2nd Question:
When I format the partition with ext3, the df -k command returns:
------------------------------------------------
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb1 456730 8239 424908 2% /mnt
------------------------------------------------
I think 8239 KB (8.05 MB) was used by journal. But the amount of blocks
decreased after formatted (471665 to 456730). Why?
Well, the number of blocks was probably taken by ext3 stuff, but I am not
sure. As well, by default ext3 sets aside 5% (i think) to the root user, but
the can be changed with tune2fs.
The 5% reserved for root does not explain the drop in blocks in the
filesystem. That shows up in the difference BETWEEN the number of
blocks and the sum of those Used and Available.
ex: (8239 + 424908) / 456730 = 0.94836
Could the missing blocks (471655 - 456730) be the journal file, since
that is completely invisible and not accessable through the filesystem?
If so, what is using the 8239 blocks shown by df?
