Our ZFS spares handling system sort of relies on our patterns of disk usage
This is a question with a subtle answer, which starts with how we use disks and what that implies for available spares. We always use disks in mirrored pairs, and the pairs are fixed; every partition of every disk has a specific partner. The first partition of the first SAS-connected disk is always mirrored with the first partition of the first SATA-connected disk, and so on. This means that in normal operation (when a disk hasn't failed), all spares also come in pairs; if the last partition of the first 'SAS' disk isn't used, neither will be the last partition of the first 'SATA' disk, so both are available as spares. In addition, we spread our partition usage across all disks, using the first partition on all pairs before we start using the second partition on any of them, and so on.
