It is - no longer dependent on Apache in order to run. The MAAS Region - controller is now controlled by ``maas-regiond`` upstart job or systemd - unit. The ``maas-regiond`` daemon is available in port ``5240``. - - **Firewall ports for Region and Cluster controller communication** - The communication between Region and Cluster controller is now limited - to use the ports between ``5250`` and ``5259``. For all of those users who - are using a remote cluster (not running on the same machine as the - MAAS Region Controller), need to ensure that these ports are open in - the firewall. + **New Networking Concepts and API's: Fabrics, Spaces and Subnets** + With the introduction of new MAAS networking concepts, new API's are also + been introduced. These are: + + * fabrics + * spaces + * subnets + * vlans + * fan-networks + + MAAS 1.9.0 will continue to provide backwards compatibility with the old + network API for reading purposes, but moving forward, users are required to + use the new API to manipulate fabrics, spaces and subnets. + + **Advanced Network and Storage Configuration only available for Ubuntu deployments** + Users can now perform advanced network and storage configurations for nodes + before deployment. The advanced configuration is only available for Ubuntu + deployments. All other deployments using third party OS', including CentOS, + RHEL, Windows and Custom Images, won't result in such configuration. + + **Re-commissioning required for upgraded MAAS** + Now that storage partitioning and advanced configuration is supported natively, + VM nodes in MAAS need to be re-commissioned. + + * If upgrading from MAAS 1.8, only VM nodes with VirtIO storage devices need + to be re-commissioned. + + * If upgrading from MAAS 1.7, all nodes will need to be re-commissioned in + order for MAAS to correctly capture the storage and networking devices. + + This does not affect nodes that are currently deployed. + + **Default Storage Partitioning Layout - Flat** + With the introduction of custom storage, MAAS has also introduced the concept + of partitioning layouts. Partitioning layouts allow the user to quickly + auto-configure the disk partitioning scheme after first commissioning or + re-commissioning (if selected to do so). The partitioning layouts are set + globally on the `Settings` page. + + The current default Partitioning layout is 'Flat', maintaining backwards + compatibility with previous MAAS releases. This means MAAS will take the + first disk it finds in the system and use it as the root and boot disk. + + **Deployment with configured /etc/network/interfaces** + Starting with MAAS 1.9, all node deployments will result in writing + `/etc/network/interfaces` statically, by default. This increases MAAS' + robustness and reliability as users no longer have to depend on DHCP for + IP address allocation solely. + + MAAS will continue to provide IP addresses via DHCP, even though interfaces + in `/etc/network/interfaces` may have been configured statically. Major new features ------------------ - **Web UI Re-design** - MAAS now includes a newly re-designed Web UI. The new Web UI features - a new design and a lot of usability improvements. Some of the UI new - features include: - - * Live Updating - The new UI now allows users to view the current status of the - various nodes of MAAS in real-time and without having to manually - refresh the browser. - - * Bulk Actions - Quickly select multiple nodes or devices and perform actions. If - nodes or devices are not in a state where that action can be - performed MAAS will alert you to the machines allowing you to - modify your selection before performing the action. - - * Live Searching - View the matching nodes or devices as you search. Just type and the - nodes will start to filter, no reloading or waiting for the page to - load. - - * Better Filtering - Easily filter through the list of nodes and devices in MAAS to find - the specific nodes that match your search. Examples: - - * All nodes that are Ready and have at least 2 disks:: - status:Ready disks:2 - - * All nodes that are not Ready:: - status:!Ready - - * All nodes that have Failed to complete an action:: - status:Failed - - * All nodes that are deployed but their power is off:: - status:Deployed power:off - - * Node & Storage Tag Management - Administrators can now add and remove tags for both Machine and - Storage. This is now possible via the Web UI from the `Node Details` - page. - - * Add Chassis - A new `Add Chassis` feature has been added to the UI. This is an - option of `Add Hardware`. This not only allows administrators to - add machines that belong to a single chassis, but also allows - administrators to add Virtual Machines for both KVM and VMWare - based products. - - **Support for Devices** - MAAS adds a new concept for a different type of machines, called - `Devices`. `Devices` are machines that MAAS does not fully manage; - this means that MAAS can not power manage nor properly control. - `Devices` are machines in the Network that MAAS can provide network - services for (DHCP/DNS), or can track for inventory. - - Administrators can assign three different types of IP Address to a - device: - - * `External`, which can be any IP address on the network. - * `Static`, which can be selected manually or automatically, and - belongs to Subnetwork that MAAS can control. - * `Dynamic`, any IP address that is automatically assigned by MAAS - via DHCP. MAAS will automatically create a DNS mapping for any of - the IP addresses belonging to a Device. - - **Storage Discovery** - Storage that is attached to a node in MAAS is now a first class - citizen. Easily view and filter nodes based on the number of disks - and the size of each disk attached to a node. Information retrieved - from a storage device includes its name, model, serial, size, - block size, and extra information that is applied to a storage device - as a tag. MAAS will auto tag devices including tags for solid state - device (ssd), rotary, rpm speed, and connected bus. - - **Twisted Daemons** - The MAAS Region Controller no longer requires an Apache frontend. It - is still used by default to be backward compatible, but the MAAS - Region Controller is now a standalone Twisted process (the twisted - daemon for the Cluster Controller, ``maas-clusterd``, was introduced - in MAAS 1.7). The MAAS Region Controller is now ``maas-regiond``. - - Starting from MAAS 1.8 the Region Controller and Cluster Controller - are noq controlled only by two daemons. (``maas-regiond`` and - ``maas-clusterd`` respectively) - - **DB Isolation** - Previously PostgreSQL was used in the default READ COMMITTED - transaction isolation mode. It has now been increased to - REPEATABLE READ. PostgreSQL thus provides extra support to ensure - that changes in MAAS are logically consistent, a valuable aid in a - busy distributed system. - - **VMware support** - VMware products are now supported in MAAS. This allows MAAS to register - all the Virtual Machines that the VMWare product is running (or a subset - whose name matches a specified prefix), set them up to PXE boot, and - configure them for power management. - - This feature requires the ``python-pyvmomi`` package to be installed. - (This is a suggested package, so be sure to use ``--install-suggests`` on - your ``apt-get`` command line when installing the MAAS cluster, or install - it manually.) - - The following VMware products have been tested: vSphere Hypervisor 5.5, - ESXi 5.5, and Workstation 11. This feature supports both i386 and amd64 - virtual machines. + **Storage Partitioning and Advanced Configuration** + MAAS now supports Storage Partitioning and Advanced Configuration natively. + This allows MAAS to deploy machines with different Storage Layouts, as + well as different complex partitioning configurations. Storage support + includes: + + * LVM + * Bcache + * Software RAID levels 0, 1, 5, 6, 10. + * Advanced partitioning + + Storace configuration is available both via the WebUI and API. For more + information refer to :ref:`storage`. + + **Advanced Networking (Fabrics, Spaces, Subnetworks) and Node Network Configuration** + MAAS now supports Advanced Network configuration, allowing users to not + only perform advanced node network configuration, but also allowing users + to declare and map their infrastructure in the form of Fabrics, VLANs, + Spaces and Subnets. + + **Fabrics, Spaces, Subnets and Fan networks** + MAAS now supports the concept of Fabrics, Spaces, Subnets and FANS, + which introduce a whole new way of declaring and mapping your network + and infrastructure in MAAS. + + The MAAS WebUI allows users to view all the declared Fabrics, Spaces, + VLANs inside fabrics and Subnets inside Spaces. The WebUI does not yet + support the ability to create new of these, but the API does. + + These new concepts replace the old `Network` concepts from MAAS' + earlier versions. For more information, see :ref:`networking`. + + For more information about the API, see :ref:`api`. + + **Advanced Node Networking Configuration** + MAAS can now perform the Node's networking configuration. Doing so, + results in `/etc/network/interfaces` being written. Advanced + configuration includes: + + * Assign subnets, fabrics, and IP to interfaces. + * Create VLAN interfaces. + * Create bond interfaces. + * Change interface names. + + MAAS also allows configuration of node interfaces in different modes: + + * Auto Assign - Node interface will be configured statically + and MAAS will auto assign an IP address. + * DHCP - The node interface will be configured to DHCP. + * Static - The user will be able to specify what IP address the + interface will obtain, while MAAS will configure it statically. + * Unconfigured - MAAS will leave the interface with LINK UP. + + **Curtin & cloud-init status updates** + Starting from MAAS 1.9.0, curtin and cloud-init will now send messages + to MAAS providing information regarding various of the actions being + taken. This information will be displayed in MAAS in the `Node Event Log`. + + Note that this information is only available when using MAAS 1.9.0 and + the latest version fo curtin. For cloud-init messages this information + is only available when deploying Wily+. + + **Fabric and subnet creation** + MAAS now auto-creates multiple fabrics per physical interface connected + to the Cluster Controller, and will correctly create subnetworks under + each fabric, as well as VLAN's, if any of the Cluster Controller + interface is a VLAN interface. + + **HWE Kernels** + MAAS now has a different approach to deploying Hardware Enablement + Kernels. Start from MAAS 1.9, the HWE kernels are no longer coupled + to subarchitectures of a machine. For each Ubuntu release, users + will be able to select any of the available HWE kernels for such + release, as well as set the minimum kernel the machine will be + deployed with by default. + + For more information, see :ref:`hardware-enablement-kernels`. + + **CentOS images can be imported automatically** + CentOS Image (CentOS 6 and 7) can now be imported automatically from the + MAAS Images page. These images are currently part of the daily streams. + + In order to test this images, you need to use the daily image stream. + This can be changed in the `Settings` page under `Boot Images` to + `http://maas.ubuntu.com/images/ephemeral-v2/daily/`. Once changed, images + can be imported from the MAAS Images page. The CentOS image will be + published in the Releases stream shortly. + Minor notable changes --------------------- - **RPC Communication & Ports** - RPC communication between the Region Controller and the - Cluster Controller has now been limited to use the ports between 5250 - and 5259, inclusive. - - **Discovered virtual machine names are imported into MAAS** - When using the new `Add Chassis` functionality (or the - ``probe_and_enlist`` API), virtual machines (VMs) imported into MAAS will - now use the names defined within the Hypervisor as hostnames in MAAS. - This feature works with KVM (virsh or PowerKVM) and VMWare VMs. - - The names of the virtual machines will be converted into valid - hostnames, if possible. For example, if a VM called `Ubuntu 64-bit` - is imported, it will become `ubuntu-64-bit`. - - Note that only the hostname portion of the name is used. For example, - if a VM is called `maas1.example.com`, only the “mass1” portion of the - name will be used as the node name. (The cluster configuration - determines the remainder of the DNS name.) - - **Virtual machine boot order is now set automatically** - When using the new `Add Chassis` functionality (or the - `probe_and_enlist` API) to add KVM or VMware virtual machines, MAAS - will automatically attempt to set each virtual machine’s boot order so - that the network cards (PXE) are attempted first. (This increases the - repeatability of VM deployments, because a VM whose boot order is - incorrectly set may work *once*, but subsequently fail to deploy.) - - **Systemd Support** - MAAS now supports systemd, allowing all of the MAAS daemons to run - with Systemd, if the Ubuntu system is running systemd by default - instead Upstart. These daemons include ``maas-regiond``, - ``maas-clusterd``, ``maas-dhcpd``, ``maas-dhcpd6``, ``maas-proxy``. - - **Upstart & Systemd improvements** - Both Upstart Jobs and Systemd Units now run and supervise various - instances of the ``maas-regiond`` in order to be able to effectively - handle all requests. - - Known Problems & Workarounds - ---------------------------- - - **Disk space is not reclaimed when MAAS boot images are superseded** - Whenever new boot images are synced to ``maas-regiond``, new large - objects in the database are created for them, which may replace older - versions of the same image (for the specified version/architecture - combination). Unfortunately, the standard postgresql `autovacuum` - does not remove large objects that are no longer used; a - “full vacuum” is required for this. Therefore, a new command has - been introduced which will run the appropriate postgresql vacuum - command (See bug `1459876`_):: - - maas-region-admin db_vacuum_lobjects - - This command should be run with care (ideally, during a scheduled - maintenance period), since it could take a long time (on the order - of minutes) if there are a large number of superseded images. - - .. _1459876: - https://launchpad.net/bugs/1459876 - - **MAAS logs to maas.log.1 instead of maas.log** - The `/var/log/maas/maas.log` is a rsyslog based log file, that gets - rotated in the form of `maas.log.1`, `maas.log.2.gz`, etc. In one - situation it has been seen that `maas.log` is empty, and rsyslog - was sending logs to `maas.log.1` instead. This has been identified - as an issue in rsyslog rather than maas. See bug `1460678`_. - - .. _1460678: - https://launchpad.net/bugs/1460678 + + **Minimal Config Files for Daemons** + Starting from MAAS 1.9, minimal configuration files have been introduced + for both, the MAAS Region Controller and the MAAS Cluster Controller daemons. + + * The Region Controller (`maas-regiond`) has now dropped the usage of + `/etc/maas/maas_local_settings.py` in favor of `/etc/maas/regiond.conf`. + Available configuration options are now `database_host`, `database_name`, + `database_user`, `database_pass`, `maas_url`. MAAS will attempt to migrate + any configuration on upgrade, otherwise it will use sane defaults. + + * The Cluster Controller (`maas-clusterd`) has now dropped the usage of + `/etc/maas/pserv.yaml` and `/etc/maas/maas_cluster.conf` in favor of + `/etc/maas/clusterd.conf`. Available configuration options are now `maas_url` + and `cluster_uuid` only. MAAS will attempt to migrate any configuration + on upgrade, otherwise it will use sane defaults. + + **Commissioning Actions** + MAAS now supports commissioning actions. These allow the user to specify + how commissioning should behave in certain escenarios. The commissioning + actions available are: + + * Enable SSH during commissioning & Keep machine ON after commissioning + * Keep network configuration after commissioning + * Keep storage configuration after commissioning + + **Warn users about missing power control tools** + MAAS now warns users about the missing power control tools. Each MAAS + power driver use a set of power tools that may or may not be installed + by default. If these power tools are missing from the system, MAAS will + warn users. + + **Python Power Drivers** + Starting from MAAS 1.9, MAAS is moving away from using shell scripts + templates for Power Drivers. These are being migrated to MAAS' + internal control as power drivers. Currently supported are APC, MSCM, + MSFT OCS, SM15k, UCSM, Virsh, VMWare and IPMI. + + Remaining Power Drivers include AMT, Fence CDU's, Moonshot.

MAAS 1.9 has proven to be more robust, and higher deployment rates without failures than 1.9.0. This lab is a high load lab that stress tests deployments with MAAS. 2. Every MAAS release is thoroughly tested for upgrades. For 1.9, upgrade tests include: - Upgrading from 1.5 to 1.9 directly - Upgrading from 1.5 to 1.7 to 1.8 to 1.9 - Upgrading from 1.7 to 1.9 3. MAAS CI Lab: - Tests Installation (from pkgs), configuration / customization of MAAS, enlistment, commissioning. It also tests deployments with Juju. - Tests various API's - Tests are performed against Trusty. 4. Other manual testing include: - Installation (both fresh and upgrades) - Configuration - Taking nodes through the lifecycle for regression testing. - Custom configuration to ensure proper operation. - Tests API's for regressions, and keeping backwards compatibility. 5. Landscape has thoroughly tested 1.9 before moving away from 1.7, not only to ensure backwards compatibility but also to test new features and capabilities. ========= Changelog ========= 1.9.0 ===== Important announcements ----------------------- **New Networking Concepts and API's: Fabrics, Spaces and Subnets** - With the introduction of new MAAS networking concepts, new API's are also - been introduced. These are: - - * fabrics - * spaces - * subnets - * vlans - * fan-networks - - MAAS 1.9.0 will continue to provide backwards compatibility with the old - network API for reading purposes, but moving forward, users are required to - use the new API to manipulate fabrics, spaces and subnets. + With the introduction of new MAAS networking concepts, new API's are also + been introduced.
