hey, i just installed an nvme in order to use it for jellyfin (docker), 

 

it's set as a pool device, only now that i try to format it, it's telling me it will update parity

thanks @bmartino1!

 

im still a bit confused though, i don't remember cache drives being part of parity (also mentioned in the docs, https://docs.unraid.net/legacy/FAQ/cache-disk/#overview)

 

i know pools are different in Unraid 7, just not sure how to move forward

 

also, i dont remember this happening when i added a cache drive  on a 6.x system a while back

 

maybe the dialog isn't picking up that i want to format a cache drive, not an array drive ?

 

the wording "Create an empty file system on the disks shown as Unmountable discarding all data currently on the disks and update parity to reflect this" is what makes me doubt

I belive that just unriads normal warning message with new new disk and formatting.

The disk drive is new new.

and as you have a array disk setup its apart from the normal warning as the new new disk needs to be formatted first. Thus, the warning.

The parity and disk will do what you tell it to do.

I think your ok to proceed. Just note that in the normal disk array setup that the cahce disk pool is uses sometimes to assisting the unriad with parity.

Pools are not part of parity, you can ignore the message, it's the same for array or pool format.

I think maybe the message that pops up needs a little rework?   The *Warning* paragraph should probably be the first one, and the other one reworded slightly to make it clear it only applies to drives that are part of an Unraid style parity protected array.  Any other changes needed?

Yeah, it should, I believe there's a feature request for that, but I'm not finding it.
