In particular, I didn't have much time for the forum yesterday. RAID controllers are not recommended for many reasons, including these exact problems you encountered when you changed controllers. Since you had to New Config, you can't rebuild anything except parity. Did you assign the original disk4? Attach Diagnostics to your NEXT post in this thread. Quote Link to comment
Goreliann Posted February 11 Author Share Posted February 11 I figured people were busy so I just tried some research of my own while I was waiting. So far everything seems to be ok. I assigned the original Disk 4 and all seems to be running through parity-sync with no issues. I've got a similar circumstance to one I had earlier in this thread where one of my folders was empty while parity was rebuilding, but last time that sorted itself out once the sync was complete so until then, I'm not worried. This may be using a RAID controller, but it's functioning more as a SATA splitter than any actual RAID control. So far all seems good. I'll know more once the sync is complete. If that all works then I'll be looking to add Disk 1 to expand the array since Disk 4 now seems to be working properly. I see no errors or warnings. Here's a diagnostics in the meantime. Sync should finish in another 12 hours. 16TB parity drive. Oy vey. storage-diagnostics-20240211-1513.zip Quote Link to comment
Goreliann Posted February 11 Author Share Posted February 11 Oh and thanks again for helping with this. You've been invaluable. Quote Link to comment

Parity sync has nothing to do with your files and folders, it is all just bits as far as parity is concerned, and sync has no effect on your data disks. Quote Link to comment

Except that they're not. Once the sync was completed, I rebooted the system, started in maintenance mode, ran a filesystem check/repair on Disk 4 (which failed again like last time this happened), restarted the array normally, and all the files are back now. I don't explain it because I'd agree that sync has nothing to do with missing folder contents (even though the folder itself is there). All I know is that this is twice now that this process has worked so I don't know what's going on. Everything seems to be working properly now. Go figure. Here's a diagnostic. Maybe you can figure it out. storage-diagnostics-20240212-1158.zip Quote Link to comment
trurl Posted February 12 Share Posted February 12 Filesystem corruption and parity sync are also unrelated. What do you get from command line with this? du -h -d 1 /mnt/disk4/lost+found Quote Link to comment
Goreliann Posted February 12 Author Share Posted February 12 I don't know where to enter that command. I do, however, notice a lost and found directory when I use the unraid file explorer on Disk 4. There are definitely some files in there, but not that many comparatively. Quote Link to comment
trurl Posted February 12 Share Posted February 12 I know you have lost+found. That command will tell you the size of that share and its subfolders. On the main bar of your Unraid webUI, mouseover the >_ You will see that it is Terminal Click it to get a browser window at the command line. Quote Link to comment
Goreliann Posted February 12 Author Share Posted February 12 Looks like 86GB. I can live with that. Is there a way to get those files out of the lost and found or do I have to replace them all? Quote Link to comment
trurl Posted February 12 Share Posted February 12 The linux 'file' command might be able to tell you what kind of data is in each file, then you can try to open it with an appropriate application to see if you can identify it. If you drill down into those folders you might find some things that still have the correct names. You can move them to their correct folder on disk4. Each user share with files on disk4 will have a top level folder named for the share. Looks like the only user share you have besides the defaults and that newly created lost+found share is M---a shareUseCache="no" # Share exists on disk2, disk3, disk4, disk5, disk6, disk7 I'm guessing that is Media.

Goreliann Posted February 12 Author Share Posted February 12 So I can terminal command copy these to their proper folders? Do I have to do it that way or will a Windows samba connection work? Quote Link to comment

Do I have to do it that way or will a Windows samba connection work? Any method you like. If doing it via Windows you might first need to run Tools->New Permissions on the Lost+Found share to ensure the permissions are correct for doing this over the network. If you want to do it locally on the Unraid server then the Dynamix File Manager can be used. Quote Link to comment

Goreliann Posted February 12 Author Share Posted February 12 I have no idea what it's actually called. I just explore the files on the Main screen. Either way, I used the Terminal to copy everything to where I can manage the files via Windows. I seem to have figured it out. I've also found there's a lot more missing than just what's in the lost and found, but again, comparatively little so I can live with that. I'll just go about replacing it all. Thanks for all your help. Quote Link to comment
