Description

This is a ZFS tunable for pools with heavily imbalanced vdevs. If the threshold is set to non-zero and a vdev is more full than the threshold we stop making allocations to it until all other vdevs are just as full. This is a much better way to focus writes on newly added vdevs to balance the pool than the old zfs_mg_alloc_failures.
