March 28, 20251 yr Author I'm not getting the option to stop the array currently. It seems the mover is running which may not be good. my docker apps started up overnight and I believe things started downloading again.

March 28, 20251 yr Community Expert You can redirect the output to a text file, then attach that, e.g.: xfs_repair -v /dev/md2p1 > /boot/xfs_repair_d2.txt
March 29, 20251 yr Author 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
March 29, 20251 yr Author 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?

If yes, are you sure you typed the command as written above? xfs_repair -v /dev/md2p1 If both are true, xfs_repair is unable to repair the disk, if you have important data there you can try a file recovery util like UFS explorer. Disk1 needs to be rebuilt, it already started, you just need to wait for it to finish.

Disk1 needs to be rebuilt, it already started, you just need to wait for it to finish. 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?

Yes 3 minutes ago, BillPlott said: Will that then allow me to rebuild disk 2 after reformatting it? Rebuild will not recover anything from disk2. If you want to try to recover files from that disk you shouldn't use it in Unraid again until you have tried to recover its files with UFS explorer or something. If you want an empty disk2 to work with you could rebuild disk2 to another disk and format it after rebuild. Or, you could remove it from the array with New Config and rebuild parity instead.

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.

March 30, 20251 yr Author as another option to re-formatting disk2, can I replace it with a new drive and rebuild the data still?

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. Edited March 30, 20251 yr by BillPlott more info

Browse into disk1, then for the lost+found folder, click + under Action, select Calculate from the popup, and post the result.

March 31, 20251 yr Community Expert When repair can't determine what folder a file belongs in, and/or what the name of the file/folder is, it puts it in lost+found, perhaps with a random name. Linux 'file' command can help determine what kind of data is in a particular file so you can try to open it with an appropriate application to see if you can identify it. Often less trouble to just get those files from backup. 15 hours ago, trurl said: Original disk1 might also be useful depending on what and how much of disk1 repair ended up in lost+found. Will original disk1 and disk2 mount as Unassigned Devices?
March 31, 20251 yr Author 37 minutes ago, trurl said: Will original disk1 and disk2 mount as Unassigned Devices? 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.

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?
March 31, 20251 yr Community Expert 4 minutes ago, BillPlott said: do I just move them to their appropriate folder in my Media share? If you know where they belong. Only really important to get that exactly right if some container or something is expecting to find them somewhere in particular. 5 minutes ago, BillPlott said: is there a way for unraid to figure that out itself? No, it doesn't know anything about individual files. All it can see is the same thing you see in lost+found.

That is your array now. I have a single disk USB enclosure that works very well with Unassigned Devices. If you already have a way to connect those with USB that would be worth trying.

All it can see is the same thing you see in lost+found. 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.
