I don't fully understand the process above without context (apologies). Is there a guide on just starting completely fresh?

Initially I was thinking start completely fresh but if there is an good way to keep the dockers then that would be great. Thanks you

Understood, thank you for explaining. I thought I had done something or misunderstood the process. I take regular backups so thinking I may start fresh the whole build and then copy the data back on. Is there a guide on wiping/starting again from the same USB key? I did have a search but nothing really along those lines. Thank you again for the info.

I'm so confused, I thought unraid should be able to recover from disk failures, have I done something wrong stopping the recovery?

The disk rebuild completed, final message was that it completed successfully without errors but then we looking at the disk status it states "Unmountable: Wrong or no file system" but yet the disk rebuild was apparently successful. Is there anything that can be done about the wrong or no file system issue? Thanks in advance

Sorry if this is a stupid question but how do I see what is emulated on the disk before the rebuild? Would the status of Disk 1 show something like "Emulated disk"?

I stopped the array and unassigned the disk, started the array and disk 1 now showing "Not installed". Stopped the array, added backed into to disk 1 slot, started array and now "Data-rebuild in progress" In your experience, would you expect this to be successful?

Really sorry to be asking lots of questions, I appreciate your time. How would I go about rebuilding the disk using parity?

OK thank you, is there no way to rebuild the disk from the parity drives?

Thanks JorgeB, I ran the check with the nv switch, result was "...Sorry, could not find valid secondary superblock." I ran the above using the web GUI, should I try from SSH/Console?

Sorry, bit later getting home. I've rebooted and taken fresh logs. Hopefully these are not as cluttered. unraidhp-diagnostics-20230319-2056.zip

Sorry JorgeB, as soon as I'm back home later today I'll reboot and get fresh logs. Thank you for looking.

Long time reader first time poster, apologies if I do not list everything in the first post but I will try to capture everything. I initially had a HP DL380 G8 server, all disks were sitting behind a disabled RAID controller, everything worked well. I was away and something caused a failure, after some investigation it seemed I had two SAS drive failures and a mainboard failure. I read a few articles at the time and (from memory) the best route was to move to new hardware as the replacement board was too expensive to replace. When I moved to new hardware I had to create a new disk config as the drive serials appeared different due them previously being behind a RAID controller, I was unable to add the two failed SAS drives as they were completely dead plus the new hardware did not have a SAS controller. I did/do have two parity drives and the data all appears to be in tact but I know I need to replace the drives as currently if any more fail then I know I am going to be screwed. I have tried to pre-clear a new drive and add to the array but I get "Unmountable: Wrong or no file system" for the new disk. Any advise or suggestions greatly appreciated.
