openstack/devstack-plugin-ceph - devstack-plugin-ceph - OpenDev: Free Software Needs Free Tools

Currently the devstack ceph plugin uses installation,
configuration, startup, and shutdown commands that do not always
work correctly for Ceph releases after hammer or with systemd
init system.
Check the ceph version and the init system and use appropriate
commands.

In a lab setting it can be useful to allow multiple manila devstacks,
each with its own CephFS filesystem, to share a common REMOTE_CEPH
cluster.
Parameterize the name of the CephFS filesystem that devstack creates
and enable creation of multiple filesystems if appropriate variables
are set in local.conf.
Note that since separate filesystems require separate data and metadata
pools, one also needs to set values for the extant CEPHFS_DATA_POOL and
CEPHFS_METADATA_POOL parameters.

Although the devstack ceph plugin uses variables - CEPHFS_DATA_POOL and
CEPHFS_METADATA_POOL - as arguments to the 'osd pool create' commands
that provision the pools required for manila to use the CephFS Native
backend, the overrides to the default values for these variables sets
both of them to $CEPHFS_CEPH_POOL. This setting is counter-intuitive,
and worse, forces use of a single pool for both data and metadata in the
case both default values are overridden.
Use CEPHFS_DATA_POOL and CEPHFS_METADATA_POOL as the override
variables for the data pool and metadata pool, respectively.

The CEPH_DATA_DIR variable holds the location of Ceph drives and
objects. It defaults to '/var/lib/ceph'.
Replace hardcoded occurrences of '/var/lib/ceph' with
'${CEPH_DATA_DIR}'.

Restacking with ceph plugin fails when trying to install
the cinder user's ceph authorization key in libvirt's list
of secrets because there is already a secret in that list
with the same uuid. The function _undefine_virsh_secret
is run on cleanup and should have removed that key from
the libvirt secret list.
Fix a typo in the variable name for the uuid that identifies
the authorization key in the secret list so that the
cleanup routine removes the key as intended.

The rule_id line is formatted as:
 "rule_id": 0,
Which means the id integer is the second column of the parsed output,
not the third.
Since a third column doesn't exist, the call to cut returns nothing,
leaving $RULE_ID invalid, which then causes the subsequent ruleset
commands to fail.
We don't see this normally because $CEPH_REPLICAS is set to 1 by
default.

In commit bb773e7285 the key for
verifying release packages from ceph.com was removed when support for
the ceph package mirrors was added. However, it is still needed for
non-gate case of fetching packages from ceph.com, so this adds it
back in that case.

For the ceph job to be voting, infra requires that we pull packages from
a pre-configured repository that's mirrored and reliable for gate jobs.
They have arranged for ceph.com packages to be mirrored and will store a
link to those packages in /etc/apt/sources.list.d/ceph.list. If this
file is present, we should use it. If not, then we're free to update
the sources list to fetch the latest packages.
This approach is required to regain voting status in the gate.

The changes in Ceph that were needed to make manila's cephfs_native
driver work are available in the Jewel branch. It's no longer
necessary to use the 'wip-manila' branch.
Also, with Jewel branch, manila's libcephfs client needs to be root
to perform certain manila operations. So set manila's client as root.

If we want to put the disk image into a tmpfs, changing CEPH_DATA_DIR
won't work because some file operation needed by ceph are not allowed
on tmpfs.
So, this change allows to change the disk image path only instead of the
whole CEPH_DATA_DIR.

So if the directory exists the stack does not fail.

Since we're about to be voting and I expect a few more people to be
interested in the code, I think now is the best time to fix the
indenting. It's a large patch, but there should be no functional
changes.
I removed one unused function and renamed internal-only function to be
prefixed with '_'.

This was renamed from drivers.cephfs to
drivers.cephfs.cephfs_native at the
request of the Manila maintainers.

Currently glance v2 doesn't allow to specify custom
locations for image by default, it returns 403.
To enable this 'show_multiple_locations' param must
be set to True.
When Nova is doing snapshots with Ceph it provides
location to activate image, which fails when we use
Glance v2.
To fix it we change the default param to True.
'show_image_direct_url' will be overridden.

Use ceph.conf to set the default pool replica size, thus
avoiding the need to set replica size for each pool

This patch enables the plugin to setup ceph radosgw and configures
it as a swift-compatible endpoint with keystone integration.
ENABLE_CEPH_RGW is the new variable introduced, which is False
by default, and can be set to True in localrc if radosgw needs
to be setup.
Fixed couple of other (related) things ...
1) Created rgw specific functions
2) Checking for radosgw & swift co-existence, erroring out early enough
NOTE: Tested on ubuntu trusty only
TODOs ...
1) Not tested on Fedora (F22), radosgw startup has some issues there.

The cleanup_ceph_embedded function nukes the ceph
conf directories, so when subsequently trying
to stop services they aren't stopped. Next stack.sh
run will fail because daemons are still running.
Fix by stopping daemons before running cleanup.

When Manila is to be configured with CephFS backend, explicitly
install `ceph-mds` package. The newer versions of Ceph packages,
do not have the dependency between `ceph` and `ceph-mds` packages.

Let the plugin setup and configure CephFS as the storage backend for
Manila. This is not done by default. Refer the README to do so.
Add 'pre_test_hook' and 'post_test_hook' scripts that would be needed
to configure Manila-Ceph CI jobs.
The following changes are also made:
* Install a development version of Ceph that is compatible with Manila's
 CephFSNative driver.
* The development version is a version greater than Infernalis. And
 from Infernalis onwards, the ceph daemons are run as user "ceph".
 So allow the daemons to run as user "ceph" for such versions.
* Enhance get_ceph_version to check Ceph version even when the
 ceph mon daemon is not up, by checking the CLI version.

Add configurables so that one need not have Ceph be the storage
backend for Cinder, Cinder-backup, Glance and Nova.
Let Ceph be the default storage backend for Cinder, Cinder backup,
Glance, and Nova. Allow the default setting to be overriden when the
global config, ENABLE_CEPH_{CINDER,C_BAK,GLANCE,NOVA} is set to
False in the local.conf/localrc file.
