Hello, I have a 16 disk RaidZ3 arrary that had a mix of 3TB, 2TB, and 1.5TB disk units in it. I was getting 15.5TB of usable space. Then I replaced the last 1.5TB disk with a 3TB disk and set the autoexpand flag to on. I shut down my system to replace the 1.5TB disk with the 3TB after the resilver and rebooted. but I am only getting 20.7 TB of space. My other arrary 15x2TB RaidZ2 is getting 22TB of usable space, so a 16x2TB RaidZ3 should be getting the same right? Am I missing something?
The Idea was to get more space now, as I find deals on new 3TB disk I would replace the smaller disk until all the disk in the array were 3TB, afterwards I would make a new array with the left over 2TB, and use the 1.5TB for offsite backup of the important data
