Unmountable: No file system

[indy5]

Good day Unraid Community,

 

For, for a bit of background that may have led to my current situation. I have been running a stable system for many years, gone through many drive upgrades, hardware replacements, etc. This past weekend I moved my entire system into a new case, installed a new drive controller (Adaptec 71605). After completing this process, everything was working properly, all drives detected, array started successfully.

 

At some point after things were working, after a reboot, one of my drives went Unmountable.

 

I started the array in maintenance mode, tried running xfs_repair via UI. The repair ran overnight and ended with a message that a Secondary Superblock could not be found.

 

I am not sure what else to do at this point and I want to make sure that I don't disturb anything, if there's a chance I can save the data.

 

I appreciate any help. Diagnostics are attached.

That suggests a damaged superblock, connect the disk to an onboard SATA port just to make sure it's not controller related and please post xfs_repair output.
