I'm curious how you got that. Are you sure "a" is on /dev/sda1? What OS and FS are you using?

$ du -sh /tmp/a

4.0K a

$ tune2fs -l /dev/mapper/VolGroup00-LogVol00 | grep "Block size"

Block size: 4096

Positive that 'a' is on /dev/sda1. Running CentOS 5.5 and /dev/sda1 is ext3.

I get similar behavior on the other partition:

echo "a" > a; du -sh a

8.0K a

dumpe2fs /dev/VolGroup00/LogVol00 | grep "Block size"

Block size: 4096

Though if I 'touch' the files to create them, they are the blocksize. Which seems odd, since on my AIX and HP-UX boxes that gives files of size 0.
