How many cache devices did you have? unRAID is expecting 3:

 

Jul 13 10:28:40 Hydra emhttpd: cache uuid: 2a38254d-bd36-4b73-a53c-ed0246d5810c
Jul 13 10:28:40 Hydra emhttpd: cache TotDevices: 3
Jul 13 10:28:40 Hydra emhttpd: cache NumDevices: 1
Jul 13 10:28:40 Hydra emhttpd: cache NumFound: 1
Jul 13 10:28:40 Hydra emhttpd: cache NumMissing: 0
Jul 13 10:28:40 Hydra emhttpd: cache NumMisplaced: 2
Jul 13 10:28:40 Hydra emhttpd: cache NumExtra: 0
Jul 13 10:28:40 Hydra emhttpd: cache LuksState: 0
Jul 13 10:28:40 Hydra emhttpd: /mnt/cache mount error: Too many missing/misplaced devices

And were you using the default raid1 profile or did you change it?

I did have 3, and it appears 2 of them got directory corruption. I mounted 1 of the drives in a degraded state and am in process of copying the cache data over to the array and then I plan to rebuild the cache pool.

 

I think that seems to be the best course of action.

Exactly what I'm using. I got a bit panicked when I first saw what was going on and couldn't find anything with my initial search so I made this post. I then found your post, and am following now.

 

I'm at the step where my copy is done, and I'm getting ready to mount the cache pool again and copy back.

 

Thanks for your help.
