[vol_no:8][sanity:1][offset:55] (sanity bit is always 1 to catch programming errors).That allows 32768 TB per volume. I will probably steal a few more bits to abstract out a blockmap layer, but I can't imagine needing more then another 7 bits, giving us 256 TB per volume (x 256 volumes == 65536 TB).
What is a volume? Like a disk? I think we should shoot for considerably more than 256TB per disk. Looking at the current growth, that's about 10 years from now. And keep in mind that DragonFly already exists over 4 years, so time is running fast.
Sounds scary, but I think we should really consider if wasting bits is worth it.
