I replaced a 2TB disk with an 8TB disk and added it to my array. Everything seemed fine.

 

I then used Unbalanced to transfer all contents from a 4TB to the new 8TB disk. The process finished successfully. I then stopped the array and unassigned the 4TB disk. When I started the array back up the new 8TB disk is showing as unmountable and is asking to be reformatted.

 

I ran xfs repair from the GUI twice but it failed both times. (attached) I've attach my diagnostics file as well.

 

The disk in question is: 

WDC_WD80EFPX-68C4ZN0_WD-RD0M8AUE (sdf)

 

What are the next steps I should take to get the disk to mount?

Start by running memtest, to make sure there's not an obvious RAM problem.

I've been googling for the past 15 minutes to find instructions on how to run memtest and haven't found a reliable process.

 

Here is what I found:

1. Using a new usb stick put https://www.memtest86.com/ on it
2. Reboot my machine with the stick plugged in and enter the bios (using a keyboard and mouse)
3. Select the usb to run memtest?

Is that correct? Do I need to format the usb stick to work correctly?

You can select the memtest option in the Unraid boot menu.

I ended up using the Live Memory Tester and it's gone through several loops with no errors. It doesn't seem to be the RAM.

 

Is there something else I can try?

You can try updating to v7.0.0-beta since it includes newer xfsprogs and see if xfs_repair can then fix the filesystem.
