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. 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. 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 Major bugs fixed in this release -------------------------------- See https://launchpad.net/maas/+milestone/1.8.0 for full details. #1185455 Not obvious how to search nodes along a specific axis, or multiple axes #1277545 Node list sort order not maintained #1300122 No way to get the version of the MAAS server through the API #1315072 Finding BMC IP address requires clicking "Edit node" in Web UI #1329267 CLI does not tell users to issue a "refresh" when the API gets out of date #1337874 Re-commissioning doesn't detect NIC changes #1352923 MAAS 1.8 requires arbitrary high-numbered port connections between cluster and region controllers #1384334 Dnssec failures cause nodes to be unable to resolve external addresses #1402100 Nodes can be in Ready state without commissioning data, if you mark a node in 'failed commisioning', broken and then fixed. #1412342 Maas.log only contains cluster logs #1424080 Deployment Failed -- Failed to get installation results #1432828 MAAS needs to write power off jobs to to systemd units instead of upstart #1433622 Maas cluster name should not / can not have trailing '.' #1433625 'APIErrorsMiddleware' object has no attribute 'RETRY_AFTER_SERVICE_UNAVAILABLE' #1435767 Retry mechanism fails with oauth-authenticated requests #1436027 Interfaces does not have entry for eth0 #1437388 exceptions.AttributeError: 'NoneType' object has no attribute 'is_superuser' #1437426 No view for loading page or notification for connection error #1438218 django.db.transaction.TransactionManagementError: raised when deploying multiple nodes in the UI #1438606 Releasing node not transitioned to "Failed releasing" #1438808 Network and storage tables on node details page mis-aligned in Firefox #1438842 Cannot add an extra NIC #1439064 Title of individual commissioning result page is permanently "Loading..." #1439159 maas packaging in vivid needs to prevent isc-dhcpd and squid3 from running #1439239 MAAS API node details failures #1439322 Simultaneous IP address requests with only one succeeding #1439339 "Choose power type" dropdown broken in FF #1439359 When upgrading to MAAS 1.7 from MAAS 1.5, MAAS should trigger the image import automatically. #1439366 MAAS 1.7 should be backwards compatible with 1.5 the preseed naming convention #1440090 NIC information (networks / PXE interface) get's lost due to re-discovering NIC's during commissioning #1440763 Rregiond.log Tracebacks when trying to deploy 42 nodes at a time #1440765 oauth.oauth.OAuthError: Parameter not found: %s' % parameter #1441002 Maas api "device claim-sticky-ip-address" fails with "500: 'bool' object has not attribute 'uuid'". #1441021 No IP validation #1441399 Socket.error: [Errno 92] Protocol not available #1441610 Machines get stuck in releasing for a long time #1441652 502 Proxy Error when trying to access MAAS in browser #1441756 Manager service is not sending limit to region #1441841 Can't add a device that has IP address that it is within the wider range MAAS manages, but not within Dynamic/Static range MAAS manages #1441933 Internal Server Error when saving a cluster without Router IP #1442059 Failed deployment/release timeout #1442162 Spurious test failure: maasserver.api.tests.test_nodes.TestFilteredNodesListFromRequest.test_node_list_with_ids_orders_by_id #1443344 MAAS node details page shows BMC password in cleartext #1443346 utils.fs.atomic_write does not preserve file ownership #1443709 Error on request (58) node.check_power #1443917 IntegrityError: duplicate key value violates unique constraint "maasserver_componenterror_component_key", (component)=(clusters) already exists #1445950 Proxy error when trying to delete a windows image #1445959 Deploying a different OS from node details page yields in always deploying ubuntu #1445994 Add Devices button has disappeared #1445997 Clicking on a device takes be back to node details page #1446000 MAC is not shown in device list #1446810 Too Many Open Files in maas.log #1446840 Internal server error saving the clusters interfaces #1447009 Combo loader crash when requesting JS assets #1447208 deferToThread cannot wait for a thread in the same threadpool #1447736 Node isn't removed from the node listing when it becomes non-visible #1447739 Node isn't added to the node listing when it becomes visible #1449011 maas root node start distro_series=precise on a non- allocated node returns wrong error message #1449729 Nodes fail to commission #1450091 tgt does not auto-start on Vivid #1450115 django.db.utils.OperationalError raised when instantiating MAASAndNetworkForm #1450488 MAAS does not list all the tags #1451852 Legacy VMware "add chassis" option should be removed #1451857 Probe-and-enlist for VMware needs to update VM config to use PXE boot #1453730 Commissioning script contents is shown under other settings #1453954 500 error reported to juju when starting node -

(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.
