RHBA-2013:0538 - tuned bug fix update
Synopsis
tuned bug fix update
Type/Severity
Bug Fix Advisory (none)
Topic
Updated tuned packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
Description
The tuned packages contain a daemon that tunes system settings dynamically. It does so by monitoring the usage of several system components periodically.
This update fixes the following bugs:
-
Previously, the ktune service did not save readahead values. On startup, it multiplied the current value by a constant and divided the value by the same constant on stop. This could result in a wrong value being set on devices that were added after ktune had been started. Now, the previous readahead values are stored for all devices and the correct values are restored on ktune stop. (BZ#907856)
-
Previously, when multiple devices were added into the system, a udev rule restarted ktune for each new device. This could lead to many restarts in a short period of time. The multiple restarts could trigger a race condition in the kernel, which cannot be currently fixed. The tuned daemon code has been modified not to trigger more than one restart per 10 seconds, thus preventing the race condition from occurring. (BZ#907768)
Users of tuned are advised to upgrade to these updated packages, which fix these bugs.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
