Hiya,

Of course that should have been 4 byte pointers. This would allow us to
index a disk that is 4K * 4G = 16TB in size (ie. Very big disks/stripesets)

Also the largest directly indexed file would be:

3584 + 63 * 8192 = 519680 bytes

The largest file would be:

3584 + 63 * 8192 + 64 * (8192 / 4) * 8192 = 1.0005 GB (big enough for any
conceivable caching purposes for the next 10 years I'm guessing).

Stew.
