I have DSM 6.2.3-25426 update 3. I have problems with disk chrashes all the time. Every few days volume 1 (here I run docker and cointainers) crashes, ther is no bad sectors, disk is ok. After restart DSM everything is ok. But after few days disk crashes agian. I tried with 3 new disk, happens again on every of them where is docker installed. So disk is not faulty. Tried different DSM image - again disk crashes.
What can be wrong ?
