Thanks for you reply
Why a 80Go docker.img? Because when this problem occurs the first time, I was thinking it came from this docker size, and I set it from 20 to 80 Go.
What I have already done, without success:
- 20G to 80G docker 😆
- Bios update
- Change SATA cable for cache drive
- Change SATA port for cache drive
- Empty, remove cache drive + cache pool, reformat with default unraid format
- SMART test on cache drive
I will try the FAQ about Ryzen based server, without conviction as it was running for more than 1.5 years without problem.
