[SOLVED] Cash drive unassigned after BIOS update

[adminmat]

After updating BIOS the 2nd Cache drive was unassigned. When I try to assign it I get the message  "All existing data on this device will be OVERWRITTEN when array is Started".  

 

I've tried Chrome, Firefox, disabling add blockers, booting in safe GUI mode and still get the same warning. Any idea why this happened? Should I just add it back and let it be Overwritten?

 

 

When selected in dropdown menu:

@JorgeB mind giving me a hand with this one?

Assuming you didn't already start the array with the single device do this:

 

If Docker/VM services are using the cache pool disable them, unassign all cache devices, start array to make Unraid "forget" current cache config, stop array, reassign all cache devices (there can't be an "All existing data on this device will be OVERWRITTEN when array is Started" warning for any cache device), re-enable Docker/VMs if needed, start array.

Thanks. No, I had not started the array with the single cache drive. Your instructions worked great. 

Here is what I just did with the array stopped (using Edge browser):

- Disabled VMs in VM Manager  (Docker service was already disabled before last shutdown)

- Set cache drive 1 to 'no device' using dropdown menu in Main tab (it then appeared in Unassigned Devices)

- Checked 'Yes' for "Start will remove the missing cache disk and then bring the array on-line."

- Clicked Start

- Array didn't start because it's now asking for Passphrase (it didn't ask before)

- Entered passphrase and clicked Start

- Stopped the array

- Reassigned both cache drives in proper order

- This time I don't see the "All existing data on this device will be OVERWRITTEN" message. There are blue squares next to each cache drive.

- Started array (both cache drives are mounted properly, no errors)

- Started Docker service

 

I tested Plex and Nextcloud and all is working well. Thanks for the advice.
