Upgrade Notes

If you created any zpools using 6.12.0-beta5 please erase those pools and recreate them.

If you revert back from 6.12 to 6.11.5 or earlier, you have to force update all your Docker containers and start them manually after downgrading. This is necessary because of the underlying change to cgroup v2 in 6.12.0-rc1.

Upon boot, VM Autostart is prevented if all PCI devices specified in the 'config/vfio-pci.cfg' file do not properly bind. However, you may still start individual VMs. This is to prevent Unraid host crashes if hardware PCI IDs change because of a kernel update or physical hardware change. To restore VM autostart, examine '/var/log/vfio-pci-error' and remove offending PCI IDs from 'config/vfio-pci.cfg' file and reboot.

Linux Multi-Gen LRU is a relatively new feature now included but not enabled by default. You can enable by adding this line to your 'config/go' file:

 echo y > /sys/kernel/mm/lru_gen/enabled

If you revert back from 6.12 to 6.11.5 or earlier you may need to remove that line.
