Getting the following errors in Fix Common Problems

Unable to write to cache

Unable to write to Docker Image

 

My array is far from empty : 

15.3 TB used of 26 TB (59.0 %)

 

My cache drives look like this :

 

59.1 GB used of 1 TB (5.9 %)

 

All drives show health on SMART

 

I included the diag file from my array.

 

Can anyone help me out i'm not very good with linux systems

 

Regards

Your cache pool has issues (which I'm not going to help with as I'm nowhere near knowledgeable on btrfs pools), which is resulting in the docker.img file being mounted read-only

Pool is corrupt, you should backup, re-format and restore data 

Will try it.
