This patch adds the admin and user documentation for share revert to
the latest available snapshot.
Change-Id: Id35b99fdb47bb9de38f42034818fb4a29370bf36
Closes-Bug: #1657322
The driver inflated total and available capacity
due to an incorrect calculation. The driver was
also ignoring the configuration option
"reserved_share_percentage" that allows
deployers to set aside space from scheduling
to prevent oversubscription.
While this bugfix may have an upgrade impact,
some things must be clarified:
- Inflating the total, free space will allow
manila to schedule workloads that may run
out of space - this may cause end user
downtime and frustration, because shares are
created (empty subvolumes on ceph occupy no
space) easily, but they could get throttled
as they start to fill up.
- CephFS shares are always thinly provisioned
but, the driver does not support oversubscription
via manila. So, real free space is what
determines capacity based scheduler decisions.
Users however expect share sizes to be honored,
and manila will allow provisioning as long
as there is free space on the cluster. This
means that Ceph cluster administrators
must manage oversubscription outside of manila
to prevent misbehavior.

The CephFS driver optionally advertised snapshot
support to manila, based on a configuration
option "cephfs_enable_snapshots". Manila does not
provide snapshots by default to users, unless an
administrator chooses to set the "snapshot_support"
extra-spec in the share type they're using. So this
configuration option is really an unnecessary safeguard
at this point.
Moreover, CephFS snapshots are fully supported from
Ceph Nautilus, and with Id847b1b5e6623172f2600afd69e51182067444cb,
manila added a support statement for the Victoria
release that indicates that Nautilus is the minimum
version of ceph supported. So let's default this
option to True, and deprecate this option at the same
time to eliminate this duplicate safeguard.

The manila discussed cephfs futures
during the Victoria cycle PTG [1]. To support newer
features in ceph, we'll need to start using the
ceph-mgr interface that debuted in Nautilus.
When we start adopting ceph-mgr, we can no longer
support Mimic, Luminous and older releases of Ceph
without maintaining code workarounds and a continuous
integration system to ensure they're not broken.
This takes considerable effort from community members.
We've supported the Luminous release since OpenStack
Queens, and there have been at least
three other major releases of Ceph in the meantime,
let's add a release note and adjust the ceph driver
documentation calling out our support/testing stance.

Switch to openstackdocstheme 2.2.1 and reno 3.1.0 versions. Using
these versions will allow especially:
* Linking from HTML to PDF document
* Allow parallel building of documents
* Fix some rendering problems
Update Sphinx version as well.
Set openstackdocs_pdf_link to link to PDF file. Note that
the link to the published document only works on docs.openstack.org
where the PDF file is placed in the top-level html directory. The
site-preview places the PDF in a pdf directory.
Change pygments_style to 'native' since old theme version always used
'native' and the theme now respects the setting and using 'sphinx' can
lead to some strange rendering.
Remove docs requirements from lower-constraints, they are not needed
during install or test but only for docs building.
openstackdocstheme renames some variables, so follow the renames
before the next release removes them. A couple of variables are also
not needed anymore, remove them.

To set up some first party backends such as
ZFSOnLinux, CephFS via NFS gateway, Container
(where the NAS server is containerized) and LVM,
manila's devstack plugin creates a NAS server
on the devstack host.
On test machines, access to this NAS server is
firewalled from networks outside of the host's
internal network namespace (including from private
project networks that are in different network
namespaces, on the same devstack host).
We currently use a legacy devstack-gate script
to disable firewall on NFS ports; however,
anyone that installs devstack with LVM, Container,
ZFSOnLinux, CephFS-NFS drivers will need these
firewall ports to be opened to be able to mount
shares exported off their devstack host machines.
Move these firewall commands to the devstack plugin.
These commands can be invoked by setting the localrc
variable MANILA_ALLOW_NAS_SERVER_PORTS_ON_HOST to True.
The value of this variable is False by default,
to preserve existing behavior.
