Hi, I did an upgrade to my server adding another 4 Tb drive and an SSD cache and in the process had to unplug all SATA cables and they didn't go to the same ports or drives. The server boots but there is a drive that has been giving me errors first showed as unmountable: not mounted.

      I then tried to repair the file system following the XFS repair guide. I didn't mind losing the data because it wasn't my parity drive. After attempting repair the drive now shows up in Unassigned Devices. The drive in question is Dev 3 (ST4000VN008_ZDHA5SV9. I've attached a screenshot of what it shows now and my diagnostics log. Do I run preclear to empty it than reformat it or am I screwed?

 

Thanks, and let me know if you need any more info!

add drive clarification

Disk appears top be failing, don't format anything, replace/swaps cables and post new diags after array start.

I did a couple of cable swaps and this is my current diagnostics.

I can now add it back to the array but there is a little blue square next to the Device Name that says when hovered over "New Device."

Disk still appears to be failing, it's not even giving a valid SMART report, good news is that the emulated disk1 is mounting so you just need to replace that disk then assign it to the disk1 slot to rebuild.

Thanks, I have a drive ready to go in the array, but I did an extended Smart test last week and it came back as healthy. I'll try to post that after work but if it is dying I guess I will try to rma it.

I removed that problem disk and added the new drive to the array. When it started the rebuild it was moving extremely slow and sounded like something was grinding in a pulse pattern. None of my data is critical, would it be better to wipe and start new. I have attached a new diagnostic file.

Check/replace cables on parity and try again.
