April 10, 20251 yr Hi all, I've been reading on the forums to see if there is a fix for having a disk with the status of "Unmountable : Unsupported or No File System" but I found different solutions due to circumstances. Here is the series of events: 1. Upgraded from 6.12.13 to 6.12.15. 2. Array came online but noticed one of the disks showing a status of Unmountable : Unsupported or No File System. 3. Restarted the array just to see if it would make a difference and it didn't. 4. Put the array in maintenance mode. 5. Ran check disk. It came with the following info. <?> Phase 1 - find and verify superblock... would write modified primary superblock Primary superblock would have been modified. Cannot proceed further in no_modify mode. Exiting now. <?> I am not sure if I should perform the repair yet. I have attached my diagnostics too. Thanks for the help. atlvmmd01p-diagnostics-20250410-0652.zip
April 10, 20251 yr Community Expert Solution Run xfs_repair again without -n, or nothing will be done.
April 10, 20251 yr Author Thanks, I have attached the output here in a text file. Looks like it is all good to go. After running it I did the following: 1. Stopped the array 2. Started the array taking it out of maintenance mode. 3. Disk came back into operation. 4. I can now browse the data that is on that disk. I appreciate you taking a look at my post. unraid fdisk.txt
April 10, 20251 yr Community Expert You should now look to see if you have a Lost+Found folder on the drive (which will appear as User Share with the same name). That is where the repair process would put any files/folders for which it could not find the directory entry giving the correct name. Not having that folder is a good sign that things went well.

Oh okay. I assume I can view this from the GUI by clicking on the browse icon next to the disk? If you mean from the Shares Tab --> User Shares. I do not have a new folder there. On the disk itself, it does not have a folder called Lost+Found. Thanks for that insight.
