When an allocation is happening on a raidz vdev, the number of sectors allocated is rounded up to a multiple of nparity + 1. If this results in the allocation spilling into an extra row, then the corresponding call to vdev_raidz_asize_to_psize will incorrectly assume that parity sectors were allocated for that spilled row, even though no data is stored there. If we determine that happened, we need to subtract out those extra sectors before performing the rest of the capacity calculation. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.
