Hi again. System finished rebuilding. Looks like everything is back to normal. Again, thank you very much for your help! btw: Not sure if I can mark one reply as 'solution' as there were lots of steps to follow. Any suggestions to help the next user?

"Parity operation is running estimated finish 6 hours, 5 minutes" You guys are the best!!! Thank you so much!!! 🥳

So I just stop the array, add the new drive as disk 2 and start the array? It says: "Start will start Parity-Sync and/or Data-Rebuild." behind the start button. that sounds right, doesn't it? (Again sorry for so many questions about stuff that is obvious for you, I guess. I just don't want to do some big f*** up at the last moment.)

Those 12 files in the lost+found folder were random music files I don't need. I was even able to download them using the giu. This is all pretty amazing to a noob like me. ☺️ The old disk was not mountable at all. Just vanished as soon as I tried to mount it.

here is the file and a screenshot of the lost & found folder. tower-diagnostics-20240311-1724.zip

Again, thank you, and, again, sorry for more questions. But just to be sure, normal mode with parity and both data disks in the array?

OK, done. should I upload a log file? edit: I did the check without -n. It didn't ask for -L. Here's the data that showed on screen. Thank you both again!! Awesome! check_filesystem_status.txt

Sorry for stupid questions, but how do I do that? according to the manual I need to start the array in maintenance mode. is that correct? Right now disk 2 shows as not installed / unmountable and I see nothing to do a check.

here we go. tower-diagnostics-20240310-1420.zip

Thank you! So, I'll try to summarize what I understood so far about my situation, just to be sure, that I'm on the right track here. If I'm lucky, I have a valid parity disk and one of two data disks. Now I need to tell the system to recreate the second data disk from the before mentioned two disks. As my configuration from my old setup is gone due to the failed flash drive, I somehow have to make sure, that unraid knows wich one of the data drives is valid and wich one is new/replaces the broken one, so it rebuilds that one and not the one with my data on it. Am I correct so far? Question is, how do I do that. 😨

Hi, the old (failed) drive (a Seagate) does not show anymore. or rather: As soon as I try to assign it to the array, it vanishes. Because of that I removed the Seagate from the server altogether. The WX22D83RHEP8 is the new one I bought to replace the Seagate. Should I try to reinstall the failed drive again, before starting the Steps you mentioned? Thanks again!

sure thing! here are both. tower-diagnostics-20240213-1757.zip tower-diagnostics-20240310-0859.zip

Thank you so much for your help! What part of the diagnostics file should I post? The whole zip file seems a little bit to much. Btw, I actually have a diagnostics zip file from between hdd and the flash drive failure. Can I find anything helpful there?

I think it showed something like not connected

I didn't disable it. I hope, that is what you ask?
