing the ceph-release package

We changed the way we declare image.
Prior to this patch we must have a "user/image:tag"
format, which is incompatible with non docker-hub registry where you
usually don't have a "user". On the docker hub a "user" is also
identified as a namespace, so for Ceph the user was "ceph".
Variables have been simplified with only:
* ceph_docker_image
* ceph_docker_image_tag
1. For docker hub images: ceph_docker_name: "ceph/daemon" will give
you the 'daemon' image of the 'ceph' user.
2. For non docker hub images: ceph_docker_name: "daemon" will simply
give you the "daemon" image.
Infrastructure playbooks have been modified as well.
The file group_vars/all.docker.yml.sample has been removed as well.
It is hard to maintain since we have to generate it manually. If
you want to configure specific variables for a specific daemon simply
edit group_vars/$DAEMON.yml

Some users purge their environments and leave it in a non-optimal state.
e.g: packages are still installed but /etc/ceph and /var/lib/ceph don't
exist anymore. This will result in multiple failures across the play,
sometimes hard to detect. Populating these directories "just in case"
should help us solving these problems.

This allows the user to set ip_version to either ipv4 or ipv6. This

Allow for more operator flexibility in the `rgw frontends` setting
while maintaining backwards compatibility with the old vars. This
allows an operator to, for example, use the civetweb settings for
implementing SSL ports.

The libcephfs1 package was removed from ceph-common in
cb1c06901e, however it was not synced
to group_vars/all.yml.sample using the `generate_group_vars_sample.sh`
script. This fixes up the comment formatting in the ceph-common
defaults and brings the group_vars sample back into sync.
Prior to this change, a playbook run with '--tags' or '--skip-tags'
would fail, because the ceph-common role would not include the
release.yml task, and this file defines critical things like
ceph_release.
Thanks Andrew Schoen <aschoen@redhat.com> for help with the fix.
There is no need to become root on local_action. This will event trigger
an error on some systems as it will try to run a sudo command. If the
current user does not have passwordless sudo, Ansible will fail. Anyway
using the current user is perfectly fine and no elevation privilege is
needed.

The Keystone v2 APIs are deprecated and scheduled to be removed in
Q release of Openstack. This adds support for configuring RGW to
use the current Keystone v3 API.
The PKI keys are used to decrypt the Keystone revocation list when
PKI tokens are used. When UUID or Fernet token providers are used in
Keystone, PKI certs may not exist, so we now accommodate this scenario
by allowing the operator to disable the PKI tasks.
Jewel added support for user/pass authentication with Keystone,
allowing deployers to disable Keystone admin token as required
for production deployments.
This implements configuration for the new RGW Keystone user/pass
authentication feature added in Jewel.
See docs here: http://docs.ceph.com/docs/master/radosgw/keystone/
Just for clarity and because we can we now show the name of the

For some providers (such as upcoming Linode support), some NICs may have
multiple IP addresses. (In the case of Linode, the only NIC has a public
and private IP address.) This is normally okay as we can use the
ceph.conf cluster_network and public_network variables to force the
monitor to listen on the addresses we want. However, we also need
ansible to set the correct monitor IP addresses in "mon hosts" (i.e. the
addresses the monitors will listen on!). This new monitor_address_block
setting tells ansible which IP address to use for each monitor.
