Unraid 6.8 Now Available!

Unraid6 8 2

New For Unraid 6.8 Stable:

Forms Based Authentication

If you have set a root password for your server when accessing the Unraid webGUI you'll now see a nice login form. There is still only one user for Unraid so for username enter "root". This form should be compatible with all major password managers out there. As always, we highly recommend using a strong password. There is no auto-logout implemented yet, please click Logout on menu bar or completely close your browser to logout.

WireGuard® Support

Available as a plugin via Community Apps. Our WireGuard implementation and UI is still a work-in-process; for this reason we have made this available as a plugin, though the latest WireGuard module is included in our Linux kernel.

Note: WireGuard is a registered trademark of Jason A. Donenfeld.

Linux Kernel

We started 6.8 development and initial testing using the Linux 5.x kernel. However, there remains an issue when VM's and Docker containers using static IP addresses are both running on the same host network interface. This issue does not occur with the 4.19 kernel. We are still studying this issue and plan to address it via this release plan.

Changes to the kernel include:

  • Updated to 4.19.88
  • Includes the latest Intel microcode for yet another hardware vulnerability mitigation.
  • Default scheduler is now 'mq-deadline', but this can be changed via new Settings/Disk Settings/Scheduler setting.
  • Enabled Huge Page support, though no UI control yet.
  • binfmt_misc support.
  • Fixed chelsio missing firmware.
  • Added oot: Realtek r8125: version 9.002.02
  • Removed Highpoint r750 driver [does not work]

WS-Discovery Support

Finally, you can get rid of SMBv1 and get reliable Windows network discovery. This feature is configured on the Settings/SMB Settings page and enabled by default.

  • Also, on the same settings page is the Enable NetBIOS setting. This is enabled by default, however if you no longer have the need for NetBIOS discovery you can turn it off. When turned off, Samba is configured to accept only SMBv2 protocol and higher.
  • Added mDNS client support in Unraid OS. This means, for example, from an Unraid OS terminal session to ping another Unraid OS server on your network you can use (e.g., 'tower'):
    ping tower.local
    instead of
    ping tower
    Note: the latter will still work if you have NetBIOS enabled.

Update OS Tool

The Update OS tool still downloads the new release zip file to RAM but then extracts directly to the USB flash boot device. You will probably notice a slight difference in speed of extract messages. Also the 'sync' command at the end has been replaced with 'sync -f /boot' to prevent spin-up of all devices before the operation is considered complete.

User Share File System (shfs) changes:

  • Integrated FUSE-3 - This should increase the performance of the User Share File System.
  • Fixed a bug with hard link support. Previously a 'stat' on two directory entries referring to the same file would return different i-node numbers, thus making it look like two independent files. This has been fixed, however there is a config setting on Settings/Global Share Settings called "Tunable (support hard links)". The default is Yes, but with certain very old media and DVD players which access shares via NFS, you may need to set this to No.
  • Note: if you have custom config/extra.cfg file, get rid of any lines specifying additional FUSE options unless you know they are compatible with FUSE-3.

Other Improvements and Bug Fixes:

  • Fixed the SQLite DB Corruption bug.
  • Format - during Format, any running parity sync/check is automatically Paused and then resumes upon Format completion.
  • Encryption - an entered passphrase is not saved to any file.
  • Fixed a bug where multi-device btrfs pool was leaving metadata set to dup instead of raid1.
  • Fixed a bug where quotes were not handled properly in passwords.
  • Numerous base package updates including updating PHP to version 7.3.x, Samba to version 4.11.x.

To upgrade:

  • If you are running any 6.4 or later release, click 'Check for Updates' on the Tools/Update OS page.
  • If you are running a pre-6.4 release, click 'Check for Updates' on the Plugins page.
  • If the above doesn't work, navigate to Plugins/Install Plugin, select/copy/paste this plugin URL and click Install:
