Trying to expand storage. Purchased an expansion card and connected 4 additional drives. Initially it all seemed to work fine. Then 1 disk was showing errors on the Unraid gui. So I swapped it out and the "new" disk was showing errors. I wasn't sure if I had 2 bad disks, or cabling or new card. I took drives out of the internal storage and swapped them with the external drives. That actually caused another drive to go bad. I'm thinking something was up with the cables maybe? Or coincidence. I've since replaced the cables with new ones from a trusted source.  

 

When I click on the drives after Starting array in Maint mode. Clicking on Check disk results in an error superblock read failed, offset 0, size 524288, ag 0, rval -1 fatal error -- Input/output error. I'm getting this for both disks in question.  However Disk 1 is showing a red X and disabled. And  Disk 12 is saying contents emulated. When I started the Array without the Maint box checked. Its prompting to format the drives.  I don't mind formatting disk 12 if I have to, but Disk 1 had a bunch of data and I rather not lose it. But if i have to it won't be the end of the world.  

 

I saw in another thread they were using xfs_repair.. But I am not sure on what I need to run it against? They were doing md1p1 I think it was? I'm not even sure what that is in reference to. 

 

Any advice or direction would be greatly appreciated.  Thank you

You have tow invalid disks with single parity, so they cannot be emulated, you can see if the actual disks are mounting OK with UD, and if yes do a new config to re-enable them.

Only 1 disk is coming up as emulated. And that disk is actually new to the array.  Disk 1 though is disabled. I believe something happened with a bad cable that caused errors and corruption. I replaced the cables but not sure how to fix the "Superblock read failed" error.

They are both invalid, so neither can be emulated.
