Cache Only share (folders) start appearing on the array

[sdfyjert]

I have a cache only share (`/mnt/user/tmp`). Lately fix common problems has found a bit troublesome too often that the cache-only tmp share is appearing on the array disks. This is not new, I have seen it in the past but it was way too rare like once a year. Now all of the sudden it starts becoming once a week issue.

 

Some facts

• The settings of that share are set for over 2 years now. Actually all my shares have not been modified (settings wise) for over 2 years.
• The last two times it happened the folders found on the array are cache-only folders mounted to dockers running sonarr and radarr.
  • Sonarr (move files)
  • Radarr (move files)
• The last two times it happened, I find only empty folders on the array drive (that belong to the cache-only share).

 

How can I help you help me?

And how likely is it that I have some underlying bigger issue? Should I worry about my data?
