I'm posting this here to make it easier for people to find and easier to post the details for the ticket I will open. EDIT: Here's the ticket https://support.freenas.org/ticket/1234
Background: This is a 5 disk raidz2 with 4x 2TB Samsung disks and 1x 2TB Hitachi disk that was created on version ~8.0.
Problem: Replace disk from GUI fails without explanation when using identical 2TB disk.
After doing replace disk from GUI, there is no apparent resilvering activity taking place. After trying replace command from the command line, I got the error "disk is too small". When doing a gpart show, I discovered the problem was that 8.0.3-p1 created a 2GB swap partition as opposed to the 1GB swap partition that was created when I initially created my pool from the GUI in version 8.0. So it seems that the GUI needs to check existing swap partition size and makes sure it creates the new one consistent with the size on the other disks. I manually wiped the disk and recreated the partitions and did the replace from the command line using the same command that was issued from the GUI in the log file.
Here is the log file and output from gpart show etc.:
