Hi:
That is say: in 2.4.x, the max filesystem size of ext2 is 32T, and i
want know
what is the reiserfs(and others) max size ? and where the limitation
comes from(VFS layer)?
Maybe you can give some clue .
And the max file size now biger than 2G(is 16T), how reiserfs implement it?
Thanx a lot!
zmwillow
Best regard

16Tb etc are file system internal limits. There is also a 1Tb or so block
device limit too

block numbers are a 32 bit int is the problem. sectors are also kept as
a 32 bit int, but that is a layer below reiserfs. block numbers become
64 bit in reiser4, but not sure when rest of linux goes to 64 bit block
numbers
