Problem: Disk1 - Error with red X Disk2 - Unmountable/bad filesystem Solution: Disk1 - Repair filesystem and rebuild Disk2 - Reformat as repair to filesystem failed.

Disk1 finished rebuilding and is operational again. For Disk2, I was going to reformat it next - I believe you said it wouldn't be able to be rebuilt after that right? so, it will start fresh and I can pull data off my original disk2 once I find a method to mount it (or simply re-download the data I'm missing) tower-diagnostics-20250331-0939.zip

OK so it would prevent me from having to re-download files by taking them off the mounted disks and putting onto the array. got it!

Ah - OK, I'll see what I can do an an additional option to attach via USB. I don't currently have any hardware to plugin in a drive via USB. if I do get them to mount, what would be my steps after?

OK - I COULD go through them manually, just is a lot of work. I can see the TV show or Movie names so I could move them accordingly, just a lot of work. If I delete the files, I assume they will get redownloaded when my Media is scanned.

I browsed some of the folders in lost+found and recognized the file names, just not sure what to do with them. is there a guide somewhere? do I just move them to their appropriate folder in my Media share? since there's hundreds of folders/files, is there a way for unraid to figure that out itself?

I'm not sure I can at this time. Only have 8 sata ports available and they are all being used I have 4 from the MB used, and 2 additional sata cards in pci slots to provide the extra 4 ports for my 8 disks. I would need to take the server down, replace the new with old disks and attempt to mount. I'm waiting another 4-6 hours for Disk1 to finish rebuilding before doing any next steps. If formatting Disk2 gets my array working again with 6 fully operational drives, I'd be satisfied, even if I need to re-download a couple TB of movies/shows again. Replacing the new with original disk2 would get most of my data back, but would have to rebuild the new disk after a parity check anyway right? if I can avoid swapping parts at this point, i'm fine with that.

The above was from clicking on the lost+found folder and scrolling to the bottom. This is from the calculation: Name: lost+found Location: disk1 Last modified: 4 days ago Total occupied space: 1.77 TB in 1661 folders and 14,762 files

Disk1 - 1359 objects: 941 directories, 418 files (290 GB total) this is out of 5.65TB being rebuilt.

yes, I still have the original 8 and 4 TB drives from before. However, I'm sure some new data in that week between replacing the 4TB drive, rebuilding it, and then replacing the 8TB drive was put on the array.

as another option to re-formatting disk2, can I replace it with a new drive and rebuild the data still?

If I understand correctly, and I'm fine to lose the data on Disk2, could I not check the box to Format the unmountable disk to create a new file system and wipe all data for it to be used again? any movies or tv shows that I lose would just be re-downloaded again anyway.

yes, I ran the command (copy+paste) and it ran for over 12 hours each time (I did it twice). The output file is blank (0kb). end of console output: Sorry, could not find valid secondary superblock Exiting now. I'm going to let Disk 1 rebuild. When that finishes, does it change from an emulated disk to a normal disk? Will that then allow me to rebuild disk 2 after reformatting it?

Can someone describe what is actually happening (root cause) or analysis of why Disk 1 is being emulated? Is this a problem that will be fixed? Will I have to clear Disk 1 or 2? Are these drives usable or is my array lost?

not sure the file is needed for output as the final message is Sorry, Could not find secondary superblock. I'm also drawing a blank how to get the file off for review. I moved it to my Media share to try to copy it from my Windows PC, but I'm failing to connect to the share. Attaching diagnostics for before shutdown, (I then confirmed all cables to the drives were secured) and after starting the array again. tower-diagnostics-20250329-0950.zip tower-diagnostics-20250329-1018.zip
