I could not find any differences that would explain the behaviour.
Have you seen this before? Can you reproduce it on your systems? Do
you know how to get the CentOS 4 behaviour?
More on the point: I'm migrating some data from CentOS 4 to CentOS 5,
it's around 70GB of millions of small files. I would like it to still
take 70GB, not 140GB. For now, I'm working around this issue by using
"-T small" to mke2fs, I'm not sure if it's going to have the effect I
want, and I'm not sure about any other impact (performance?) it might
have on my filesystem.
