ah ok, thank you for your guidance, I`ll try to backup everything and re-check everything.

Are you saying Disk 6,5 and 1 possibly hardware failure? Because I just bought it recently, the oldest one is Disk6, around 4 months ago, Disk5 2 months ago. Disk 1 just bought it last week. Or seagate I bought is just shit?

Thanks, that's what I thought too, probably a lot easier to start from scratch, and install everything again from there. Any guidance on what I can do now? I'm not sure how to wipe clean and restart unraid after backing up.

I will try again tomorrow, I have some cables somewhere in office and will try that. I have swapped the sata cables but still unmountable. I havent tried to change the molex to sata adapter to power the HDD. I see numbers and most of it are empty. So it's good to say that disk6 is empty and I cant recover anything? EDIT: Side note, now the error is gone, just that 2 disks are unmountable

Unfortunately this is my best backup unraid has been reliable protecting my files. Should I try to back up whatever's left?

nope never.

I changed the cable, changed the sata slot on disk5, still unmountable. mynas-diagnostics-20210913-2038.zip

It all started with Disk 1 died, so for a few days while waiting new disk comes, content is emulated. Now that it has come, opened up the case, swap the disk, suddenly Disk 1 becomes unmountable: not mounted. Weird it's a new disk, so I swapped the cables for it, somehow disk 5 and 6 follows, becomes unmountable. So I read up here https://wiki.unraid.net/Check_Disk_Filesystems#Checking_and_fixing_drives_in_the_webGui I did the xfs-repair. Not sure how I did it, suddenly disk 5 and 6 loss all data, if you see screenshot above that disks 6 has 56gb used. originally both disk 5 and 6 has almost full disk. Is there anyway to recover those files? Panicked, I try to upgrade UNRAID to the latest RC version, only to kill my USB. I changed my USB to a new one, and copied the config to the new USB. Screenshot are all from the new USB. Anyway, I dare not do anything else as of now, here I seek guidance on how should I proceed. I noticed photos from 2008 are gone, probably because they're on disk 5 or 6. Right now the system is doing parity rebuild, but the speed is horrible. mynas-diagnostics-20210913-2001.zip here is the diagnostics, not sure if it any helps. Weird part that I notice is that all these happens to Seagate IronWolf disks.

Sorry for the late reply, yes I do but only 1 file.

Got it. Thank you for the explanation!

I did it via GUI terminal. It looks for secondary block and all it does is giving dots ....................... and never stops. I canceled it via ctrl + z. I hope I'm not making any mistake there?

IT COMES BACK NORMALLY. THANK YOU SO MUCH KIND SIRS @JorgeB and @itimpi! Edit: how do I mark it as solved?

Ahh alright, it does it's thing now. I used the option -vL there. What should I do next?

So this is what I got from the first checkup. Doesnt look so good. Trying to do xfs_repair -nv /dev/sdb now

Yep as other people who have similar issues I dare not touch until I know what I need to do. mynas-diagnostics-20210309-1800.zip After a restart this is what happened to sdb I tried changing the cable but still the same. I wonder how should I proceed from here? Do I need to xfs_repair -v /dev/ something? It's been few days because I didnt have the time (work) to fix this immediately. I wonder what would happen to my data? Anyone can fill me here? Thanks!
