After changing my cache pool disks from SATA to NVME I checked the Syslog file and there are a bunch of errors:

 

 

I found this thread:

 

There is a fix by editing the Syslinux configuration:

 

This is usually caused by a PCIe device, it can be fixed by moving the offending device to a different PCIe slot, updating the bios or adding pci=nommconfto your syslinux.cfg after append initrd=/bzroot, so it would look like:

 

append initrd=/bzroot pci=nommconfto

 

Can you please guide me to the right section where to add the fix? Thank you.

 

 

Should be under Unraid OS right?

Ok I found the final fix here and it´s working:

 

 

append initrd=/bzroot pci=nommconfto -> did not solve the problem for me.
