Hi,

I cant figure out why my disks are keep getting utilised despite have a 8tb cache drive as the main primary source of storage. Whilst the downloader is running I am seeing file activity on a disk in the array, its very low writes but i don't think my drives should be touched, especially with docker running on its own ssd.

I am using the trashguides <Data file structure with usenet as a subdirectory for downloads inside. I have uploaded some screenshots plus the diagnostic data

Once files have been moved to the array then obviously when they're accessed that will be from the array drive they're on.

I moved over 7tb last night and now I am starting it up with a empty cache drive. If im not moving at the same time as downloading then why is this action happening for a file that has just finished now. Why does disk 2 need to be utilised when the file will be on the cache drive saznbd is the client and is moving it to completed category for arr client to pick it up.

You say you moved last night, your data share is set to be moved to your array so all of its contents are now on the array, since incomplete downloads are also in the data share that'll include them.

Thanks for your quick reply. Should i turn off secondary storage until I am ready to move files to the array then, is that a solution?

If you want incompletes to always be on cache then the solution would be to have another share for those that is set to only reside on cache.

Thanks, so if i create a share for incompletes that is cache drive only then this will only store the data on the cache drive. Once the file has been completed then this will go back into the completed folder in (DATA USENET) then the same result would happen again with the array be written to? I am assuming this hard linking automation cant avoid writes to the array unless i do everything manually correct (moving files myself?) from one share to another.

Once my my large queue is completed then i won't have so much of a problem and my disks hopefully can start to spin down.

It would be moved from the incomplete share to the data share, since the data share is primary cache then that will remain on cache, and only go to array when the mover runs.

Hardlinks wouldn't work indeed.

I believe most people solve this by running the mover infrequently, or by using the mover tuning plugin set to only move files that are older than a few days/weeks or based on cache fill state. When it works that is, that plugin often has issues these days

So just to clarify the following should work if i change Saznbd directories.

Saznbd will place incomplete download in a separate share

Saznbd will move the download from incomplete share to completed folder in the main Data share

Arr will pick up that there is a completed download and then move this to the appropriate directory such as 'Tv Shows' / Movies for example.

Run mover overnight will move the files into the array

The end result should mean that the array will only be touched when either the cache drive fills or mover is operating.

Thanks for your help again.
