What do you mean by this? With cache=yes any new files written to that share will go to cache.

You should read the help built into the GUI for the Use Cache setting.    That will point out that it is the Prefer setting that gives the behaviour you want.

i did sir. 
 

Use cache pool (for new files/directories): Yes = Mover transfers files from cache to array

But it did still move some files back from Array to Cache. 
--------------------------------------------------------------------------------------------------------

This morning did i stop all data going into unraid and did start the mover. IT did move the files from cache to array

When it was done the array was at 1 tb used 

afther thath i did start all the data input again 

but when i did check the main again. The array was like 600 gb Used and the cache was back to 700 Gb used 

so as i see it did the array move like 400 gb back to the cache 

You are likely to get better informed feedback if you attach your system’s diagnostics zip file to your next post in this thread as that will let us see how all your shares are set up and where they files for them are currently located.

Did you change the setting to Prefer?    That is the only setting that causes files to transfer from array to cache.    It is worth noting that you may also need to temporarily disable the Docker and VM services under Settings to get files related to these services moved to the cache as mover will not move any files that are currently open.

i did start at Prefer this morning. i did misunderstand it and dident read the help note 
When i did notic it need to be yes insted of prefer i did only stop all my docker not disable it 

i will try to disable docker now let it move all files and then test again

parity sync still running 
Is this a problem for the cache ?

System and domains are on cache, and that is fine, data is mostly on disk1, but like mentioned any new data written to that share goes initially to cache, that is expected behavior.

i do have like 2 Cache systems 

 

1 x Nvme for docker and system 

 

2x 500 GB in raid1 for Data

 

Docker and VMs folders are on the cache pool, only appdata is on the NVMe pool.

It's still a problem 

 

did try to remake it all.. i thinck there is a BUG or something with the cahce 

Atm Cahce is useless 

i do have 1 TB cache but even if my drive is put to Yes (Mover transfers files from cache to array)

it still moves files from arry to cache. This is i a huge problem when the array is 16 tb and the cache is 1 tb

When do you see that? That's not possible with cache="yes", but like mentioned any new data written to that share will go to cache.

im using NZBGET and Qbit to get files 
 

Whe way i see it is

when i start it all my array is on like 4.01TB 
Cache start at 25 gb 

afther 30 min 

my cache is on like 250 GB used 
but my array is gone down to like 3.8 TB

i if thoes 2oo GB isent grone form array to cache were did they so go :I in the perfeckt world sud my cache start to fill up. the mover kick in and my array will only go up  Right?

When the cace is put to yes?

Like mentioned it's not possible for Unraid to move data form array to cache with cache=yes, something else is going on, possible with how you have the containers configured.
