I figured that was going to be the answer. That is unfortunate. @Squid@trurl I appreciate you taking the time to try to help. Thank you.

I know. That was the risk I took.

I absolutely did not format every disk.

absolutely not, that is what unraid was for. 🙂 not trying to sound snarky....

@trurl that is what it did. the backup still exists on disk 13...Are you thinking I hit a bug or something?

What are your settings for the Appdata Backup/Restore. Screenshots of Appdata backup/restore attached. Did you change anything when you restored? Just what I mentioned previously about changing "Use cache (for new files/directories):" to "only" Did you ever run the Cleanup Appdata during this process? No I did not.

Almost always, the most important thing you need to do is capture your complete syslog, BEFORE YOU REBOOT! Yeah, I'm an idiot. I rebooted already. I know better. Is it a problem with a hard drive? No, this is absolutely an admin ignorance issue First, tell us the exact version of Unraid, the plugins and addons you have loaded, and what hardware you are using. Unraid Version: 6.8.2 M/B: MSI A88XM GAMING (MS-7903) Version 1.0 - s/n: To be filled by O.E.M. BIOS: American Megatrends Inc. Version V1.3.

I have docker running out of cache for plex/streaming purposes. I put the new drive in and restored a cache backup I made with the backup/restore plugin. All of that went fine. When I restarted docker, it didn't see any containers running. I stopped docker and went back to a share I created for docker to run in cache and changed the "Use cache (for new files/directories):" to "only"(This share existed before cache drive swap). That is when I noticed that my array of 90tb was now using the exact amount of data that is on the cache drive which is about 90gig. Am I hosed? unraid-diagnostics-20210916-1630.zip
