February 18, 20251 yr 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 i dont really want it to affect parity, what should i do ? also, i have a docker setup pointing to hard drives docker is it ok to just point it to the cache drive once working (ony one docker there which i can delete without issues)
February 19, 20251 yr Community Expert the cache disk is meant for the standard unraid array and is used as a cache disk (temp data) for parity writes, review the documentation: review: https://docs.unraid.net/legacy/FAQ/Parity/ https://docs.unraid.net/legacy/FAQ/cache-disk/
February 19, 20251 yr Author 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
February 19, 20251 yr Community Expert 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. review: 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. Edited February 19, 20251 yr by bmartino1 typo - Data
February 19, 20251 yr Community Expert Pools are not part of parity, you can ignore the message, it's the same for array or pool format.
February 19, 20251 yr Community Expert 1 hour ago, JorgeB said: 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?
February 19, 20251 yr Community Expert Yeah, it should, I believe there's a feature request for that, but I'm not finding it.
