It is to be said that the performance of md RAID0 is somewhat better than from striped LV's but I would prefer LVM if I could extend a striped LV without rebuilding RAID/restoring data. cu, Jan -- _______________________________________________________________________ THE BEST RUN E-BUSINESSES RUN SAP _______________________________________________________________________ Jan Schreckenbach email: Jan.Schreckenbach@sap.com SAP AG Walldorf/Baden, Germany Phone: +49 6227 7-47474 LinuxLab Fax : +49 6227 78-31414 SAP LinuxLab support address: linux@sap.com
