The Unraid 6.12.7-rc1/rc2 releases contain bug fixes and security updates that we'd like feedback on before releasing 6.12.7. If you installed rc1, please upgrade to rc2 as it fixes problems related to installing license keys.
Upgrade steps for this release
- As always, prior to upgrading, create a backup of your USB flash device: "Main/Flash/Flash Device Settings" - click "Flash Backup".
- Update all of your plugins. This is critical for the Connect, NVIDIA and Realtek plugins in particular.
If the system is currently running 6.12.0 - 6.12.6, we're going to suggest that you stop the array at this point. If it gets stuck on "Retry unmounting shares", open a web terminal and type:
The array should now stop successfully (this release takes another stab at preventing issues related to Docker not stopping properly)
If you have the Connect plugin installed and updated to the latest version
- Open the dropdown in the top-right of the Unraid webgui and click Check for Update. More details in this blog post
If you don't have the Connect plugin installed
- Go to Tools -> Update OS and switch to the "Next" branch. If the update doesn't show, click "Check for Updates"
- Wait for the update to download and install
- If you have any plugins that install 3rd party drivers (NVIDIA, Realtek, etc), wait for the notification that the new version of the driver has been downloaded.
This thread is perfect for quick questions or comments, but if you suspect there will be back and forth for your specific issue, please start a new topic. Be sure to include your diagnostics.zip.
This release has two very important fixes. First, we updated Docker to incorporate fixes for their recent security advisory.
Second, we fixed a corner case bug which can lead to data loss if a newly added array drive has a non-standard partition layout. If you add one of these drives, the second time you start the array the drive will show as unformatted. If this happens please contact support and we can help you with data recovery. Even if you have not encountered this issue, we recommend upgrading so that you will not be affected when adding drives in the future.
This release also includes some nice fixes in networking, Docker containers, Time Machine support, and VMs as well as fix for a slowdown some systems were having on the Dashboard. We have also improved the SMART attribute handling for NVME and SSD drives. Details below.
Out of date plugins
Out of date plugins can cause problems, we recommend they be kept current.
Call traces and crashes related to macvlan
If you are getting call traces related to macvlan (or any unexplained crashes, really), as a first step we recommend navigating to Settings > Docker, switching to advanced view, and changing the Docker custom network type from macvlan to ipvlan. This is the default configuration that Unraid has shipped with since version 6.11.5 and should work for most systems.
Note that some users have reported issues with port forwarding from certain routers (Fritzbox) and reduced functionality with advanced network management tools (Ubiquity) when in ipvlan mode. If this affects you, see the alternate solution available since Unraid 6.12.4.
Network problems due to jumbo frames
If you are having network issues of any kind, confirm that you have not enabled jumbo frames. Navigate to Settings > Network Settings > eth0 and confirm the Desired MTU is 1500. For more information see the Fix Common Problems warning for jumbo frames.
Problems due to Realtek network cards
Upgraded kernel fixes the deadlock issue with jumbo frames and the in-tree Realtek 8125 driver. However, we still recommend following the advice above regarding jumbo frames.
If you continue to have network stability issues and Tools > System Devices shows that you have a Realtek ethernet controller, grab the part number shown and search Community Apps to see if there is a Realtek vendor-supplied driver plugin for that device. For more information, see the support page for Realtek driver plugins.
We highly recommend installing the Fix Common Problems plugin as it will warn you of common configuration problems.
If you are having other crashes or stability issues, navigate to Settings > Syslog Server and enable Mirror syslog to flash. This will cause additional wear and tear on you USB flash boot device but is useful in the short term for gathering logs after a crash.
Finally, start a new topic and provide all the details of the issue. Once the issue is resolved, be sure to disable Mirror syslog to flash.
Be aware that rolling back to an earlier release will make your system vulnerable to the Docker security issues and potential data loss scenario mentioned in Upgrade notes.
If rolling back earlier than 6.12.6, also see the 6.12.6 release notes.
Changes vs. 6.12.6

- Use "lazy unmount" unmount of docker image to prevent blocking array stop
- Updated to address multiple security issues (CVE-2024-21626, CVE-2024-24557)
- Boot faster by checking for carrier before assigning DHCP addresses
- Remove leading zeros from IPv4 and IPv6 addresses
