[Gllug] ext3 options

[Emon]

Hi all

I made a 11GB partition on my HDD (for storing stuffs like
software,songs etc.) with ""cfdisk" and then did "mkfs.ext3" &
checked the size with "df -m"

It displays the size to be "10321".

My first question is where has the (approximately) 900MB gone??

Also I found this in "man mke2fs"

*****************
-m reserved-blocks-percentage
Specify  the percentage of the filesystem blocks reserved for
the super-user.  This avoids fragmentation, and allows
root-owned daemons, such as syslogd(8), to continue to function
correctly  after  non-privileged  processes are prevented from
writing to the filesystem.  The default percentage is 5%.
*****************

Since I don't understand the function of "syslogd" (tried
reading the man-pages, but that didn't help either) I am asking
you guys, do I actually need to keep 5% (500MB approximately for
11GB) of reserved-blocks??

Thanks
Emon
