Thanks for all of the assistance. All of my user shares and dockers are back.

Thanks for looking into my issue. I've restarted the array in normal mode and it appears that the shares are back, but the docker service failed to start: I've attached the latest diag.tc-nas-01-diagnostics-20211026-0701.zip

Hi, I increased the docker .img size from default for no particular reason... just did it because I had the space at the time. Anyway, I just rebooted and it gets even "better". ALL shares are gone now - disk shares AND user shares. Post reboot diag attached. tc-nas-01-diagnostics-20211025-2010.zip

Hi, this just happened literally minutes ago. I've been having issues with my Unraid server and a corrupt file system on disk 2 for a while now. I ran the fixdisk utility and it came back with a whackload of files in the lost+found folder. Long story short is that I decided to rather than go through the thousands of files and folders, that I would re-import the data to the array. Anyway, my server has been busy, pulling over 3TB of data in the past few weeks and fast forward to just now when I realized that my cache drive was full. So (stupid?) me started a mover, then went to the share that was the culprit of the full cache and set the cache method to "no". Upon hitting "apply", I was greeted with "Share Deleted" instead of the usual blip and return to the share window with the new setting. I went back and looked at my other shares and they are ALL gone! Only disk shares remain. HELP!!!!! 🙂 Is everything gone? Is there a way to restore the shares/configuration?

Excellent - thanks. We can consider this "closed" now. Thanks again for all of your time and help on this - exceptional!

Update: I've tried XFS Explorer and found hundreds of folders and files that were corrupted - thinking of purchasing the software as it's not very expensive and appears to be quite useful. That said - In looking at what remains on the array, there is nothing critical missing. While the disk 8 was being scanned from my desktop, I assigned a fresh drive in it's spot in the array. Of course it did the rebuild and came back with the same "unmountable" error. Since I am OK with losing the data that was on Drive 8 - would there be any danger in formatting this new drive 8 to be used in the array? Or is there a better way to make the drive 8 spot usable again?

Gotcha, Well, thanks again for all of your help - I'll check out UFS Explorer. I'll start the array and see exactly what files are lost - At this point, I think it will be best to just reformat disk 8 after seeing what can be salvaged using a recovery tool... We'll see.

Well - I left it running and went into the office... just got home now and it has completed unsuccessfully as you had suggested it would. Here is the output from the status pane in the GUI (minus a gazillion "."'s for readability): Phase 1 - find and verify superblock... couldn't verify primary superblock - not enough secondary superblocks with matching geometry !!! attempting to find secondary superblock... .found candidate secondary superblock... unable to verify superblock, continuing... ....found candidate secondary superblock... unable to verify superblock, continuing... .................................found candidate secondary superblock... unable to verify superblock, continuing... .........Sorry, could not find valid secondary superblock Exiting now. So is all the data on the drive toast?

Thanks - it's running now (with -v option):

You're right - and interestingly, I don't have the option to run a check on this drive from the GUI - the menu section to do the check is missing completely: Here it's showing fine for disk 9: Is there a way to execute a check on it now if it's showing "No file system"? The filesystem on drive 8 was definitely xfs prior to this issue. Latest diag attached. tc-nas-01-diagnostics-20200224-0714.zip My continued thanks for all of your help.

Update: Disk 8 has finished rebuilding with 0 errors. (according to the GUI notification) I haven't refreshed the GUI, but it's still showing that drive 8 has an unmountable file system - I suspect that may change if I refresh the GUI, but I will leave it as is and wait for your next instructions. Thanks.

Thanks for your time to provide these instructions... very much appreciated. 🙂 I will try it in a few minutes and report back when it's done.

Hello, New LSI controllers have been installed and the system is powered back up and appears to be in the exact state it was left in. What would next steps be to try and recover disks 4 & 8?
