We identified an issue with mdadm version "mdadm - v4.4 - 2024-11-07 - 4" that can cause software RAID issues after a reboot. We have removed this version and pushed a downgraded version "mdadm - v4.4 - 2024-11-07 - 2" to the Security Onion repo.
If you are not running software RAID, then you should not be affected at all.
If you are running software RAID, then you should check to see what version of the mdadm package is installed on all of your grid members to see if they need to be downgraded.
Please note that the following instructions assume that you installed using our official Security Onion ISO image. If you are using some other unsupported installation method, then your mileage may vary.
Check the existing mdadm version on all grid nodes:
sudo salt \* cmd.run 'mdadm --version'
If all grid nodes show version "mdadm - v4.4 - 2024-11-07 - 2", then you are running the correct version.
If one or more grid nodes have version "mdadm - v4.4 - 2024-11-07 - 4" then you need to downgrade mdadm:
sudo salt \* cmd.run 'echo y | dnf downgrade mdadm'
Once that completes, then verify the downgraded version on all nodes:
sudo salt \* cmd.run 'mdadm --version'
