- * Convert the zvol's volume size to an appropriate reservation.
+ * The theory of raidz space accounting
+ *
+ * The "referenced" property of RAIDZ vdevs is scaled such that a 128KB block
+ * will "reference" 128KB, even though it allocates more than that, to store the
+ * parity information (and perhaps skip sectors). This concept of the
+ * "referenced" (and other DMU space accounting) being lower than the allocated
+ * space by a constant factor is called "raidz deflation."
+ *
+ * As mentioned above, the constant factor for raidz deflation assumes a 128KB
+ * block size. However, zvols typically have a much smaller block size (default
+ * 8KB). These smaller blocks may require proportionally much more parity
+ * information (and perhaps skip sectors). In this case, the change to the
+ * "referenced" property may be much more than the logical block size.
+ *
+ * Suppose a raidz vdev has 5 disks with ashift=12. A 128k block may be written
+ * as follows.
+ *
+ * +-------+-------+-------+-------+-------+
+ * | disk1 | disk2 | disk3 | disk4 | disk5 |
+ * +-------+-------+-------+-------+-------+
+ * | P0 | D0 | D8 | D16 | D24 |
+ * | P1 | D1 | D9 | D17 | D25 |
+ * | P2 | D2 | D10 | D18 | D26 |
+ * | P3 | D3 | D11 | D19 | D27 |
+ * | P4 | D4 | D12 | D20 | D28 |
+ * | P5 | D5 | D13 | D21 | D29 |
+ * | P6 | D6 | D14 | D22 | D30 |
+ * | P7 | D7 | D15 | D23 | D31 |
+ * +-------+-------+-------+-------+-------+
+ *
+ * Above, notice that 160k was allocated: 8 x 4k parity sectors + 32 x 4k data
+ * sectors. The dataset's referenced will increase by 128k and the pool's
+ * allocated and free properties will be adjusted by 160k.
+ *
+ * A 4k block written to the same raidz vdev will require two 4k sectors. The
+ * blank cells represent unallocated space.
+ *
+ * +-------+-------+-------+-------+-------+
+ * | disk1 | disk2 | disk3 | disk4 | disk5 |
+ * +-------+-------+-------+-------+-------+
+ * | P0 | D0 | | | |
+ * +-------+-------+-------+-------+-------+
+ *
+ * Above, notice that the 4k block required one sector for parity and another
+ * for data. vdev_raidz_asize() will return 8k and as such the pool's allocated
+ * and free properties will be adjusted by 8k. The dataset will not be charged
+ * 8k. Rather, it will be charged a value that is scaled according to the
+ * overhead of the 128k block on the same vdev. This 8k allocation will be
+ * charged 8k * 128k / 160k. 128k is from SPA_OLD_MAXBLOCKSIZE and 160k is as
+ * calculated in the 128k block example above.
+ *
+ * Every raidz allocation is sized to be a multiple of nparity+1 sectors. That
+ * is, every raidz1 allocation will be a multiple of 2 sectors, raidz2
+ * allocations are a multiple of 3 sectors, and raidz3 allocations are a
+ * multiple of of 4 sectors. When a block does not fill the required number of
+ * sectors, skip blocks (sectors) are used.
+ *
+ * An 8k block being written to a raidz vdev may be written as follows:
+ *
+ * +-------+-------+-------+-------+-------+
+ * | disk1 | disk2 | disk3 | disk4 | disk5 |
+ * +-------+-------+-------+-------+-------+
+ * | P0 | D0 | D1 | S0 | |
+ * +-------+-------+-------+-------+-------+
+ *
+ * In order to maintain the nparity+1 allocation size, a skip block (S0) was
+ * added. For this 8k block, the pool's allocated and free properties are
+ * adjusted by 16k and the dataset's referenced is increased by 16k * 128k /
+ * 160k. Again, 128k is from SPA_OLD_MAXBLOCKSIZE and 160k is as calculated in
+ * the 128k block example above.
+ *
+ * The situation is slightly different for dRAID since the minimum allocation
+ * size is the full group width. The same 8K block above would be written as
+ * follows in a dRAID group:
+ *
+ * +-------+-------+-------+-------+-------+
+ * | disk1 | disk2 | disk3 | disk4 | disk5 |
+ * +-------+-------+-------+-------+-------+
+ * | P0 | D0 | D1 | S0 | S1 |
+ * +-------+-------+-------+-------+-------+
+ *
+ * Compression may lead to a variety of block sizes being written for the same
+ * volume or file. There is no clear way to reserve just the amount of space
+ * that will be required, so the worst case (no compression) is assumed.
+ * Note that metadata blocks will typically be compressed, so the reservation
+ * size returned by zvol_volsize_to_reservation() will generally be slightly
+ * larger than the maximum that the volume can reference.
