That will mark the drive as offline, put the pool into a degraded mode, and generally be less harmful to the system. Then figure out which disk to pull and remove it (doing it from a powered off state if needed). Install the new drive, configure it however it's needed, then use: zpool replace <poolname> <old device> <new device> =E2=80=8B > Next question is: I'm about to replace the 3 TB HDD with a more recent an= d > modern 4 TB > HDD (WD RED 4TB).

And it will keep the extra space= as "usable in the future", so if you replace all the drives with 4 TB ones, the extra space will be added to the pool. --=20 Freddie Cash fjwcash@gmail.com
