Bug Fixes

BZ#1129936

Previously, the tuned service did not support direct-access storage devices (DASDs). As a consequence, DASDs were ignored by tuned and as a result were not configured. This update adds support for DASDs to tuned, and DASDs are now properly configured.

BZ#1036049

On Red Hat Enterprise Linux 6, the /etc/sysctl.conf file is the default configuration file for the sysctl tool settings and overrides can be specified in the /etc/sysctl.d/ directory. The tuned service previously handled the settings the opposite way, which is common in certain distributions. Consequently, the configuration specified in /etc/sysctl.d/ could be overridden by /etc/sysctl.conf. The way tuned handles /etc/sysctl.conf and /etc/sysctl.d/ has been reversed to match the Red Hat Enterprise Linux 6 logic. As a result, /etc/sysctl.conf is now processed first and can be overridden by settings in /etc/sysctl.d/.

BZ#1159963

Prior to this update, the tuned service did not support Xen Virtual Storage Devices (XVDs). Consequently, XVDs were ignored by tuned and were not configured. Support for XVDs has been added to tuned, and XVDs are now properly configured.

BZ#1174253

Previously, the value of the vm.max_map_count sysctl settings was set too low (1,000,000) in the sap-netweaver tuned profile, which could affect performance. With this update, vm.max_map_count is set to 2,000,000, which is a value recommended by SAP documentation.

BZ#1017366

Previously, certain files from the tuned packages could be incorrectly considered to differ from the RPM database. As a consequence, RPM verification performed by running the "rpm -V tuned" command could fail and it could be indicated that the files were changed despite not being touched by the user. This update excludes several attributes, such as size, md5sum, and mtime, from the verification of the files, and RPM verification no longer fails.

BZ#1064062

Due to a typographical error in the latency-performance profile in the SYSCTL_POST variable, the /etc/sysctl.d/* files were not processed by the tuned service. This update fixes the typographical error, and the /etc/sysctl.d/* files are now correctly processed by tuned.
