Hi,
I'm trying to understand why extra blocks are added when you create a file
in the ext3 fs:
for example, let's create a file of 1111 blocks (4096 bytes for each block)
$ dd if=/dev/zero of=foo bs=4096 count=1111
the real occupation disk is then:
$ du -B 4096 foo
1114
instead of 1111
So where the 3 extra blocks come from?
Thanks for help!
youness
