Hi.

I have 1 SSD NVME 2TB on cache.Since yesterday, I have been encountering problems, and when I checked the log, I saw this warning.

It won't let me copy or move files from the cache to the RAID disks. But, for example, if I create a folder called “test” and move it, I have no problem. I tried creating a 1 GB file and had no problem either.

But, for example, I tried to copy the docker.img and couldn't.

Btrfs is detecting data corruption, recommend running memtest.

I ran a test and got an error. I replaced all the modules with others I had at home, and so far, I haven't gotten any more errors.

Thank you!
