Unterstützung für IBM iPDU Fencing-Gerät
Red Hat Enterprise Linux 5.9 fügt Unterstützung für das IBM iPDU Fencing-Gerät hinzu. Weitere Informationen über die Parameter dieses Fencing-Geräts finden Sie im Cluster-Administrationshandbuch. BZ#741985
Größenoptimierung der DLM-Hash-Tabelle
Der Distributed Lock Manager (DLM) ermöglicht nun die Optimierung von DLM-Hash-Tabellengrößen in der /etc/sysconfig/cman-Datei. Die folgenden Parameter können in der /etc/sysconfig/cman-Datei eingestellt werden: BZ#836963
DLM_LKBTBL_SIZE=<size_of_table>
DLM_RSBTBL_SIZE=<size_of_table>
DLM_DIRTBL_SIZE=<size_of_table>
Dadurch werden wiederum die Werte in den folgenden jeweiligen Dateien verändert:
/sys/kernel/config/dlm/cluster/lkbtbl_size
/sys/kernel/config/dlm/cluster/rsbtbl_size
/sys/kernel/config/dlm/cluster/dirtbl_size
