Disk Performance Tuning
On my laptop I use EXT3. My fstab is setup for speed.
I turn off atime and set the mode to journal_data_writeback.
The data consistency guarantees are the same as the ext2 file system.
This is still better than ext2 because file system integrity is maintained
continuously, so the file system is always consistent even after an unclean shutdown.
In other words, you made loose data, but you won't have bad data.
/etc/fstab
Do not forget to read Before you reboot before you make changes to /etc/fstab.
Edit /etc/fstab to change ext3 mount options:
# /dev/sda1 UUID=d4769677-d2a9-4d87-9165-fc44760495bc / ext3 defaults,errors=remount-ro,noatime,data=writeback 0 1
Older systems might use the /dev/hda1 notation (if upgrading you can get the UUID using the vol_id /dev/hda1 command):
/dev/hda1 / ext3 defaults,errors=remount-ro,noatime,data=writeback 0 1
Before you reboot
Run this before you reboot after changing /etc/fstab.
tune2fs -o journal_data_writeback /dev/sda1
