Re: Inconsistent multi-block io

It is because,

  1. The missing blocks may be already in cache
    (If the block 5 is already in cache, you will see two multiblock reads
    of blocks 1-4 and 6-16)
  2. You may be hitting extent boundary
    (multiblock reads can not spawn extents)
  3. You may be hitting the last block
    (or hitting HWM)

There may be some more, but these are the most common .
