Good evening,

 

after filling my NAS server with data for the first time at par before I had put turbo write and disable cache now I can not reactivate them I have however 3 SSDs so 2 NVMe and 1 SATA I show you with JPG

 

thank you in advance for the answers

Please post the diagnostics 

I could be wrong but do you have a cache pool set up?

It seems to me that your ssd's are used as unassigned devices and not assigned to a dedicated cache pool in the array.

I had created a pool but my server crashed after disabling the cache

Both NVMe devices are part of a btrfs pool, just assign them together to a new or existing empty pool.

Thank you for this information,

 

if you could give me the procedure to follow because it's been a week that I search in the English forum and French even on redit, and since I am starting on a raid I am afraid to break everything

 

thank you very much

You already have a pool called 'cache', stop array, assign both NVMe devices to that pool, start array.

thank you very much
