Unmountable Disk, unable to verify superblock

[SpyisSandvich]

Hello

 

I have a disk showing up in my server as Unmountable.  It's otherwise still showing green and doesn't have any errors listed in the Main tab.

 

I've started xfs-repair through the unRAID GUI.  It's still running but it's stuck on the following step:

Phase 1 - find and verify superblock...
bad primary superblock - bad magic number !!!

attempting to find secondary superblock...
...found candidate secondary superblock...
unable to verify superblock, continuing...
(this line is continuously expanding with `.` characters)

 

I've collected the diagnostics and attached them.  I'll update when I notice the check finish, but it seems to me like it's probably going to run through the entire disk before failing to find a superblock.  Assuming this is the eventual outcome, how might I go about fixing this drive?

 

Some context, I needed to shut down the server yesterday because CPU consumption somehow spiked to 100% on all cores and even the web GUI wasn't being responsive.  There's a strong chance that this caused the issue on this drive.

You have to let it finish with the continual dots.

 

Assuming you didn't remove the "-n" flag, that'll be the next thing you do and run it again.

I figured as much.  I didn't remove the -n flag.  Will update when it finally finishes.

If the GUI gives you the option to cancel (I really have no idea) I would.  Since it's unmountable, it's going to tell you to remove the -n anyways.  Do that and re-run  Saves some time.

It does give me the option to cancel, so I did.  Removed the -n flag and running it again.

 

EDIT 2:  The check finished, looks like it didn't find anything.

Exiting now.

Further development, or unexpected lack thereof

I've updated my previous post, the check finished predictably.

 

In the meantime, what's the risk of running the server provided I don't use the broken drive?  The data on there isn't the most critical on my server, but keeping it in Maintenance mode (or off, since I'm still unsure about what to do next) has obvious impacts to usability.

I'm going to continue to use the server despite the unmountable drive. As long as it's not being mounted and, crucially, I exclude all shares from using that drive, it should be okay, right?

 

Right?
