I think i know the answer.

 

I was upgrading my single cache drive last night. 500gb to 1 tb. I installed the new drive. It took me a while but this was the process that i did.

 

Created a new pool called newcache. Added it to the cache pool making cachenew the primary and cache the secondary and preferring to have the files on newcache. Ran the mover and waited a lifetime. Checked cache and it was almost empty. Ran the mover again and the drive was completely empty. I removed the cache from the pool and started the array dockers etc. 

 

I thought i was good but after starting everting it is like a brand new dockers with all my appdata being lost. I was able to recover some stuff. Some of my servers were not auto start and those appear to be ok.

 

What did i do wrong? Any way I missed something and can recover my appdata?  I have had such good luck i took the risk of moving without a backup.  

Did you change the name back to cache? If you were using any /mnt/cache path, they won't work with /mnt/newcache

No i did not realize i needed to change the name. I thankfully think i have my kids minecraft worlds. I didnt have them autostart and think that might he saving grace. Everything else is a pain in the ass but i can get through it. 

 

I still see the approximate same amount of usage. Is there any chance the files are hidden and recoverable.

If you use /mnt/user, you don't need to change anything, but if the docker/VM settings, or some containers themselves, were using /mnt/cache, then you would need to change the pool name or the paths.

I looked through the dockers and renaming doesn't resoning doesnt make sense to me. But I am a complete novice. Here is my node red example /mnt/user/appdata/nodered/. The change I made.

Thank everyone for there help. I posed this question in hopes to have some answers after work. I was able to recover a good portion of the dockers and some were not affected. I had to update 1 docker that referenced cache.

 

I tried to rename the cache to cache but that made it worse. So I changed it back to cachenew.

 

I thought about a few things today and discovered this afternoon.

While i was cleaning up i deleted 2 users. I thought it was unrelated at the time but you never know. I believe i created them a long time ago when i was attempting to try and use the nas as a game drive at some point and pretty sure they were remnants of that. 

I also have a user and user0? Why is this?  With a single appdata in it and a nodered folder.

 

I would like to mention that if the mover was working i think i would have avoided all of this. The mover would not move my files from cache back to the array. I also could not find good directions for moving these files around manually

 

I also made a cardinal sin and made changes without backing up anything. I should have been more diligent . This is not worth the heart ache. Thanks again for any guidance

user is the user shares, user0 is only those files on the array.

None of your user shares are configured to be moved.
