Hi All,

 

Does anyone know how to migrate your settings from an old install of UNRAID(v6.2.4) to a fresh UNRAID(v6.3.5) install? In particular I would like to at least migrate the disk, user and shares setup; if possible migrating the plugins and VM would be great as well but those I can setup again.

I have tried copying the config folder over but non of my shares show up and I cannot add a new share. Disks, Users, VMs and plugins seem to be recognised fine. I then tried again without plugins and without the shares.cfg but still the same thing but this time my disk setup was not loaded(I know the specific slots though so got that setup and I can browse to the folders through "Main" tab). Diagnostics attached from this attempt.

 

FYI as a background I am doing this because my last install of UNRAID(v6.2.4) has been acting odd and probably corrupted slightly. There was a botched upgrade(kernel panic) to v6.3.4 via the plugins tab and I had to revert by copying the "previous" folder syslinux and bzroot etc files. Powerdown buttons no longer work with 404 error and I have to manually stop the array and powerdown in order to shut it down, reboot does not work either. The entire system hangs when a VM gets stuck as well and the webgui will be unavailable.

Download the 6.3.5 zip file from limetech's website, and overwrite all of the bz* files contained within it onto the flash drive.  (Maybe make a backup of the existing files first)

Thanks that seemed to have worked. Shares, users and VMs all showing up and I can access the shares fine.

 

However for some reason my VM which used to start no longer does. I get the following error:

I remember seeing at one point where people were suggesting PCIe ACS override to fix this or some override option I can't find again. PCIe ACS override doesn't seem to be the issue as when reading up on it, its more for when your devices are not in separate IOMMU groups but mine are. Any idea what may be wrong?

I found the problem, I needed to add

"allow_unsafe_assigned_interrupts=1"

 after append in

Quote

 append initrd=/bzroot

in the syslinux.cfg which is accessible by clicking on "Flash" under the Main tab

 

Forgot that it used to be there and it got nuked when reseting the USB. For future reference though, is there no GUI option for this?
