Update:
I ran a parity check twice over the past couple days and each time the parity drive showed up as 3TB with no errors. I figured it was safe to replace the smallest 250GB drive with another 3TB since it appeared that the problem had went away.
I physically replaced disk 9 with another of the same brand 3TB drives and when it booted up the parity drive was recognized as a 2TB drive that was "wrong". Its the same serial number so I'm still experiencing the problem.
I attached a copy of the diagnostic report.
- I don't believe its a sata port issue but I'm using 4 ports on a Gigabye GA81945-PL-G with two 4 port PCI cards for a total of 12 drives. I can get the brands of the cards if that might be the problem.
- I originally thought it was the old version of unraid but I upgraded that first so I know that's not the issue.
Any more thoughts. I'm thinking of trying the second 3TB hard drive I have as the parity. The only problem is that drive is also recognized as 2TB right now so it probably has the same issue.
