June 4, 20242 yr I need urgent help please. I don't know what happened, but seemingly after a parity check, ALL of my data is gone. I used to have roughly 30TB used on my array, and now its showing basically none of it is there. I don't want to touch anything because I'm scared I may not be able to recover it. Attached is my diagnostic. Please help me. lafayette-diagnostics-20240603-2132.zip
June 4, 20242 yr Community Expert Parity check doesn't do anything to the data, do you have you server opened to the internet?
June 6, 20242 yr Author Not directly. I do have Nginx reverse proxy running. The only port I have forwarded is port 443, and in cloudflare I'm using their proxy as well
