[LI] DU problems

[Gandalf Mithrandir <gandalf@xxxxxxxxx>]

Dear Folks,

To clear up one small doubt: Check out this link for a definition of a Guru.
I'm a longtime lurker and a recent and rare poster. I'd wonder if I'm even
remotely eligible - consider all that I've been reading on the history of
Linux - I'd say I'm more than a plain newbie - I'm a very awe struck one!
Calling the Gurus was an initial post by Rohit, Digest #343, incidentally.
Thou, I'd really think that there is only one true Guru on this list - Prof
Guru<nandan> Bhatt ;-). Sorry. Could'nt resist that one.
Apart from many other things that I've been wanting to post, I'd entirely
forgotten about Chetan's 'du' problems. Well, I did some testing as well,
and I've found some VERY interesting results. Ok, some baseline info, I have
Linux (PCQ RH6.1 - ext2fs ), Win98 (FAT32), NT (FAT16) running on a machine.
I took three files, of varying sizes, tinkered around and du'ed em on each
filesystem. Results are here:

FileSystem	Size Reported	Size in Kb

Test 1
Actual		355328		347
FAT32		356352		348
FAT		360448		352
ext2fs		360448		352

Test 2
Actual		100000		 98
FAT32		102400		100
FAT		131072		128
ext2fs		106496		104

Test 3
Actual		  55328		 55
FAT32		  57344		 56
FAT		  65536		 64
ext2fs		  61440		 60

Ok, first things first.
FAT 	== Ok. 8kb file allocs, every file = minimal integral multiple of 8kb.
FAT32 	== Ok, 4kb file allocs, every file = minimal integral multiple of 4kb
ext2fs 	== Blah? bzuuurg. What's happening? It's supposed to be a minimal
integral multiple of 1kb <it is an integral multiple of 1kb, thou ;-)>. From
where it's supposed to be
347 	changes to	 352?
98 	changes to 	104?
55 	changes to 	60?

If Chetan was confused in the first place, man, am I clear after all this or
what!!!!! SOMEBODY help!! What is going on ? Someone with filesystem info?

ReSourcefully,
M

p.s RAVIKANT K RAO,

Fate / providence had nothing to do with it. Apart from the many other
things that you got so completely wrong, there is NO Chem Engg course at
UVCE. So, you either got the course or the college or both wrong. In any
case, no harm done, fate was on UVCE's side I'd assume ;-).
