make your filesystem faster

i found a tip to speed up your linux filesystem (ext3 and reiserfs) here and here.

To get more infos about this tweak, look at the links above.

You have to do the following steps: (note: you have to change the partition to your needs. In my case its: "/dev/sda8 /")

1) edit your /etc/fstab and add thing marked bold to your mount line.
/dev/sda8 / ext3 defaults,noatime,nodiratime,errors=remount-ro,data=writeback 0 1

2) edit /boot/brub/menu.lst and add the bold marked entry.
kernel /boot/vmlinuz26 root=/dev/sda8 ro vga=865 rootflags=data=writeback

3) it can be necessary to run update-grub after that. But its not necessary on my archlinux system.

4) To prefent errors add the new mode to your filesystem before reboot.
tune2fs -o journal_data_writeback /dev/sda8

5) to see if the changes went right, check it with:
tune2fs -l /dev/sda8
(you should do this again after reboot)

have fun with a faster performing system. ;)
