I have a 4 drive RAIDZ zpool, which now has 4x3TB WD Green drives. It started with 2x3TB and 2x2TB drives because that was what I had on hand. I have since replaced the 2x2TB drives with 3TB drives (resilvering with each drive). autoexpand was true prior to the replacements.
Each WD Green Drive reports 3.00TB
bosnas# smartctl -i /dev/ada3 | grep Capacity
User Capacity: 3,000,592,982,016 bytes [3.00 TB]
bosnas# smartctl -i /dev/ada2 | grep Capacity
User Capacity: 3,000,592,982,016 bytes [3.00 TB]
bosnas# smartctl -i /dev/ada1 | grep Capacity
User Capacity: 3,000,592,982,016 bytes [3.00 TB]
bosnas# smartctl -i /dev/ada0 | grep Capacity
User Capacity: 3,000,592,982,016 bytes [3.00 TB]
So I would expect the size of the zpool to be 9TB or 8.18TiB but
bosnas# zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
tank 7.25T 4.17T 3.08T 57% 1.00x ONLINE /mnt
I am assuming the size reported is in TiB, but that still leaves about 1TB that appears to be AWOL.
7.25 TiB is pretty close to 8TB so I am guessing zfs is still looking at the vdev as being built on 2TB drives. So assuming it was the autoexpand that failed, I exported the drives and imported them as per Enabling ZFS Pool Expansion After Drive Replacement. No change.
What am I missing?
