This has a direct impact on reliability (the MTTR enters into the MTDL linearly).

If you have a ZFS pool with parity (such as RAID-Z1, equivalent to your mdadm RAID-5 array) and the autoexpand=on property is set for the pool/vdev, you can use zfs replace to replace your disks one by one, giving the pool time in between to rebuild parity, or "resilver" itself.Then, when the last disk has been replaced and resilvered, ZFS will automatically increase …
