Sudden Total Data Loss after parity check

Featured Replies

Posted

 

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.

Parity check doesn't do anything to the data, do you have you server opened to the internet?

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

The other typical case that can cause this is a container like Plex or similar doing media cleanup, if you don't have backups you can try recovering the data with UFS explorer.

Is there any way to prevent doing that in the future? I was waiting for my n100 board to build my backup target, but have UFS scanning the first drive right now

If you are still not sure what caused it, and the data is mostly WORM, you can set the files to read only after transferring them:
