Wanderer

Awesome! Thanks a lot! It worked! I was able to create a temporary mount point and copying the whole disk manually for now. So, what could have caused this? Would it be a faulty disk issue or just the btrfs filesystem that's not reliable?

I added this new disk drive as a cache a couple months ago. Everything seemed to be working fine with no errors detected from Unraid. Then 2 things gave away flags about the drive condition: 1) (not really sure if it's related to a disk problem or a docker setting but) every new file created was given a unknown permission and I had to run the "New Permissions" tool every time whenever I needed to do any modifications on the files; 2) Since this morning, the drive became write-protected. I couldn't write on it but could clearly read all the content, no problem. I then tried to reboot the server, and now the drive is giving me the "Unsupported or no file system" error and cannot be mounted. Any help would be appreciated! unraid-diagnostics-20240911-1323.zip
