VM Manager Improvements 

Added support for VM clones, snapshots, and evdev passthru.

The VM editor now has a new read-only inline XML mode for advanced users, making it clear how the GUI choices affect the underlying XML used by the VM.

Big thanks to @SimonF for his ongoing enhancements to VMs.

Unraid Array Now Optional

You can now set the number of unRAID array slots to 'none'. This will allow the array to Start without any devices assigned to the unRAID array itself.

If you are running an all-SSD/NMVe server, we recommend assigning all devices to one or more ZFS/BTRFS pools, since Trim/Discard is not supported with unRAID array devices.

To remove the unRAID array from an existing server, first unassign all Array slots on the Main page, and then set the Slots to 'none'.

For new installs, the default number of slots to reserve for the unRAID array is now 'none'.

Share secondary storage may be assigned to a pool​

Shares can now be configured with pools for both primary and secondary storage, and mover will move files between those pools.

Can use 'mover' to empty an array disk​

Mover can now be used to empty an array disk. With the array started, run this at a web terminal:

mover start -e diskN |& logger &  # where N is [1..28]

Mover will look at each top-level director (share) and then move files one-by-one to other disks in the array, following the usual config settings (include/exclude, split-level, alloc method). Move targets are restricted to just the unRAID array.

Watch the syslog for status. When the mover process ends, the syslog will show a list of files which could not be moved:

• maybe file was in-use
• maybe file is at the top-level of /mnt/diskN
• maybe we ran out of space

Since ReiserFS is scheduled to be removed from the Linux kernel, the option to format a device with ReiserFS has also been disabled. You may use this mover function to empty an array disk prior to reformatting with another file system. We will add a webGUI button for this in a future release.

Predefined Shares Handling​

The Unraid OS Docker Manager is configured by default to use certain predefined shares:

• system - used to store Docker image layers in a loopback image stored in system/docker.
• appdata - used by Docker applications to store application data.

The Unraid OS VM Manager is configured by default to use certain predefined shares:

• system - used to store libvirt loopback image stored in system/libvirt
• domains - used to store VM vdisk images
• isos - used to store ISO boot images

When either Docker or VMs are enabled, the required predefined shares are created if necessary according to these rules:

• if a pool named 'cache' is present, predefined shares are created with 'cache' as the Primary storage with no Secondary storage.
• if no pool named 'cache' is present, the predefined shares are created with the first alphabetically present pool as Primary with no Secondary storage.
• if no pools are present, the predefined shares are created on the unRAID array as Primary with no Secondary storage.

Networking​

• Resolved issue starting Docker containers on custom IPv6 networks
• Auto-generate network.cfg at boot if one does not exist
• Added support for NFS 4.1 and 4.2
• Permit NFSv4 mounts by default
• Upgraded to OpenSSL 3
• Allow ALL IPv4/IPv6 addresses as listener. This solves the issue when IPv4 or IPv6 addresses change dynamically
• Samba:
  • Add ipv6 listening address only when netbios is disabled
  • Fix MacOS unable to write 'flash' share and restore Time Machine compatibility (fruit changes)
• The VPN manager now adds all interfaces to WireGuard tunnels, make a dummy change to the tunnel after upgrading or changing network settings to update WireGuard tunnel configs.

webGUI​

Integrated Dynamix File Manager plugin​

Click the file manager icon and navigate through your directory structure. You can perform common operations such as copying, moving, deleting, and renaming files and directories.

Integrated GUI Search plugin​

Click the search icon on the Menu bar and type the name of the setting you are looking for.

Outgoing Proxy Manager​

If you previously used the Proxy Editor plugin or had an outgoing proxy setup for CA, those will automatically be removed/imported. You can then adjust them on Settings > Outgoing Proxy Manager.

For more details see the manual.

Note: this feature is completely unrelated to any reverse proxies you may be using.

Notification Agents​

Notification agents xml are now stored as individual xml files, making it easier to add notification agents via plugin.

See this sample plugin by @Squid

NTP Configuration​

For new installs, a single default NTP server is set to 'time.google.com'.

If your server is using our previous NTP defaults of time1.google.com, time2.google.com etc, you may notice some confusing NTP-related messages in your syslog. To avoid this, consider changing to our new defaults: navigate to Settings > Date & Time and configure NTP server 1 to be time.google.com, leaving all the others blank.

Of course, you are welcome to use any time servers you prefer, this is just to let you know that we have tweaked our defaults.

Dashboard​

• Add server date and time to dashboard, click the time to edit related settings
• Rework the System tile to clarify what is being shown, including tool tips
• Show useful content when dashboard tiles are minimized
• Fix browsers leaving dashboard visibility cookies in malformed state
• Reset dashboard tiles when switching language
• Show heat warnings for low temperatures too
• Some color adjustments

SMART improvements​

• Display KB/MB/GB/TB written in SMART Attributes for SSDs
• Add 'SSD endurance remaining' SMART Attribute.
• Fix display of 'Accumulated power on time, hours:minutes xxxxx:yy' SMART attribute
