MAAS provisions bare-metal or virtual servers on a reachable network segment.
Machine List
The machine list in MAAS is a central dashboard displaying servers with details like status, power state, owner, and tags. Hovering over status icons reveals additional information, such as warnings for failed hardware tests. The Add hardware menu enables adding new machines or chassis. Selecting machines activates the Take action menu for various operations. Filtering options allow refining the machine list based on attributes and keywords.
CLI Dashboard
A non-interactive machine dashboard can be generated via the CLI with jq:
maas admin machines read | jq -r '(["FQDN","POWER","STATUS", "OWNER", "TAGS", "POOL", "NOTE", "ZONE"] | (., map(length*"-"))),
(.[] | [.hostname, .power_state, .status_name, .owner // "-", .tag_names[0] // "-", .pool.name, .description // "-", .zone.name]) | @tsv' | column -t
This output provides an overview of each machine’s state, tags, and assignment.
Machine Summary
Selecting a machine’s FQDN or MAC address (in the UI) opens a summary view with key details:
- Overview: Status, OS version, and owner.
- CPU & Memory: Specs and test links.
- Storage: Disk layout and modification options.
- Domain & Zone: Configuration settings with edit links.
- Power Type: Configurable power settings.
- Tags: Assigned tags with edit options.
Most machine events are accessible from the Machines menu.
USB & PCI Devices
Machines may include USB or PCI devices such as keyboards, GPUs, or network cards. These devices are detected during commissioning and listed under the PCI devices and USB tabs, showing device type, vendor ID, product ID, driver name, NUMA node (if applicable), and address.
These devices can be removed via the CLI:
maas $PROFILE node-device delete $SYSTEM_ID $DEVICE_ID
Recommissioning the machine will restore detected devices.
Network Configuration
The Network tab allows viewing and editing machine network settings. Changes can be made while a machine is in the ‘Ready’ state.
Booting & Power Management
The Booting tab provides machine configuration options, including PXE boot settings.
- Hard Power-Off immediately shuts down power.
- Soft Power-Off (MAAS 3.5+) gracefully shuts down the OS.
Storage Management
MAAS supports various storage configurations, including:
- Traditional partitioning, LVM, RAID, and bcache.
- UEFI boot mechanisms.
- Storage configuration for CentOS and RHEL, including RAID and custom partitioning (ZFS and bcache excluded).
Storage layouts are applied during commissioning, and users can modify configurations as needed. Multiple disk erasure options are available when releasing a machine.
