Replacing a failed drive

[ozo]

I'm using FreeNAS 9.3.

I had a drive fail on me, and I just received a replacement. The problem is my 2TB Seagate Green drives were long out of warranty, and rather than buying a used one on eBay I bought a new Western Digital Red drive.

When attempting to replace the drive (using the instructions here), I'm getting the following:

​

I Googled around for a while, and I found how to compare the # of bytes on the drives -- they appear to be the same. I'm guessing there's more to it than that.

Is there anything I can do to make this drive work?

Thanks in advance!

You can reduce the swap size. But in theory this drive should work, there's maybe another problem than just a difference in bytes number, wait for another answer to confirm ;)

 

[SweetAndLow]

Your old drives are using aa 512 sector size and the new drive wants to use 4k. I suspect this is the problem. Not sure what to do about it without doing some research.

Thank you both for the quick responses! It's resilvering now... (Please let me know if I should do something different.)

After reading what Bidule said, I started reading about swap. I read something earlier that mentioned that old versions of FreeNAS didn't create a swap partition when you set up the drives. Is that true? It reminded me that although I have upgraded the OS, I originally set up the pool back in 2010 (I think version 7.1 or 7.2).

Anyway, I did fdisk on one of the old Seagate drives to see the partitions. It doesn't appear that I have a swap partition... right?

I set the swap to 0 for new drives from the GUI and did the drive replace process again and it worked!

For reference, here's the partition table for my new drive.
