yesterday both cache disks disapperead and are now only shown as "Historical Devices" the cache setting does not say "missing". Here is what I have done before:
Connected a new drive via case usb port
Ran two preclear cycles
Stopped the array; increased array slots by one and selected the new diskt
Then the dropdown menu for the first of my two cache ssd's became blank and I could not select anything
Unraid listed the disk as "Historcal Device"; fdisk -l did not show the disk anymore;
I rebooted the server
Now both cache drives are "Historical" and not selectable nor recognized by fdisk.
I tried removing the newly added disk from the parity but it did not help
What would be my next step? Could the motherboard have a limit on how many drives it can detect? Any pointers are appreciated.
Here are some specs
