Both Cache drives disappeared after adding new disk

[Lerrrtaste]

Hi,

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
 

Unraid Version: Version: 6.8.3
MB: ASRock H110M-DVS R3.0; American Megatrends Inc., Version P1.20
CPU: Intel Pentium G4560 @ 3.5RAM: 2* 4GB
Array: 1 Parity Disk; 6 Data Disks between 4 and 8 TB (including the new one)
Cache: 2* 240GB San Disk SSD Plus
Diagnostics: attached

Try different cables, you can then just check if they are detected in the board BIOS, if they aren't they also won't be detected by Unraid.

Thanks for looking into it, I will try new cables and report back.

I tried a different cable and then removed them from my server completely and tried connecting it to my PC with a SATA to USB adapter: Not showing up anyhwere...

 

Could they possibly died simulatinously? One of them is rather new.

 

No idea what else I could try

[JorgeB]

If they are not detected in different computer they are likely dead, not much else you can do.

Ok, thanks a lot for your help. To the backups it is then...
