Alright, so I was seeing this: Per unraid instructions, went to do an XFS repair on md2 (because that's where logs were showing issues) and seeing this: So I guess I will just replace disk2 when i get home and rebuild to that.

Looks like that'll be a bit. Disk1 is not giving me errors, but Disk2 is now having read errors. I just got a new 10tb in yesterday, so I am going to get that in and replace Disk2 since it's having active read errors now. These HGSTs have been sitting around for a bit and weren't tested, so I guess that's a failure on my part since they are obviously both bad.

Alright, so it finished. There were 35 errors and it appears disk1 is also bad. Given it had water damage (replaced PCB) and all that stress, I'm not surprised. I've got a couple more drives on order to get everything up and safe. Disk2 didn't show any errors on rebuild, so it should be good, for now. It appears I am mostly in the clear though. unraid-diagnostics-20220910-0850.zip

Oh yeah, much better now

I do. So just stop the re-build, replace with the other drive, and rebuild again?

Got it to speed up a good bit by disabling docker. Probably some of my containers trying to do things. Diags attached unraid-diagnostics-20220909-1012.zip

Going Slowly 🥲

Fingers crossed. Started rebuild with new disk. Thank you for your help! Sent over some beer/pizza funds as thanks.

Ok, so it started. And everything looks ok at first glance and a few spot checks? Requested diags and SS attached. Roger. I am going to stop it for the night. unraid-diagnostics-20220908-2238.zip

Ok, to confirm, do not check maintenance mode. It also wants me check this to start it:

Alright, Done with all those steps. Screenshot:

Ok, i am out for about 3-4 hours and will begin that when i get back. In the event Disk1 is bad, this would not do anything to the parity disk, correct? I ask because the old Disk2 may be repairable I am still looking at purchasing another WD100EZAZ drive and taking that PCB, swapping ROM IC and fixing it. i guess i could just mount disk1 and look at its contents to somewhat verify it’s ok?

unraid-diagnostics-20220908-0855.zip Attached, apologies I dropped out yesterday. It was late over here.

I do. 10-4

Ok, so I had a crazy AC leak and two of my three drives got wet and the PCBs fried. I had one parity, but two drives failed. I have since repaired one of the two bad drives (swapped ROM IC to a new donor board) and want to rebuild parity, but unraid has forgotten one of the disks. Before I go any further and bring confusion, I am going to start with my disks and their status 10Tb Parity - Good and healthy 10Tb Disk1 - Repaired and appears to be fine, but unRAID doesn't "remember" it? 10Tb Disk2 - Bad and missing. So as you can see. Parity shows good. Disk1 (MPN) which is the original disk, has been forgotten for some reason. Disk2 (2MZ) is bad and I plan to replace with a good 10Tb drive. What I need to do is get unRAID to "remember" Disk1 and rebuild to a new disk for disk2. How do i do this? I do not have any config backups. Any backups I had were on the array (lesson learned there). What can i do? Help me Tom Cruise, please and thank you!
