I don't get it: I thought ext2/3 filesystems (volumes) can be 32TiB in 
size? At least that's what [0] says. If this is wrong, someone should 
correct this information. Although I must admit that 16 TiB per fs makes 
more sense, given that with a max blocksize of 4K and a max of 2^32 
blocks we have 16TiB of data.... Where does this 2^32 limitation come 
from anyway?

BOFH excuse #247:

Due to Federal Budget problems we have been forced to cut back on the number of users able to access the system at one time. (namely none allowed....)
