I am having a weird issue with my cache drive. I had one of my cache SSD drives mess up on me. It started to show errors that it was read only (which is understandable since the drive was one I knew was ify at best (OCZ refurbished if that tells you anything). I wanted some protection about 2 weeks ago so I was going to add another ssd along with some bigger drives. I installed the bigger drives and let them finish with the pre-clear and the parity fix. I installed the new drive and let it do a balance and that seemed to store the data on the new SSD. I have since removed the defective drive from the cache and have another ordered but my cache "should be" operational. In the mean time the cache devices show that I have 468GB of data (the OCZ was 256GB and the Kingston was 240GB). I only have one drive shouldn't it show 240GB? Do I have to run a special command to get it to correct itself?

 

I also am having another issue with the appdata. I have the fix common problems plugin (fantastic for noobs to unraid btw).  It is telling me that the appdata needs to be cache only for my docker images. I have gone to my shares and specified it be cache only. I have run the mover. I have rebooted and still I am getting the same message when I run the check. I have disabled the VM (which I am not using currently) and docker. Am I missing something simple here?

Oh and one more thing I can't seem to stop the array while the cache is enabled for some reason. It started when I added the other cache drive and removed the existing.

To move files from array to cache you need Use Cache=Prefer.   A value of Only means new files are created on the cache but it does not move existing files.  This should be clearer if you enable the GUI help for that field.  

Thanks for the help. I have set them to Prefer before and then ran mover and it didn't move them over. 

 

I also was looking at the cache settings and ran a Scrub. It showed several unrecoverable sectors. I think it copied them from the bad drive. How can I reformat the cache partition and start fresh? I think that will fix the issue since it copied them from the defective drive. I don't really have anything on the cache drive that I need to save as I have just been playing around with the docker images. 

I actually found some documentation on the wiki that told me step by step how to do it. It seems to be working now. Recreating the docker images as we speak.
