5.9. System Daemons

Power Management

In order to allow users to monitor the behavior of their systems and to improve power consumption in general, several improvements were done for Fedora 11:

Provide two new systemtap scripts to monitor disk and network activity of running applications
Add a workload framework package called BLTK to offer reproducible tests
Improved applications to reduce unnecessary disk and/or network activity
Enabled several new features to save power:
- relatime option for root filesystem /
- Automated start/stop of services related to hardware
- Enable USB autosuspend for known working devices
- Add optional tuned service to dynamically adapt system settings to the current use

Users of Fedora 11 should therefore see a reduction in power usage of their system.

pm-utils: The pm-utils power management utilities have been updated to 1.2.4. Some improvements have been made in logging and configuration.

mdadm

mdadm has been updated to 3.0. The significant change which justifies the new major version number is that mdadm can now handle metadata updates entirely in userspace. This allows mdadm to support metadata formats that the kernel knows nothing about.

Currently two such metadata formats are supported:

DDF - The SNIA standard format
Intel Matrix - The metadata used by recent Intel ICH controllers.

Also the approach to device names has changed significantly.

ntfs-3g

ntfs-3g has been updated to 2009.2.1 (from 1.5012). There are many changes in this new driver; see the upstream's release history at http://www.ntfs-3g.org/releases.html for complete details.
