Section 5.4.4 says:
The equations given above for embedded parity can be used to map a file offset to the correct component object by setting the number of parity components to 2 instead of 1 for RAID4 or RAID5.
It should say:
The equations given above for embedded parity can be used to map a file offset to the correct component object by setting the number of parity components to 2 instead of 1 for RAID5.
Notes:
Clarify that the RAID_PQ algorithm extends the rotated parity scheme as specified for RAID_5.
