OS6 now works on x86 Legacy WARNING: NO NTGR SUPPORT!

I have readyNAS 2100v2 and managed to install OS 6.0.8. First thanks to the forum who helped me in installing and making the readynas to run on the latest OS :)

I have managed to make Fan Control to work as well for ReadyNAS 2100v2.
/etc/fancontrol details:

I have also managed with the temperature monitoring using this forum help:

NOW I am struggling with the Volume entries listing correctly under System->Volumes.
I have four HDD, two 2TB HDD and two 1TB HDD, but the display only shows first two disk i.e. two 2TB HDD, other two 1TB HDD is not shown in the UI.
